> Wind and solar existed in the 70s as well.

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...

Now they cost 5.9¢ per peak watt: https://www.solarserver.de/photovoltaik-preis-pv-modul-preis...

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.
