Bitcoin is now consuming 1% of the world's electricity. Is that sustainable?

[Dondisimo]

Bitcoin does consume enough energy for its production, but it seems to me that in the context of total energy consumption worldwide it is just a drop in the ocean. So I don't think this is a serious problem that we have to deal with. In addition, bitcoin mining will not last forever due to its limited amount.

That is not true. Bitcoin mining is an integral part of Bitcoin. It will continue forever, even after the subsidy goes to 0.

Bitcoin consumes a lot of energy for mining, you can not argue with that. But if you are really worried about this, then you should be reassured by the idea that bitcoin mining is not infinite, so sooner or later it will stop.

Consumption of electricity is very large in the use of bitcoin, especially mining, as evidence that bitcoin is one of the most attractive income for many people.
Advanced business is synonymous with large electricity consumption, and it is an attraction for energy investors to develop renewable technology which means saving the earth from energy shortages by recycling very positively.

The guy above you means that mining wont last because the supply of btc is only limited to 21 million  but you are right mate even if the supply runs out mining wont still end because btc will still circulate  due to the reasons that people constantly buy and sell a btc  .

Btc itself isnt also consuming electricity . people only uses electricity when they turn on their gadgets and process a transactions  , as well as mining  .

Not to forget most of the mining farm concentrate on the same country, I think the consumption per capita will be vastly biased too.

For as long as the means of achieving something good does not weigh more than what good we can get out of it, then it can still be considered bad. For what use would it be if we will in the end be part of our own destruction? So there should be some other way to do things around. Perhaps some solutions with using bitcoin can be implemented so as to minimize the use of electrical power. Humans are intelligent and I believe we can solve this problem in the future.

When Bitcoin hits the coin limit, which won't be for a long time, mining will still be necessary to process and secure new blocks of transactions. Unless they switch to Proof of Stake, which has a host of issues, there is no viable alternative. If Bitcoin isn't popular enough to generate fees comparable to what current miners get in rewards, that coin limit will need to be increased.

those are estimated data, no solid facts, I seriously doubt those data.
