Look at Germany, California and the worst case secenario in South Australia where they are constantly on the edge of a brown out all summer long due to installing a substantial percentage of wind and prematurely retiring some of the thermal generation. They are unfortunately now stuck with the most volatile wholesale pricing in the world with pricing sometims as high as $2,000/ MWh.

Rebuildable electricity is only cheaper on paper. When you look at the real world effects, it is always more expensive.

But whatever solar we can build out will be much better than nothing in 100 years.

The conventional power generation is priced beyond the entire GDP of the nation.It's just that the true 'cost' has never been included in the 'price'.
The renewables are,in the long-run,the cheapest energy sources we've known.
