From what i have seen in CA the wind turbines are going more than not. but i understand your point. Solar on the other hand is getting bigger every year. I know folks that work for a large solar company that works with the large elec companies on the east coast and they are not slowing down on solar installs.. (the lack of sunspots making dramatic effect on solar is fake news by the way) As long as the sun shines solar works..

Now is that all the time?? NO.. clouds rains, snow etc can reduce the output of solar and the need for "regular" power plants still exist. In my area of NC a lot of the older coal power plants have been torn down and rebuilt powered by clean Nat Gas. Yes there are still coal fired plants around as it take time and money to replace the aging plants.
Its too bad in the 80's the environmental wacko were successful in making Nuclear energy the bad guy.. by and large NP is the cleanest and safest form of power generation next to hydo but you gotta dam up rivers, flood large quantities of land which is not good thing for the folks living in the area.
LNG is also used in OTR tractors which is easier to install, maintain and less costly to operate.
