The options in the '70s were much different from those of today. And for France specifically what they have underground (lots of uranium, no oil, no gas & no coal) strongly suggested exactly one way forward.
They’re at ~60% total power from renewables in 2025, and increasing every quarter. I’d say they’re doing pretty well! The coal is unfortunate, but was due to the Ukraine war and gas situation.
This is basically nonsense to the extent that it is becoming difficult to extend the presumption of good faith to you. In the 70s solar panels cost US$25+ per peak watt, in 02021-adjusted dollars: https://en.wikipedia.org/wiki/Solar_energy#/media/File:Solar...
Installing a gigawatt of solar power generation capacity for US$25 billion is in no way comparable to installing a gigawatt of solar power generation capacity for US$59 million.
Wind power has experienced a similar but less extreme cost decline.
