Turiel makes some very strong arguments in the interview. I’ll have to keep an eye out for his book.

As for the quote in the headline, I would say that we should take for granted that we will need to completely replace fossil fueled power sources — Turiel would appear to agree given the reductions of electric power usage he proposes. What is questionable is the systemic willingness to make that transition in a timely fashion.

There are too large financial interests in continuing using fossil fuels to make the change until they are entirely depleted. And the inconvience of the developed world’s middle classes to decrease their energy consumption is too hard a political sell for any populist centrist leader to implement or even propose.
