The world has been depending on burning fossil fuels for energy, throughout all these years. With dependence on fossil fuels, soon enough these finite materials will be depleted. Not only that, but it also has adverse effects for the environment, everything from air to ocean and land pollution.

Fossil fuels include, coil, oil and natural gas, with the latter being cleaner that oil and coal in terms of emissions. Let's also keep in mind how strenuous of a process it is to extract oil, promoting environmental disasters.

Most common renewable energy sources include, solar energy, wind energy, hydro energy, tidal energy and a few others.

The big question here is, can the world be 100% dependent on renewable energy sources? How can that be achieved and are they sustainable?

I think we have a problem of places investing in things THEY can easily use. Places like north Western Europe with a lot of coastal areas have done extensive research on wind power and hydro electric as they're the most usable in those places). It's kinda been helped by China doing a lot of research into making solar but all of these power sources require emissions to be produced imo and solar might require unrecycleable plastic (I'm not sure if there are any mostly silicon versions available though).

Many countries in the world also have a condition for reducing carbon emissions. The EU still targets itself at 50% renewable power consumption (set in law) and the UK receives wind power for most of the year other than a few days every few months (I think they're designed to function at speeds between 20mph and 50 so if the wind speed is too low or too high it has to be turned off).

Energy is a really complicated topic. There's a massive number of ways you can combine production and distribution, and figuring out the optimal balance for any geographic area requires a lot of surveying and understanding of the local environment, natural resources, as well as trade relationships between neighbouring countries.

I think renewables will be forced onto consumers in the developed world, especially in the West. This isn't inherently a bad thing, but depending on some of the factors I mentioned above, there will be pos/neg consequences at smaller geographic scales. For example, NYC just decommisioned (https://www.eia.gov/todayinenergy/detail.php?id=47776) a nuclear power planet, leading to blackouts throughout the state and NYC. California also voted to decommission Diablo Canyon (https://blog.ucsusa.org/mark-specht/diablo-canyon-is-shutting-down-is-california-ready/), and they have no plan for an alternative source of energy, they just state it has to be carbon neutral. These are (in my opinion) poor choices, and will have extremely negative consequences regardless of the renewable energy source that may or may not fill in the gap.

Poor excuses for switching to renewables aside, there are legitimate problems with renewables. They're still much more unreliable than oil/natural gas, storage of excess energy is an issue (one that Bitcoin mining can actually help alleviate), and the actual production of things like solar panels require rare earth materials and metals which are mined in developing nations with poor regulatory oversight. Often, the extraction and purification of these materials results in environmental degradation that goes unchecked in parts of the world where end consumers tend to not care about (so much for "clean" energy). These issues will be resolved or become insignificant enough to ignore over time, but they exist for now and it's silly to pretend renewable energy is some holy grail that we can just have for free (which is how politicians treat it).

So in the short term, I expect a lot of decommissioning of functioning nuclear plants (bad) and aging coal/gas plants (better). In the medium term, these things will be replaced by renewables where they make sense, some countries/provinces/states may just decide to stop producing energy and start importing it entirely. In the long term, I think we're looking at nuclear, although if people were serious about stopping climate change, we would be building nuclear plants at a monotonically increasing rate.

Of course they are the future, oil and gas is a limited resources, and it's also very important for chemical industry. People of the future would be blaming us for burning it not only because of global warming, but also because they will have less oil to make plastics and chemicals. And you should also consider that oil as we know it can currently only be found on Earth, because we don't even know about any life outside of Earth.

However, nuclear energy is not considered renewable, but I think it's also the future, it's getting bad rep because of crazy eco-activists, but it is clean and most of the nuclear materials will not be needed for other purposes, so it's okay to use it for energy.

In one shape or form renewable energy will cease to be seen as separate to any other energy source just preferable for its efficiency as much as other types, just requires more refinement and investment I think.
   It may not be exactly as some perceive now, for example bio diesel can be developed from strains of algae.  This is possible today but its not cost efficient as the diesel though natural is hard to produce on a massive scale required to compete with simply extracting ancient reserves but in future it may happen to be the main source of fuel.   Its disappointing how little tidal energy is being used, thats just a case of engineering making use of such large changes every day.

Without doubt renewable energy resources are going to be the future for different reasons. Renewable energy sources are clean and can be maintained at a very low cost, but it requires large investment for the initial set-up. Another factor is the usage, it depends on the surrounding for its power generation. So, the power generation can't be expected to be stable in all occasions.

Most of the renewable energy resources were expensive to setup. Same as the advantages there'll be disadvantages with these. The important part, it can be overcome with the growing technology and efficiency can be achieved lowering the pollution and release of toxics.

I mean without it, with the limited supply we have of resources, we'd inevitably end up going down as a dying civilization in the long run. Yes, the setup is expensive when it comes to renewable energy and there'd probably be a lot of prep we actually need to do, but it simply means that it's worth the price since we aren't looking at it from a short term perspective, it's a long one, a very long one at that. It's still under research anyhow on how to effectively use it so, at the very least, we're progressing.

And Idrk if the question is answerable since I don't know much about the current progress, but it should be obvious if its possible if you observe the improvements and what not that's happening in relation to it.

I don't know how it will be in other places, but where I live they are very interested in this. Because the effects of climate in recent years are becoming more and more obvious, and reducing the amount of CO2 into the environment is considered very necessary to protect the living environment.
Although economic conditions do not allow everything to be universal, I have seen many solar panels or electricity produced from wind turbines.

Nuclear energy isn't actually renewable, if used correctly though, it's a quite efficient and clean source of energy. However, it's not really the safest, if something goes wrong, we're pretty much screwed.

The question is, can the whole planet be dependent on renewable energy sources? The EU currently has targeted to reach 40% until 2030, will it be surpassed? If I'm not mistaken, the current share of renewable energy sources is approximately 20%.

Do we have a choice? Non-renewable energy sources are finite. They are not unlimited. Sooner or later they will be depleted. The world's population is rising. Along with that is the rise of energy demand. Urbanization is creeping quite fast. That also means energy demand. Technologies are sprouting everywhere. They also demand power. If we are to depend on non-renewable energy sources, what happens when they finally run out one day? That is why we need to tap renewable sources. They are indeed the future.

Are they future? Oh yes definitely they are the future. But are they going to be there 100%, that’s big No. Unfortunately its not happy thing to say but there are many challenges while using the renewable sources which primarily contains Solar, Wind, Tidal power etc. More news ways are also being invented every time but with low success rate of getting used. This is because of the cost involved to build the structures. In addition to this Nature is not always happy with humans it can destructing and sometimes the Sun can be so shy you would die to freez.
I’m just saying this shorty but if you think about it deeply you will understand how things can go wrong if we think about 100% nature dependence. Different geography, different weather cycles and more factors to affect continuous production of clean energy.

Yes the world can be 100% dependent on renewable energy, it can be achieved if the government were to start adopting it and destroy the oil and fossil fuel companies because they are the biggest opposition of the renewable energy resources, mind you that electric cars were a thing already back in the 60s but it was so suppressed because they care more about the profit rather than innovation. To make it sustainable, we have to create a new kind of battery that can be molded into industrial level and commercial kind because renewable energy gathers a lot of energy but some of them dissipates because there's no storage or if there's one, it's not a proper one.

Yes, we need to have renewable energy because if we still use the current energy, the earth will damage and the pollution will be at all places. With the situation now, the earth was already screaming about the carbon and another emission that every country uses, so it needs environmentally friendly renewable energy.

I think this is all country's concern to start using renewable energy. Still, it costs highly because they need to invent new tools or peripheral that can support that renewable energy. But once that tools or peripheral can be mass-produced, the cost can reduce so all countries will not have to pay a high cost to implement.

That's what I also believe. It's highly unlikely that the whole world will be dependent on renewable energy sources. They are quite expensive to implement and complicate. I think that these two ways of creating energy will co-exist for many years to come.

On top of that, not all countries can depend on solar energy, for instance, we have more than 300 days of sunshine per year, thus, some areas could possibly benefit from solar panels.

If we can improve efficiency and create new tech to lower the cost, then it will be cheaper in the future. I think it's just how tech works. Just take a look at the computer market for example. You can find a fast processor for under $100 now, which can compete with the top 10 CPUs in the 90s, and so on. Tech will improve, so time will tell whether we can solve that problem or not.

Unless it was monopolized, and the government doesn't support innovation, I don't think lowering the cost will be a huge problem.

Yes we can make our energy sources renewable if we as humanity abolish the current energy industry that only aims to profit but not care about the pollution that they are emitting because they don't care about the future generations. If the people in position and power have integrity and won't easily be outshined by money, we will probably see a future where we are reliant on renewable energy.

I agree, renewable energy sources will be cheaper to implement in the future, they are a relatively new technology, which is now facing a larger adoption.

Just like mobile phones, which were way too expensive 10 years ago, and now they are dirt cheap. Solar and wind energy are the most basic source someone can have, I don't know how efficient they are though.

Renewable energy a resource for the future.
Most time when the word future is mentioned, majority thinks it the next fifty years or next generation to come but the simple truth about future to me is the next second.
Renewable energy been classified as a thing of the future is inappropriate.
The truth remains that renewable energy is in almost all part of the world today. But it sustainable is the major challenge.

Green energies and sustainability projects are things that institutions and individuals pressure large companies to reduce the lack of concern for the environment, but this does not mean that they should get rid of traditional sources and resort to alternative energies.
Green energies are not always green, there is a lot of waste that is generated from it and some of it ends up in the dumps, which represents another problem (recycling).

I believe that there will be a balance in the sense that the number of harmful waste that exists globally, there will be requests to reduce emissions, increase tree planting, and reduce sources harmful to the environment.

In an environment where the world is running out of conventional fossil fuels, it is refreshing to learn about the renewable resources that are now a reality. Alternative energy sources such as solar and wind, biomass, geothermal and hydropower seem to be a future of this world, with innovations such as "smart" products that harvest energy by tapping into the environment. I am a supporter of renewable energy sources, with hydrogen fueling cars (combined with electric cars) and fuel cells as a feasible replacement for fossil fuels. But, can the world be 100% dependent on renewable energy sources? My belief is that it is possible. The question is only how long it will take and what it would take.

A few years ago, I believe that renewable sources of energy are not viable, because they are much more expensive when compared to fossil fuels. But the technological advancement in this field has made wind/solar/tidal/geothermal energy very competitive when compared to the other sources. One big issue is with oil. While renewable sources of electricity will be able to replace coal and natural gas in electricity generation, there exists no good alternative for gasoline driven vehicles. EVs are 2-3 times more expensive when compared to gasoline driven vehicles. I just hope that this situation will change in the near future.

the problem in my opinion is not the renewablitiy or the pollution that some energy production methods (such as burning fossil fuel) produce but the problem is the efficiency of these methods.
for example how much energy can burning a gallon of crude oil produce? compare that with a gallon of gas.
how much can a single solar panel produce and what happens when it is cloudy?

i think in the future the focus is going to be more on the efficiency. imagine a single nuclear plant that can power then entire country.

The world will not be 100% dependent on renewable energy sources anytime soon.  I believe that renewable energy sources are meant to coexist or complement fossil fuels. I can only say that the world will definitely experience a decrease in the dependence on fossil fuels. However this is going to happen more in developed nations where they have the resources, policies and enabling environment to adapt and adjust. In underdeveloped countries, hmmm, I don't think so.

No matter how much progress the world has made now with  solar energy, wind energy, hydro energy, tidal energy etc we still have a long way to go and lots of ground to cover.  Personally I am delighted that solving climate change issues, ensuring access to affordable, reliable, sustainable and modern energy for all are part of the Sustainable Development Goals (SDGs). Soon we'd achieve them

Yes, definitely. bitcoin and bitcoin miners can be the course of this adoption because there are bitcoin is under pressure from some people who believe bitcoin is consuming too much energy and making the earth warmer. After this stuff happening we can see many major miners are trying to use more renewable energy and decrease the usage of fossil energy in the world. In my idea, the government and the organizations that try to do some progress with renewable will be the most powerful ones, because soon after people find out what they did to earth they will rush to use renewable energy resources.

The main problem with renewable sources is their consistency, for example in the case of the wind you can get a lot of energy form it if the wind is blowing strong but none if there is no wind, and you cannot have a country stop just because there is no wind, so I think we could get through a point in which the majority of the energy is generated by renewable sources but we are still going to need some fossil energy sources so we have a backup in the case renewable sources are not generating enough energy for a few days.

It might but most of the energy source we have today are powered by Coal and Natural Gas. World Data on Renewable Energy (https://ourworldindata.org/renewable-energy)  So far most countries opt to use renewables depending on its geographical location and energy yield. If developments regarding efficiency and power delivery are being enhanced exponentially yearly we might achieve it.

My best bet is Tokamak (https://www.iter.org/mach/Tokamak) will be available to provide a massive leap in our energy crisis. Thus, solving our power needs and might lead to even new frontiers.

I think the only way this goal can be achieved is solar energy. solar is really the only real unlimited energy which we are really wasting. Also there are very minimal effects on the nature if we use this energy. Infact if solar energy is used on Massive scale it could even result in reduction of global warming altogether. And I am pretty much sure that we will be using methods to use this energy the most. Home solar panels are already the new cool where everyone is focused on making this one time investment, sooner or later we could be self sufficient in our power needs.

I have heard a lot about Tokamak. But the truth is that after more than half a century of research, the technology is still not safe enough to produce electricity on a large scale. Some two dozen or so Tokamak reactors are currently operational. But all of them are either research or experimental reactors. In theory, nuclear fusion is one of the best methods to generate electricity without any environmental damage. But I am afraid that we are at least a few decades away from doing that outside research purposes.

I also starting my journey using this system and from where am I where electricity is really expensive, the risk

of buying solar panels and other devices to make this system works is not that cheap. But from this previous

generations of electricity where i can enjoy unlimited energy without worrying for another high monhtly bills

I think solar energy if being focused well, may be a big help for communities.

If the cost to buy solar panels is not too expensive, people will prefer to buy that and will install at their home to reduce the electricity fee. But unfortunately, not many people can buy solar panels and can only use the current electricity they already used years ago. But I am sure that in the future, when the raw materials price to make solar panels is reduced, the cost will also reduce.

