### Any situation where you use solar to produce liquid fuels will have
atrociously low efficiency. We can almost completely replace nuclear and
fossil energy with a much smaller amount of solar and wind electricity if
it is used directly, although we would need a lot of batteries, well over
30 TWh for the USA. See Tony Seba's presentation:
