Second.
As long as somebody in this world consumes coal, you burning free green energy doesn't make things right.
Because if you would stop, then the energy consumed by you would be redirected to the one burning coal energy, and the coal power plant will be shut down....

I concede that my comparison of the energy consumption of the US military to the
energy consumption of Bitcoin mining is somewhat flawed, because they are not directly comparable. However,
I simply wanted to show that there are still many things that are destructive instead of constructive that consume
more energy than Bitcoin mining.

I strongly disagree with the statement in the quote. E.g. if a BTC mining company uses renewable energy
from hydro power in Iceland there is no way that the energy would be redirected to a country that is burning
coal energy if the mining company would stop mining. This is simply completely uneconomical due to the location of Iceland.
On the other hand Bitcoin mining is possible from any place on Earth with an internet connection and therefore it
is a great use of renewable energy that is abundant in countries like Iceland or Canada (countries like Norway would
be great, too, but energy prices are too high there).

You see, you're again missing the point, and you treat bitcoin related activities in a special way.

Miners can move from China to Iceland to mine with green energy but other industries are not allowed!!!!
There are 4 aluminium smelters in Iceland (big ones), and 20x more in China burning coal.
Why not move those there?

You just need an internet connection?
Oh, let's have datacenters there.

And you gave one example, probably the only in a world where we have an island that is too far away to connect via a cable..........for now Tongue

Bitcoin is not perfect, nor is the PoW.