It's a two-part issue. Whilst renewables are getting cheaper, non-renewables will also become increasingly expensive as easy-to-reach reserves become ever more depleted.
Green, renewable energy certainly should be the future from an environmental, climate-change angle... but I think it will be the future not because it is better morally, but because as costs drop and the costs of non-renewables rise, it will be cheaper. Money tends to be the driver of decision-making.

A few posters have mentioned nuclear fusion, and this is of course the end goal. While the joke is that this is always a couple of decades away, there have been some major advances recently and some quite innovative new designs, notably from CFS (a spin-off from MIT)... they hope their new compact design (https://cfs.energy/news-and-media/new-scientific-papers-predict-historic-results-for) can demonstrate net gain by 2025. There is at least the possibility of a commercial reactor within the near(ish) future. I remain optimistic.

In my opinion these are the energy sources of the future, because most of the resources such as coal, oil, .... we humans have exploited are increasingly exhausted and if there is no alternative resource. OK. It is very possible that one day humanity will return to the primitive age without electricity without modern devices as it is now. but currently it is very limited and is only widely used in developed countries with modern scientific technology.

A case could be made for renewable energy representing the future, due to them producing energy more affordably in contrast to fossil fuel based energy.

But there is future technology with the potential to generate power more affordably than current day renewables.

A catalyst could someday be found to separate water into hydrogen and oxygen more efficiently. Paving the way to a hydrogen based economy becoming more sustainable. There are researchers who are actively pursuing this, as far as I know. Every few years one of them claims a breakthrough.

Methane based solutions could gain favor due to methane being more damaging a greenhouse gas than carbon, per gram. Burning methane I think produces carbon which is better for the environment than methane is.

If closed loop steam engines powered by sunlight could be developed. I think they would have a cleaner carbon footprint than current renewables. The way it might work is, big mirrors focus sunlight on a steam boiler. Using special materials to insulate and contain the heat. Water (or molten salt at very high temperatures) boils producing steam. Which drives the engine. In a perfect world, the boiled water would be recollected in a closed loop so water wouldn't need to constantly be added. The good thing about steam engines is they can last 100+ years. While the longevity of windmills and solar panels is far shorter.

There's a list of potential future energy sources, which could be developed if science continues to progress.

There is no doubt.

The electrical vehicle (EV) industry has been gaining a lot of traction and will only continue to do so into the future. Investors are just becoming more environmentally conscious in general by the day regardless of the area we are talking about.

However, be careful of the fact that adoption of renewable energy doesn't necessarily equal an increase in the stock price of certain EV makers or whatnot. They are very loosely correlated.

Renewable energy is on this planet and it still is most parts of the planet provide this kind of energy. The biggest flaw they have is the pollution they cause during their use and disposal environmental pollution leads to serious environmental problems and well known climate change but before investing, we need to analyze the market and be aware of the market environment as much as we are aware of the market environment. In the future the demand for electricity will increase five times which can be the only solution at the same time, the problem of greenhouse gas emissions can be solved.

I see that innovations about renewable energy sources are actually starting to be discovered by people without education degrees around the world and unfortunately the government doesn't even pay attention to it and doesn't even bother to make further research studies.

Like a non-formal education dormitory in my area, because they don't want the government to intervene in any financing, including subsidized energy sources, they make their own hydropower-based electricity network which has been used as the main electricity supplier both in the dormitory to the houses of local residents for many years to date.

The renewable energy sources you listed could be as bad as the effects fossil fuel and others have to the world if used wrongly. I have identified few issues with 2 in the list, and they can easily be proven. I won't be surprised if others have worst problems.

What is important is to use the natural resources safely. I guess it's very important that qualified people in this area look for ways to extract them safely and what the minimum amount that can be considered safe for extraction. They should be produced and used in ways that is safe for humans and our world.

Yes it is the future, with renewable resources, we will be able to survive with just those things because the energy source for renewable energy is everywhere unlike the current fossil fuel that we use where mining is needed and destruction of the environment. There's a good video by Kurzgezagt that tackles this although they focus on nuclear energy.

Renewable energy doesn't emit pollution, I mean why would they advocate the use of it if it's can contribute to pollution? Maybe the manufacturing of some of them is probably bad but given how there's a lot of innovations in the field, it's unlikely they contribute that much, when was the last time you've seen a solar panels emit smoke and dangerous funes in the atmosphere?

Definitely yes,but the technology has to be way more effective and affordable,which is totally achievable in the next decades.
Another great idea is nuclear power plants,that are using thorium instead of uranium.Thorium is way more accessible than uranium and the nuclear waste from thorium is way less,compared to the nuclear waste of uranium.I know that nuclear power plants using thorium have been tested in the USA without any issues,but the project has been abandoned.
Geothermal energy also has huge potential,but the cost of draining is very high.

Unfortunately the oil industry is not a cheap industry, they are making hundreds of billions of dollars every single year, do you really think that it is easy to say "stop this whole industry all together"? Of course not, how are you going to tell people to stop 100+ billion dollars worth of sector so suddenly. They are doing whatever they can to keep this going, they are even spending billions a year combined towards worlds superpowers and the politicians there, paying millions to thousands of people all around the world is not cheap.

So basically renewable energy does have a good future, many people support it, and that means there will be more of it in the future, but that will not make oil be gone, I am pretty sure it is going to keep going for a long time and that is going to be the doom of the world unfortunately, just because some people wanted money, we will all die.

before it is widely used, of course the new invention must be more profitable and less negative effects. indeed, solar panels can be an alternative source of energy, and of course this is a technological development that is more environmentally friendly. and I think that with continued research, other energy resources will emerge which will be more effective and efficient in the future

Another problem with those renewable sources of energy and other devices that use it is that they use a lot of materials that are not as abundant on the surface of the earth and that also pollute a lot, so they are not the panacea that environmentalists wants to make us believe, and when we add that it is more expensive to generate energy with those methods then it is understandable why they are still not as popular as the fossil fuel alternatives.

In theory no, the world is far from being able to solely relay on the renewable energies such as solar or hydro, due to the fact they are not that efficient, but i am surprised that no one mentions nuclear energy, believe it or not it is actually considered as a clean energy, it has zero emissions and it is know for producing a high amount of energy compared to all the other renewable and non renewable resources, maybe a lot of people have the wrong idea about it and they think its dangerous, but it is really not, not at the current technological and technical advancement that we reached, and i really think that the solution lies with iot and if we develop it more we could make it work.
PS: here is a link to a YouTube video explaining it if anyone is interested :https://www.youtube.com/watch?v=EhAemz1v7dQ (https://www.youtube.com/watch?v=EhAemz1v7dQ)

The thing is, we do not have a choice but to eventually switch to renewable resources in the future. Fossil Fuels take too long to become useful, millions of years to be exact. Not to mention the damage these non-renewable energy resources inflict on the environment which will eventually kill the planet if left neglected. There are a lot of benefits with renewable resources that the only thing stopping our generation from finally switching towards their renewable counterpart is the fact that corporations are very stubborn against this change since this will heavily damage their profits altogether. Really cool that I get to see a fellow crypto enthusiast who watches Kurzgesagt videos as well, but I digress. As I have mentioned above renewable resources are very sustainable for many reasons, including the fact that you can pretty much harness its source from virtually everywhere. And it's not like our species will have a choice when faced with the fact that we will inevitably die if we keep on using non-renewable energy sources that are not only inefficient, but are also toxic and damaging to the environment

That is not always the case. For example, for the manufacturing of solar panels, all you need is Aluminum and Silica, and they are quite abundant. The minor components such as acrylic plastic and copper cables are also not that difficult to source. And once the cells are damaged or expired,they can be recycled with minimal effort. Same for wind power generation as well. The turbines are mostly made of steel, and secondary materials include fiberglass, plastic, copper and aluminium. Tidal energy turbines also have similar composition.

