Since it's a common mistake when discussing cryptocurrency energy use, I should point out that it's really only Bitcoin specifically that uses significant amounts of electricity these days. Most other cryptocurrencies have switched to proof of stake systems, which uses negligible energy.

Also over half is used by green energy already and will continue to grow

There is a caveat to this. It’s been a few years since I read the article, but oftentimes the reason Bitcoin miners run on renewables is because they set up shop in places that have established local cheap electricity.

The example in the article was a town with ideal geography for hydro power, to the point electricity was cheap enough to sell it to the next town over. Crypto-miners set up in the first town and quickly began using more power, driving up the cost and eventually causing serious issues for the second town as there wasn’t enough electricity leftover to send their way anymore.

I'm no fan of Bitcoin, but often the energy they use from hydro plants is energy that would literally be wasted otherwise. A hydro dam can't control how much water is entering the reservoir, so if there's more water entering the reservoir than is needed to generate electricity for the current demand then the dam will need to just throw the extra water away. Trying to transmit the electricty to remote markets can be an alternative, but that costs resources too and isn't always practical.
