Bitcoin's absolute power consumption isn't at a critical level yet — Bitcoin consumes as much power globally as a single large power plant, and roughly 10% of the world's data centers.

However, I agree that its rapid and consistent growth rate is concerning and can't be ignored.

It's an area I'm really interested in and have been reading a lot about, because most of the news and "analysis" of the issue on both sides has been obnoxiously biased.

I tried to write a balanced summary article of the situation (below). Long-term, Bitcoin's electricity consumption could really go either way i.e. flatten or continue growing indefinitely. There are some causal factors like price that are out of our control, but there are others like the Lightning Network that are both feasible and in our control, and could significantly moderate Bitcoin's electricity consumption.

Well first of all, according to your own blog post, it is not as much power as a single large power plant, but as much power as the single largest power plant in the entire US. And thats just an estimate. It potentially uses twice that amount.

And 10% of the power of all the worlds data centers is absolutely bonkers. That isn't a small number, its spectacularly large.

And all of this for something that has yet to be adopted by 99.9% of the people on the planet.

I think your point about US power plants is a nitpick – The largest power plants in the world are not located in the US, and either way my point still stands because it's meant to be a rough approximation.

Unlike data centers where electricity consumption is directly correlated with internet usage, Bitcoin's electricity consumption is instead directly correlated with its price (which attracts more miners), and is very indirectly correlated with the number of users or transactions.

It's very possible that Bitcoin could be adopted by a significant (e.g. 10% or more) percentage of the world population even as its price remains fairly consistent, which would mean its total electricity consumption would remain fairly consistent as well.

As mining is an economic investment, they want cheap electricity. Cheap electricity is where there is excess that is not being used and would be otherwise wasted. That's why there aren't many large mining operations in NYC but there are in upstate NY near hydro.
