The truly deluded reckon that by adding a few giant lithium-ion batteries we’ll soon be running on nothing but sunshine and breezes. Those that (often grudgingly) concede wind and solar’s weather-driven (ie perfectly natural) unreliability, claim that storing wind and solar power when the sun’s up and the wind is blowing, just right, and releasing it when the sun sets or calm weather sets in, is a cinch.
The laws of physics and economics, say otherwise. As Van Snyder details below.
