Skepticism is important, but the evidence so far proves out we have a long way to go with the "easy" parts of decarbonizing until we have to solve the last "hard" parts. Capital and cashflows saved on fossil fuels from the easy parts can be directed towards the hard parts when that time comes. Enough sunlight hits the Earth every 30 minutes to power humanity for a year; it's a capture, transfer, and orchestration story broadly speaking. We are bound mostly by the laws of physics.
