Just in terms of economics, the demand for energy is elastic and even if we built out enough renewable energy to completely replace our non-renewable sources at today's usage and prices, people would just use twice as much energy. It's not going to be a matter of just building cheap renewable energy, it's going to be a matter of _banning non-renewable energy_ or at least taxing it significantly. There's not a maximum amount of energy per person that people will put to use. If you create more energy sources, we're going to use all of it. It doesn't have to do with AI or Cryptocurrency or cars or farming, or name any other use case that anybody in the world thinks its wasteful or shouldn't be allowed to use energy. If you ban AI from using fossil fuels, they'll switch to using renewable energy and some other technology will switch to fossil fuels. The only solution to ending the use of fossil fuels is banning the use of fossil fuels entirely. Technology will never do it.
