> I’m incredibly depressed about renewables. They’re a dead end technology for a civilization in decline
Solar could supply civilization with more energy than fission or fusion (in manmade reactors) ever could. The Sun will produce orders of magnitude more energy than totally fusing all the deuterium or fissioning all the uranium and thorium in the solar system could provide. Far from being a sign of a civilization in decline, the triumph of renewables would be a signpost on the way to becoming a Kardashev 2 civilization that can fully exploit the energy resources of the solar system.
