Correct me if I'm wrong, but this seems like a problem that can't be corrected, either. Decreasing energy use means doing fewer calculations (and a few people here have mentioned PoS). If I'm running a multi million dollar cryptocurrency farm, it's against my interests to support a system that's less computationally intensive. The whole point of investing in powerful GPUs is to crunch numbers harder. If the community comes along and says "we're switching to this thing that doesn't need your beefy energy-guzzling hardware" these miners are going to do whatever they can to make sure their investment is still maximally beneficial. Nobody is going to say "Well it was fun while it lasted!" and throw millions of dollars of hardware in the trash.
