For me this tells that we as a species are still horrible at producing electricity in an environmentally balanced way. Especially stuff that's on the grid (like stationary computers) should be easy to run on regenerative energy and as Bitcoin is a global currency, it should not be a problem to do so 24/7 (the sun always shines somewhere). On a related note: why is fusion still 50 years away? Nobody seems to put proportional effort in that sector.

ps: I think a satellite that is dedicated to compute Bitcoin with solar energy (no atmosphere/night to bother out there) would be awesome!
