Alex Epstein: ‘Solar and wind aren’t real power sources, they’re intermittent fuel-savers’ – ‘Usually at great expense’

As a recent week of winter weather illustrated, solar and wind don’t replace reliable power sources—they just save them fuel, usually at great expense.
We’re bombarded with supposed examples of solar/wind rapidly and cheaply replacing fossil fuel power: rapid rises in solar/wind
“capacity”
or
“generation”
; solar/wind
credited
for supplying most of a day’s electricity; stats claiming solar/wind is now
cheaper
than fossil fuels.
Advocates of solar and wind replacing fossil fuel power downplay the obvious, glaring problem that the grid requires electricity on-demand and that weather-determined, intermittent solar and wind can provide nothing resembling that. They either don’t mention intermittency or claim it’s easily addressed.
Take Elon Musk. He posts incessantly about solar replacing fossil fuels, and the vast majority of the time he doesn’t mention the intermittency at all!
When he does he treats it as trivial
, e.g., addressable by just storing excess daytime power in batteries and deploying it at night.