There's no need to fully develop another iteration of solar panels, what it needs to do is to make it more commercial because it's still expensive as it was first released to the public, and we don't need to just focus on these things, we need storage for energy because most energy that is harvested is either wasted or dissipates over time because there's no proper storage for it.

Renewable energy cannot be stored because it is contineous replinishment process, and i believe this will be the future resources of energy since now mostly the world rely on using fossil fuels and time come we all realize what damage have been brought to our beautiful planet before it all exhausted.

why theres still getting energy from fossils if renewable energy is sustainable ?
 it only means isnt because the energy that we get from renewable can be weak and there are factors that affects it like weather and climate change .
it was like crypto and fiat we need both of them but it was adviced that we can prioritze the use of renewable energy because its more greener .

It needs to be more efficient, the first capital required to make it work is still quite expensive, and it is very hard for cities to use it because we just have tall buildings that use a lot of electric and solar can't cover all of that for a building even if you had a solar panel roof. So, it is going to be improving a lot both amount of energy created from a smaller space, but also the capital required for it as well. All the R&D on the solar panels are exactly like that, it is not going to be that much of a difference for now because it is not something that gets better overnight, but in 10-20 years we are going to look at today's tech and realize how horrible it was.

The problem is that the coals, the oils, the gas types of the world are ruining the climate of the world and we do not have too much time, unfortunately since renewable energy is very expensive, people literally let the world die before they spend a few more thousand dollars.

Of course, it's not going to stop anytime soon, however, it would certainly be beneficial for the environment to even have 50% of the whole energy production stemming from renewable resources. On the other hand, like someone already pointed out, if solar panels ever become affordable for the public,    then the majority of us could adopt it on our own housing and produce our own energy.

Definitely. This will be the main thread anyway.
It is not known what technologies we will eventually come to, but it is unambiguous that if we continue to emit as much CO2 as we emit now, we will simply drown in planetary disasters.

I don't think so, electric vehicles have begun to be en masse and it will definitely reduce human-generated carbon emissions. green energy and electric vehicles will reduce the suffering of the earth produced by humans so far.

Electric vehicles are the future, I also believe that. However, in most countries, they are not widely adopted by the public, since most have somewhat limited range, while not all countries have the necessary infrastructure. Here in Greece for example, they have now started gaining ground over internal combustion cars, with more and more chargers being placed around major cities.

Surely, renewable energy is our future because it is next to impossible to keep on using fossil fues because there are so many problems associated with using oil and gas. Therefore, there are so many scientists that are thinking about how to reduce carbon emissions and start using renewable energy without missing out on modern technologies. We have already witnessed the consequences of greenhouse effect and global warming and it is absolutely clear that the humanity needs to do something about it. More than that, renewable energy is extremely trendy now. Look at the tesla cars which are considered to the scientific breakthrough nowadays. Also, they are much cheaper to use.

Energy is a necessity for each and everything. Renewable energy generation is getting importance and more things are under development. As a beginning electric vehicles are promoted much against the gasoline vehicles. More and more innovative ways of electricity generation is found in its concept level. Maybe those into real-time implementation could make the cryptocurrency network consume low power and provide efficiency.

Renewable energy is a great perspective in terms of environmental protection and it would be really good if in the nearest future it would account for most of the energy production.

However, the methods you’ve mentioned need some improvement and reasoning before the global launch, otherwise, it will just lead to another environmental disaster.

For instance, solar panels are ecological, but their production is not. In addition, they have a lifetime, which means that at some point disposal is required, and the latter is quite expensive and complicated.

Hydropower plants don’t cause any carbon emissions, but they require a big amount of water and such facilities occupy a large area. As a result, they can affect the environment by interfering with what was a natural habitat for many organisms.

Wind and tidal energy are better but not as sustainable as they are dependent on external factors.

Renewable energy resources are some sort of technological advancement to be able to save up from consuming all of those limited non-renewable energy resources from being drained or consumed. It is kind futuristic and would be a great help if the counterpart or consequence will not play a damaging role that could cause to intensify the state of global warming. The idea of renewable energy resources is great if handled properly for we are really in need of those methods so conserve non-renewable energy resources from being consumed to its final extent.

People are now seeing rapid and real climate change on our planet, and this is what is already forcing states and their governments to take appropriate measures to reduce the influence of people on this already almost irreversible process. Now many countries, especially Europe, are adopting programs to replace carbohydrate energy sources with renewable sources in order to reduce the negative human impact on the environment. When a person faces a choice: to die or or to switch to other sources of energy, finally, the monopoly of those who are behind the extraction of oil, coal and gas can be moved.
In addition, technologies for the extraction of renewable energy sources are now rapidly becoming cheaper and therefore we can say that the future belongs to these technologies.

I believed that renewable energy will be a great solutions to heal our mother earth and stop or lessen global warming we are experiencing right now. We already abused this earth that's why the nature itself is already demanded the price of what we had done. With these act we can still give our children a better world to live in in the future.

Of course, the entire world will surly depend on renewable energy, fossil fuels produce in oil industries have there own goal and have time frame, even though those fossil fuels are obtained naturally, living there raphinate or waste products without renewal is a great harm to the entire world. Renewable energy is what the world will depend on that's one of the great function of technology. We use technical ways to renew the energy so that we benefit tomorrow.

It's true after all we have to get used to using renewable energy and we have to take advantage of it,
the occurrence of global warming, of course, all of this cannot be separated from greedy human activities,
this is clearly a serious problem for the whole world

The good news is, that the ozone layer is healing, that's what I've read at least. Not sure how accurate it is though. We have abused this year's natural resources already. The pandemic also lead into fewer CO2 emissions, but it was only temporary.

We're way too dependent on fossil fuels, which have adverse effects to the environment, hopefully, this is due to change the new few decades.

We should also look through ourselves, do we care for the environment? Simple actions such as picking trash from the beach, recycling and reducing our vehicle usage can really made a difference, if are widely adopted.

It's sustainable but it's intermittent, you know, some days there's no sun to fuel your solar cells, sometimes the wind isn't strong enough to generate power. But we are slowly getting to making it work 24/7 and 365 days, plus we also have that problem with storage, we need a more efficient batteries and energy storage so the surplus energy that these renewable resources produce doesn't dissipate.

New energy is increasingly difficult to find, if we don't care about renewing energy then we can be sure that the world will experience big problems, maybe the price of energy is so expensive that only the rich can pay, now we must support energy renewal programs so that they can save the future of our children and grandchildren.

I believe that one day humanity will be totally dependent on renewable energy, as fossil fuels are a limited and highly polluting resource. Currently, many sectors already use sources of renewable energy for its production. Sugarcane biomass is just one of the sustainable energy resources ​​from bagasse and straw, being transformed into electricity. Another excellent source of clean energy it is solar energy that, in addition to being silent and clean, has low carbon emissions and is an excellent alternative for homes, establishments and industries. In the world of cryptocurrencies it is no different, the race for sources Renewable energy for bitcoin mining doesn't stop, mainly due to constant attacks from organizations that want to end bitcoin with the excuse that mining destroys the environment, which is not true. A CoinShares Research survey shows that 74.1% of the energy used by bitcoin miners in the world is produced by renewable sources, mainly hydroelectric, solar and wind, that is, in the near future, even bitcoin mining will be fully sustainable.

