“As occurred with nuclear and other technologies, renewable technologies might face their own unique set of challenges that eventually slow their deployment.”
…like the need for intercontinental super HVDC grids and phantasmagorical hydro power output?
I agree that humility is all important. Nobody is always right. But what are the unique sets of challenges stopping conventional nuclear, other than successful antinuclear fear mongering, and who believes that the same propaganda won’t be applied to any new nuclear technology?
