That’s the biggest fly in the ointment. You still have to have full backup coal/gas/nuke-powered generating capacity for when the sun isn’t shining or the wind blowing.
When one adds the fact that said generating plants can’t be switched on or off like a lightbulb but must always be running at a certain capacity the full insanity of “renewable” energy becomes readily apparent to even those of us from Rio Linda.
I have a friend that works in residential solar in California. He said the cost of residential-on the grid (no batteries) solar was still 20 cents per kilowatt hour meaning that it only made financial sense in certain California markets after considering subsidies.
Show me a coal plant that costs 7.5 cents/KwH to run, and I’ll show you a coal plant that won’t be in business for very long. Most bulk producers/retailers aren’t going to buy at $75/MW. At most, you’ll be lucky to get $27-30/MW on a long-term contract.