Shifting to renewable energy will hinder the advancement of the countries that are developing. You will see that the poorest countries today still have oil to extract from their soil. It would be a waste for them to just let this oil be unused when it's worth a lot of money for their people.

They could gradually do it but machines need burning power that wind, thermal and solar energy couldn't provide. How are they going to develop trains all over the parameters of their country if they are not going to be using fossils? It will be unfair for them.

How much of the total energy produced is made from renewable energy resources? I'd say less than 20% or 30% at most. The shift from fossil fuels to renewable sources will take many years and will happen gradually. We won't see much in terms of advancement till 2030, at least.

I believe that energy resources will have to move to renewable ones in the future because the non-renewable ones (obvious from name) finite and they will not be able to sustain us forever. Don't get me wrong I hope it stops today and we move to renewable today, however we know that governments get donations from those big oil companies making it impossible to stop them.

However, reality is that even if they do not stop and they continue to ruin the world as they are, they will still have to stop eventually, many oil companies are still trying to do their renewable parts as well, mainly wind turbines because they cost a lot but then they give you profit forever. Solar is a bit more individual where people start to put it on their roof, and big companies are doing wind turbines as well because everyone knows gas and oil will eventually end one day.

What many people do not understand is that a fast transition is not going to be possible, there is too much money invested in the current technologies that we are using so it is going to take a lot of time before renewable sources of energy become the main source of energy around the world.

However as long as we can implement them and make a more efficient use of our energy then we are going to see improvements on the environment, and once enough time passes then a full transition will be possible, however I think this will take 4 to 5 decades at the soonest.

I agree with the first part, but not with the last. 5 decades is just too far. We don't have enough fossil fuels (including natural gas) to sustain us for that long. The big change needs to come in the next 10-15 years. Energy from renewable sources are getting cheaper with every passing year. I can give you an example. Solar electricity had a break-even price of around $0.40 per KWh just one decades ago. The same stands at $0.08 per KWh. And in the next 10-15 years, we can expect this to go down even further.

It will be the future but we have to solve the problem of intermittence of their generators like no winds for today or the sun is just not shining enough. And another important note is that we also should consider a proper, efficient and cost effective storage for this harvested energy because their surplus are always used for nothing which might be a big money saver if we are able to store them.

The point is that renewable sources of energy makes the whole ecosystem of energy generation a lot simpler, decentralized and since in most countries the main energy provider is the government, it means the state would stop collecting huge amounts of income from this service and many employees who work on the sector right now wouldn't be needed anymore.
I believe that is why there isn't decent investment and effort to improve renewable sources of energy production and adoption. The archaic model most of us have access and currently make use of is profitable for the ones who are on the top, so of course they won't want to change it at all. If there were legit interest from the whole society in renewable energy sources I believe we wouldn't even need to wait more 10 or 15 years to see it going mainstream, as it would be already happening right now.

This is also an important factor, fossil fuels are being rapidly draining in the past few years, I don't think we have that much time. An interesting example can be found through Worldometers.info, showing that at this consumption rate, the oil reserves will have diminished within 47 years(https://www.worldometers.info/oil/). There needs to be a rapid change in the way we work as a society, starting from the simplest of things, such as reducing plastic waste, recycling and so on.

Take a look on Worldometers, again, there are statistics of how much coal, natural gas, oil there's left, while how much of the energy used today is coming from renewable and non-renewable sources.

https://www.worldometers.info/energy/

It's definitely possible and you might say essential that the world eventually transitions to all renewable energy. Fossil fuels like oil are a finite resource as you say, eventually they will run out so we better have a replacement built up to take over or everything will grind to a halt. We are a very wasteful species and have killed off may thousands of different species as we slowly ruin the planet. Even if we do make the switch to renewables fast enough, hopefully we have avoided acidifying the oceans and there are still a diverse array of animal/insect life that is able to live in the inhospitable conditions that we have prepared. Unfortunately people bad estimators so weather conditions might get a lot worse and do a lot of damage in the near future.

Calculating the oil reserves can be a challenging task. Because most of the petroleum deposits that are trapped in remote regions such as Arctic and deep-offshore are not included in the calculation right now. That makes sense, because extracting these deposits is not financially viable. But as technology progresses, it may become possible to extract these deposits at market-rate. Also, in a lot of countries gasoline is being replaced with LPG or CNG. That will reduce the consumption of crude oil and make sure that these deposits last longer.

In the future, I think renewable energy will be used massively by all countries because given the current depletion of fossil energy sources and the use of fossil energy will also have a negative impact on the environment, therefore renewable energy is the right choice to reduce damage environment and prevent global warming.

You may calculate exactly how much we have, or may not and fail doing that but the fact is that there is a finite amount of it and we all know it. Sure most of it is still underground and it will take decades before we run out of petrol, but that doesn't change the fact that no matter what we do, eventually there will be no more oil.

Look at Saudi Arabia, they are buying so many things outside of their nation because they know that one day they will not be able to make profit from just oil and that is why they are trying their best to make as much investment into other stuff as they can. This will allow them to make profit even after all of the oil is over. What we should do however is stop it right away and start investing into renewable energy because we are ruining the whole planet by simply wanting a bit more profit for a few more decades, does it really worth it?

You do have a point, however, we cannot actually predict when and if this is going to happen. There's certainly more petroleum and natural gas (CNG) sources, which we may not acknowledge yet. Despite that, there's a certain need to decrease our dependency on fossil fuels for energy, if you have a quick look on each country, through the sources I provided, the average energy produced from renewable sources is approximately 10-15%

I think renewable energy is just a temporary solution to get rid of fossil energy and nuclear power. Humans will have to find a new form of energy to serve humanity to develop to a higher and more sustainable level. We are hoping for scientific and technical achievements.

I strongly believe that renewable energies are the future especially in terms of cryptocurrencies. As you all know, fossil fuels have been used for cryptocurrency mining for a long time. We are seeing new that renewable energies are starting to be used. And in the future, renewable energies must be used by the majority to have a better environment and better world as a result. Otherwise, there is a really worrying future waiting for people.

Bitcoin mining consumes approximately 0.50% of all electricity consumption worldwide. That's more electricity than the whole of Washington state on a yearly basis. If we also take into account other, Altcoin mining operations, this number is severely larger. It would certainly be more beneficial (And more profitable) if these mining operations were using solar panels, or another form of renewable energy source.

Renewable is future of human life. It is clean. One major concern I have is smogs. We know how harmful it is to humans, the environment and the economy. Renewable energy will definitely improve the air quality in our cities. The pros outweighs the cons when considering switching to clean energy.

I think that renewables energies are definitely the future for us. It is not only crucial for cryptocurrency mining, but also for the future of our world and environment. There are so many human-induced environmental problems now and fossil fuels can be one of the examples for this. We must completely end using this energy source as soon as possible and we must start using green energies directly. Otherwise, we won't have a world which we will be able to live in like always.

