It’s probably a bad idea for other reasons, but it’s one way to reduce the environmental impact of PoW
For example, drop some solar panels and miners in the middle of the desert and immediately start generating profit. Use the profit to deploy more solar panels and build out transmission lines. You can do this piecemeal at low initial investment to feel out an energy source without committing billions of dollars to build out.
I'm not aware of anyone who's done major operations like this, but with the profitability of mining so absurdly high right now plus scrutiny on using dirty energy sources, I wouldn't be surprised if it starts. Access to mining ASICs is likely the key bottleneck.
This is the story used to explain part of the reason so much mining is in China. They built out a ton of hydroelectric dams over the decades that have been underutilized due to lack of infrastructure. Miners came in for the unused electricity and brought in a ton of money to the area.
