--They hold the promise of replacing it... It could be done. If major nations treated it as a priority project with research, subsidies and carrot & stick methods. Unfortunately I don't think they will.... until it is too late. We'll probably spend more on Mars than on environment.

You're merely pointing out we always need intelligent decisions. Solar makes a lot of economic sense in the Mohave desert region of eastern Kern County California where DWP and 8minute are completing a a sprawling complex of solar panels and lithium-ion batteries. The Mojave will provide 6% to 7% of L.A.'s annual electricity needs and has enough battery capacity to pump stored solar energy into the grid for four hours each night - at a delivered cost of 3.3 cents per KWH ! But Los Angeles also needs consistent electricity after the four hour batteries have run down, and that's provided primarily by natural gas fired electric plants. And there's a lot of places where this project would be tremendously too costly, mostly where there's not sufficient consistent sun. . Current solar panels perform best in clear cold climates, such as mountainous regions of Switzerland above the cloud cover. They just need to be cleared of snow. The Mohave project is less productive because it's too hot, but it's more productive because it received sun more consistently. Large portions of the world, like most of China, experience too much cloud cover to make solar economic currently. Up to a point, cloud cover scatters the light which makes solar panels which can't move more efficient. But as the cloud cover increases, the power output drops off dramatically.