- Maybe it's just a way to deal with the temporary dangers of energy sources for the future but as a best way, it seems to be recognized as our future because the scientific world has been pursuing for many years in the research of other energy sources that can replace and serve humanity, the result is still that depletion will be a problem that happens over time. Therefore, renewables are almost hitting the nature of the weak points of energy sources, renewables are also simpler when there are quite a lot of impurities and wastes that can be used as fuel.

There are plenty of ways to create energy, nuclear is one of the most effective, but dangerous nonetheless, it's a practice that should slowly be diminished, for the sake of our safety. As another user mentioned above, there are a variety of renewable sources, which may and probably will not replace fossil fuels in the next upcoming decades, however, our dependency on them must be decreased, in order to sustain them for the future.

If we talk about reducing our dependence on fossil fuels, then this is the same as requiring enormous research and development.  However, I highly doubt it can diminish in a short amount of time.  It takes an extra approach and a very long time to change the people's habits that have taken root.  If fossil materials are replaced, the solution is electricity, but electricity also requires coal for its basic material.

That's true, it is indeed a great idea to produce energy from renewable sources, however I don't think we have the technology to apply it on a large scale, yet. I believe that we'll have positive results the upcoming decades, increasing our renewable sources capacity will also decrease our dependency on fossil fuels, thus, preserving them for an extended period.

I think the technology must already exist but it seems that it is only limited so not all of them can implement it,
I hope that this goal can be achieved because after all by using renewable energy it can protect the earth too

As what we have now, I think that the current products for renewable energy generators are already cheap for an average family so I don't think that the companies would pursue to make an expensive one plus there's a lot of inventions in the renewable energy sector that makes things much cheaper to the point that anyone can provide it.

The tricky point there is the fact that mining uses energy, and yes that is correct their energy consumption is high but they are not the ones that generate that energy at all. They are not asking if it is solar or hydro or wind or oil or whatever, they just use it. It means that it is the problem of energy companies to stop with oil, and work on getting renewable energy everywhere around the world. If they could do that then miners would be using renewable energy as well.

So, the problem is not that miners are using too much energy, it is that they are given the wrong type of energy to begin with. Thankfully world is going more and more green every year, not enough yet, but still greener is a good start.

What form of energy we are talking about, solar energy can be implementing in places where they get ample sunlight and it wont help in countries where there is freezing cold all round the year, but the major problem i see with the solar energy is that the battery technology has not undergone any major changes for decades and they have a life span of 5 to 8 years maximum and even if i want to move to solar energy the amount of money i need to shell out for maintenance and replace batteries every 5 to 8 years will be huge.

The technology is not advanced enough or cheap enough to get a good ROI if you invest in solar for the average consumer. You might have hydroelectric power or windmills used in isolation in some countries if the burden of electricity is small, but larger countries don't have any chance at switching to renewable any time soon, so perhaps the answer is what you mean by "the future."

Nuclear power should be in the near future, though. The main problem with nuclear is what to do with the resulting waste, but it seems the carbon foot print of disposing nuclear waste is lower than that of fossil fuels.

I am in favor of renewable energy sources, but I believe that with the introduction of such technologies, it is also necessary to show common sense and not go to extremes. It is quite unpleasant for me to observe how entire fields in nature are blocked by solar panels, disfiguring landscapes that prevent plants and animals from receiving their portion of sunlight, exactly the same can be said about the aquatic environment. It has also been known for a long time that large hydroelectric power plants change the climate and often not for the better in the vicinity of their construction and down the riverbed. The blades of wind generators kill birds. As for nuclear energy, I would like to say the following: now the technology of fast neutron reactors is being introduced, where spent fuel can again be used as fuel, which should almost completely solve the problem of nuclear waste.

Its possible its just that nothing is as cheap as the cheapest oil coming out of the ground in the middle east which is very easy to refine also.     Massive amounts of power are available from hydro power but it also requires the purchase of turbines of equal size.
   Tidal power is ignored by most who could use it and dont, entire countries can be powered in this way if the investment and decision was made to do so.      This isnt going to be for equator countries but there is a tidal range of 50 feet available between high and low tide that could be used not everywhere but tides are openly available if people wanted to use it.   The total amount of energy being taken from millions of tons of water available every day in this weight transfer is zero at present so its ignorance and apathy mostly fueled by cheap oil.   Solar per unit cost that was $70 decades ago has fallen to 70cents cost now, anywhere with consistent sunlight can choose this route but also it requires batteries so there is always some cost but its possible in every case as an option imo

https://talkimg.com/images/2023/06/12/AffP3.jpeg

Currently, developed countries are interested in energy issues and energy use. They have a preference for renewable energy. The research and application of renewable energy is becoming more frequent. Wind power, solar power, electric cars, tides are things that are being talked about a lot.
In Germany, there is a road installed with solar panels.
Policies of countries to promote renewable energy. In many developed countries, there is a policy to buy back electricity at a higher price than electricity from fossil energy sources. I believe renewable energy is the future of the world, but we also need to acknowledge the important role of fossil energy such as oil, gas, coal... in the marine industry, metallurgy industry, chemistry...

I have heard that some European countries are going to switch to renewable energy sources until 2050. We see successful examples of those which use wind, sun, water and this way they get energy. It will be a really big step for human civilization to start using only renewable energy and I believe that thanks to new technologies and development of science it will happen within time.

That is the aim of the European Union, to have zero net Carbon emissions by 2050. They have three decades, so it should be possible. But right now, there are a lot of countries which are using coal-fired powerplants to generate electricity. Even if they switch to natural gas, there is going to be net emissions of CO₂. One option is to replace thermal powerplants with nuclear ones, but the rise of Green party in countries such as Germany has put a doubt on such moves. Ironically, the Green party is fiercely opposed to nuclear energy, which is one of the cleanest forms of electricity generation (if managed properly).

No one is going to have any problem because of course it's a future but still there are many issues with this which need some good time to solve, and then we can use this all without any interruption because oil and gas is very limited and now really hurting in many countries' economy very badly.

Renewable is also not easy task for many but hopefully as it's working we will be able to have some more flexible things for this because currently its cost is also very high, and we are not sure is this going to work 100% because It's still in developing process I am sure we can go through this and have some better and energetic environment.

A complete switch from fossil fuels to renewable is highly unlikely within 2050, zero emissions may sound ideal but I'm not sure on how it can be achieved. I hope I'm proved wrong, but the time period looks quite small for something so large.

In my opinion, it'll be a success even if fossil fuel usage is reduced by 50%. Renewable sources sound like a panacea, but I'm not exactly sure on how easy and efficient the transition can be.

Renewable energy in the future is predicted that by 2024, solar capacity in the world will grow by 600 gigawatts. Renewable energy is providing affordable electricity across the country and can help stabilize energy prices in the future. Hope it will be successfully done.

In the UK, renewable capacity is expected to increase by 30% by 2024, with a majority of this utilising the country's plentiful offshore wind potential. More specific forecasts for the UK in relation to energy are published annually by the department for Business, Energy and Industrial Strategy (BEIS).

We are heading in that direction, where the government is promoting the utilization of renewable energy sources. It may not be an easy path, but slowly, people are recognizing the benefits of investing into these renewable energy sources like putting up their own solar panels/wind generator at home. Some countries even have their incentives like in Australia - they called renewable power incentives (not only solar) - https://www.energy.gov.au/rebates/renewable-power-incentives. This will encourage people to set-up their own renewable energy source. Not only helping their financials but the environment also.

