If I need 100GW of coal power at 5% of capacity, can I build only 5% of the coal plants? Will the coal plants have only 5% the running cost?
This is the problem of intermittent power sources, they end up requiring almost the same amount of conventional backup energy sources as if they didn't exist in the first place, so from an economic point of view they're a terrible choice because they're by no means cheap either.
