Are Renewable Energy sources the future?

[Anguwa]

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.

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.

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.

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'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.

[sana54210]

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 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.

[blckhawk]

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.

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?

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.

[jamkesmas]

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%

[wack slacker]

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.