I have just read the first page of this thread and two posts which I have quoted
hits the nail on the head [above],
and the one below along with pretty much all other posts on the first page and I'm
guessing the vast majority of the other pages fal into what we are being fed by
governments and media.


I couldnt find anything to watch on TV this evening and youtube suggested I might
like > Michael Moore Presents: Planet of the Humans | Full Documentary | Directed by Jeff Gibbs

https://youtu.be/Zk11vI-7czE

. . . and I hated it, such an embarrasing and depressing movie, a worrying movie and
a movie which highlights many lies we are being fed.

Currently renewable energy is running at a loss, the energy used to produce the tools
which are used to create green renewable energy far outweigh the energy created
by those tools. The resources which are used to make solar panels and wind turbines
are stripped from the earth and processed with a massive amount of energy and
fossil fuels.

The movie above literally focuses on everything from Solar, Wind, Hydro and Biomass,
combined with industries and big business and highlights how we are actually accelerating
the problems they are actually telling us the are trying to fix.

Biomass in particular is a massive problem which is not sustainable, the joke is that by using
biomass we are using one of the very few things which cam help the planet, vegitation,
particularly Trees. By using Biomass we are burning biodiversity.

It all just feeds into capitalism and consumerism and the winners are big business, not us.

I voted NO

For electricity generation, now many forms of renewable energy are more cost-effective when compared to the non-renewable sources. Cost of generating solar power and wind power has gone down by 20x or more during the last two decades. But the main issue is not with electricity, but with automobile fuel. This is the problematic area. The conversion of gasoline driven vehicles to EVs are not happening in a big way, because the EVs have a limited range, and they are much more expensive when compared to the gasoline driven vehicles.

Agree to this and there are only few charging station of it and really you cant drive really really long distance. Regarding renewable energy there are a lot of people now a days in their homes buying a solar power light since it could save energy and also lets say that it could make the environment better. I think the future in renewable energy in terms of electricity is really great, but the gasoline powered vehicle is the next problem tho

So when we are driving around in our new electric powered cars carbon
emissions and global warming will be neutralised and the planet will begin to heal
itself?

With more EV's produced the need for electricity  increases, surprise, surprise.
So we produce more solar panels, more turbines, we block more rivers and burn more
trees and gas.

For example Solar panels are made from Quartz and Coal, extracted and transported by
Diesel and melted together in furnaces.

It doesnt make sense, we are consuming more and more of the earths resources in
order to produce renewable clean energy.

The agenda is to sell us more products.

Best thing we can all do is buy land and plant trees (as a start.)

 

That still doesn't solve the issue of affordability. The Tesla Model S costs around $100,000. This is around 3 times the price of a similar automobile which runs on gasoline. Personally I don't afford paying up to 50% more for an EV. But 200%? That doesn't make any sense for me. They need to reduce the cost and make the vehicles more affordable. And for that, they need to dump the current Lithium-Nickel-Cobalt-Aluminium batteries and move towards a battery technology that uses less expensive metals. I am afraid that it may not happen anytime soon.

It is not just about EV or anything, it is both a symbol plus it is a much better car. If it was only EV that you are looking for, then you can get a lot cheaper cars, you can find hybrid for as low as 10-20k, that means there are cars with 80% discount on a tesla model S, and if you would like to, you can buy them, and yes 50% cheaper EV that is a lot better. However tesla is a symbol, just like how iphone was the most expensive phone you could get for a long time, it is getting closer these days but still it is the most expensive one, why? Because it is a symbol and not just the product.

If your aim is only to get an EV then you can do so cheaper but if you want to have a symbol (no not renault) then you could pay more and get a tesla. Plus the fact that it is so much better is a big plus, it literally drives itself, how many EV cars can drive itself on the road?

I doubt that the result from using renewable energy on the environment will be convincing enough to make the world rely on it completely. It's more like a drug everyone has high hope on but once the drug is not working as expected they don't depend on it too as a cure for their problems.

Yes, of course. Renewable energies are very crucial for the environment the most. People must stop using fossil fuels for good and replace them with renewable energy sources. This will help us keep the environment in a good condition in the future too. And these energy sources are very important for cryptocurrencies also. For example, Bitcoin mining was using fossil fuels at a high rate. But this has started to change since miners started using renewable energy sources.

Well.... agree with most parts. I agree that there are cheaper EVs available in the market and over the years, they have become more affordable. But as I said, the only negative point for me is the battery technology. They are still unable to create a battery from cheaper ingredients. Nickel may not be that rare, but the same can't be said about Lithium and Cobalt. The latter is especially in short supply. Right now, the supplies seems to be enough. But Cobalt can create a bottleneck in the future, as the deposits are concentrated in a few high-risk nations such as DR Congo. 

I'm all in for electric vehicles, I mostly like their concept and its benefits, not paying for petrol, they have immense acceleration and so on. However, I don't believe that they are fully developed for mass usage. They are still quite expensive and till a few years ago, Tesla was the largest competitor. The Tesla Model 3 for instance, costs approximately $50-60.000.

During the past few years, more and more EVs are being developed, such as Hyundai, Volkswagen, KIA, Volvo and a few others.

Increased competition should result in these vehicles becoming more affordable. I can see a considerable reduction in the monopoly in high-end EVs that Tesla had, in recent times. Tesla had the advantage that they were the first ones to mass produce EVs, but now other automobile manufacturers seems to have realized that EVs are going to be the next big thing in this sector. And despite the monopoly that Tesla had, they never contributed anything positive to the EV sector. If they had done something useful, then we would be having a much more affordable and reliable battery technology by now.

Tesla used to be the main competitor in the EV sector, that's why their prices were so high as well. On top of that, Tesla had a terrible policy when it came to servicing and salvage vehicles. Despite EVs being a pretty new market, there are already quite a few models, from different companies, that have recently been introduced to the market, reducing the monopoly effect Tesla had on the market.

We do not yet have a reasonable enough way out than to rely on the increasing use of renewable energy sources. I have been interested in solar panels for a long time and see that their cost is constantly falling, and the efficiency is growing. For this, other, cheaper materials and new technologies and inventions are used. It was necessary to switch to renewable energy sources much earlier, now there would be no problems with the environment, climate change and the energy crisis. The corporations that produced oil and gas slowed down this process. The world will now be forced to switch to alternative energy sources. I also think that soon we will see various inventions regarding other energy sources. Of course, all these new sources of energy are the future.

Solar is great, the chart for cost per watt is like a ski jump.  Its fallen so much I hope solar is massively more viable ongoing then it used to be even in fairly northern parts of the world, obviously its been viable in a desert terrain for a while.    Big one I heard is skyscrapers with all the windows able to function as part solar panels, thereby the building becomes justified in its energy usage; really big if true since cities are natural polluters.


I see a few people really disagree with this idea but I do think BTC is useful for remote energy use out of hours and so on it has a purpose not obvious at first site.   I think the simple idea of pumping water up a mountain to a reservoir is superior for storing energy longer term.   Theres a few other ideas but on a base level BTC is finance efficiency not the literal storage of the physical.   These two things arent really separate, its really about timing and peak energy usage being available so yes I think BTC has relevance in its continual demand and ability to be placed almost anywhere.

