The Folly of Renewable Energy

If you judge by the images used to illustrate reports about energy, the world now runs mainly on wind and solar power. It comes as a shock to look up the numbers. In 2019 wind and solar between them supplied just 1.5 percent of the world’s energy consumption. Hydro supplied 2.6 percent, nuclear 1.7 percent, and all the rest — 94 percent — came from burning things: coal, oil, gas, wood, and biofuels.

As Mark Twain might say, reports of an energy transition away from combustion as a source of energy are greatly exaggerated. True, carbon-dioxide emissions are rising more slowly than energy consumption, but that is mainly because gas is displacing coal. The rise of renewables has so far not even compensated for the recent decline of nuclear — a decline renewables have contributed to causing because intermittent renewable energy hits the profitability of nuclear power hardest. Nuclear cannot be easily switched on and off.
