Re: I've been pointing this out for years.
The wind doesn't stop at night. Nor does hydro-electric power, pumped storage power, and various other forms of renewable energy. Obviously.
Completely agree, however pumped storage is a rounding error on a rounding error of power provision. Hydro we could, and possibly should, do more with. Biogas from food waste is another reasonable possibility to help with load.
The further through time we go the better the technology gets, so really avoiding peak oil and CO2 emissions is nothing more than a play for time.