I agree with you, Solar power is the future and we will see another push in the next 5-10 years. The efficiency of solar power is constantly growing and once we solve the problem of more easy ways to transfer and store energy it will be the main of energy. Building large Solar farms at the best locations on earth with plenty of sunlight and then transferring the energy to unfavourable locations will be the key. Why not take advantage of free energy that is provided by the sun every day? In my country the government is just changing the law, and any new build residential roof needs to have solar panels on top of it in the future. This will transform the energy consumption for the residential sector. As for industry solar power is probably not strong enough and requires other forms of energy. In my opinion Solar and Nuclear power is going to be the future.

Yes the cost of solar panels have greatly reduced over the years and as we can see we now have a lot of devices that can be easily powered by solar. Not only that they are cheap but they are also friendly to the environment.

I think this can encourage more people to switch on solar than to the standard type of electricity. Haven't heard any new inventions related on the renewable energy. Did they run out of idea already? Because there have been a good number of inventions that we saw on the past but I believe that they modify it and they make it more better. Renewable energies are the future because like I said earlier they are more cheaper and more greener.

While solar panels are great and have gotten way cheaper than they used to, in order to have an effect globally, it would require mass adoption, which is quite a procedure for most households. On the other hand, if I had my own house, I'd definitely invest in producing my own energy. Along with an electric car, it would significantly reduce living costs and achieve ROI within a few years.

Renewable energy is a source of energy that we can use once and reuse over time. This renewable energy source is believed to help us in the future.
But, there are various debates about this. I have read some news about this. As far as the idea came after reading it, this is exactly what the future energy system will depend on renewable energy. Because of the growing demand for fossil fuels in this world, the amount of fossil fuels is very small.

But in some cases, the use of renewable energy remains a barrier.  According to many, using renewable energy can cost a lot of money but coronavirus has brought our world to such a stage that many countries are now bankrupt and many people are unemployed. Again, many are not able to rely on renewable energy.

But what is the harm to hope? European countries are now constantly inventing new technologies. Maybe one day the renewable energy of technology will overcome these obstacles and become fully usable for human beings.

In Europe many countries are heavily investing in renewable energy to obtain climate neutrality by the end of this decade. Many countries have already joined and more are going to join.

Kinda old post but I'll just share my opinion. I don't think renewable energy, in its current state, is enough to completely fulfill our current (and growing) energy demands. I'm convinced with the advocacy of switching to nuclear as a gap in the transition from fossil fuel to renewables. If we're mostly concerned about CO2 then it's definitely less polluting than oil or coal. Of course there's the issue of where to dump the waste and the fear of meltdown.

For the renewable, I'm not that hopeful with solar although for home use it is the most accessible (though I'm yet to find someone who was completely switched to solar, they just use it to cut down on their conventional electricity use). I think hydro and geothermal are the most efficient but they are limited by geography.

 
Yeah that's the main barrier. It can require a hefty upfront cost which the people who would benefit the most, the lower income families that have small power usage, can't afford.

The problem right now is that the storage and transmission of it is not easy. It means if you build a huge solar farm somewhere in the middle of nowhere, then you will have a lot of difficulty to store it and sell it to someone 1000kms away from that farm.

If you want to put solar panels on the roof of your house, it works wonders, my friends did it for their summer house and they do not pay a single cent for their electricity, it costed them around 6 years worth of electricity bill, which sounds a lot when you pay it right now, but imagine putting that amount aside every single month after you already have that panel, you would be making a profit, and bills keep going up each year due to inflation, add that in and its even quicker and much more profitable. So right now, individually it is by far the best solution, but as a business it is still quite difficult to handle the storage and transferring part.

For the good of our world, that is what has to be done. I have been seeing the trend of countries that has plans of switching to renewable energy sources before the decade is over. So, I believe that in the next few years to come that renewable energy sources are going to be a huge thing in our world, and a lot of countries will be opting for this source of energy instead of the old ones that we have been using. This would be a way to save our environment from harmful substances,. It is all going to be a gradual process, and it will be achieved.

We don’t know that yet, but the world is taking every opportunity to switch to renewable energy sources. Nowadays you can see a lot of campaigns that are promoting the use of renewable energy sources, and condemning the use of fuel and the rest of other sources that are harmful to the environment. It is like a regular thing these days, and there are also companies now that are more focused on having energy sources that are renewable and not harmful to the environment.

This trend seems to be growing day by day, and as time goes on it’s quite possible that it would become a huge trend and most companies would be switching to it. I don’t think there would be any that would like to be left behind when most others have switched to a better source that doesn’t harm the Environment.

The world is already suffering from an energy crisis, that's why researchers think of renewable energy as our future.
We have already got many benefits of renewable energy, you know, many of us have solar panels in our homes, which is Quiet Useful.

The fuels we use emit large amounts of carbon dioxide, which is extremely harmful to our environment, but the use of renewable energy can protect the earth from excessive carbon dioxide emissions and global warming. That means renewable energy is environmentally friendly.

But the negative side is also worth thinking about, I don't know how much the next world will be able to make good use of renewable energy. Because it is expensive to use and about 90% of the country is suffering from serious debt due to pandemic situations.

Do you think that Crypto coins can promote the usage of renewable energy sources or facilitate similar projects in the future?

We "kind of" know it. How? Well non renewable energy sources will be over eventually, maybe it will take 5 years, maybe 10, maybe 100 but they will be eventually over. By that time world could be gone because of all the horrible way we treat our planet but even if it stays, that means they will be all gone. This results with renewable energy having the only path to go. This is known so companies are already making a good amount of investment into renewable energy. In fact the increase in investment to renewable is bigger than the new investment fossil ones are getting.

So, this math shows that "eventually" renewable energy sources will be our future and current methods will be gone. We also need to realize that energy is something we are lacking a lot, and if we keep on using it like this, only thing that could survive us will be renewable ones.

The bigger problem is that all of those things causes people to pollute the earth as well. If you check the biggest polluters in the world, you will realize that most of them are energy companies, which is a proof that all these oil and gas situations are actually terrible for the world as well. Not only they are taking the limited resources we have in this world, but they are also making the climate problem a big trouble for all of us at the same time.

Maybe it will be too late, or maybe it won't be too late but I am 100% sure that we will end up with a renewable energy solution eventually where everything will be a lot better in the end, may take some time before it happens though.

Climate change is a global problem that we are facing today. This is why the rise of utilizing renewable energy sources is very much encouraged. And this is true, because more and more people are going into the use of solar panels or wind turbine and other renewable energy. Even in construction industry, they are promoting the green construction concept. I believe humanity will indeed find ways how to address this global problem. Because it is on our hands how we want our future to be on this planet.

I recently saw a video from Nas Daily, about the Barakah nuclear plant in the UAE, if I am not mistaken, which is currently producing more than 1/4 of the whole country's electricity demand. Despite having awful examples in the past, Chernobyl, Fukushima and probably a few others, I also believe that their technology has vastly improved, by learning what went wrong during these incidents, and eventually in the future it could potentially be one decent solution against fossil fuels, along with forms of renewable sources, supposing we find a way to process nuclear waste safely.

Does anyone know any Coin which channels a part of the value generated into renewable energy sources?
