That's a wrong take of my opinion. It's better to use energy at times of overabundance for something economically useful (money to make the renewable project cheaper = affordable), than to just throw the energy away. If Bitcoin can make renewables more economical, we can stop burning fossil fuels faster. And if Bitcoin causes coal to be replaced with anything, that's a win for the environment too - even if it's a net increase of energy usage and heat, it's still a net decrease of greenhouse gas production which is much more important that reducing energy usage.
