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.
So the thermodynamic explanation of the world economy remains the same as it has since the industrial revolution liberated us from reliance mainly on the (renewable) muscles of people, horses, and oxen or the vagaries of (renewable) trade winds. We use the heat of flames to do useful things, such as move stuff around, light and heat our homes, manufacture goods, grow crops with tractors, power the Internet.
The main change in recent years has been that energy is increasingly centrally planned. Instead of a market deciding between fuels, the government picks favorites to subsidize, and then subsidizes the old ones, too, when it finds it has poisoned the market against them. Throughout the Western world energy markets are coerced. The development pipeline, corporate rhetoric, and fuel-market shares are all determined by policy.
This has some perverse consequences. Lobbied by firms such as General Electric, Sylvania, and Philips, governments all over the world forced consumers to give up incandescent light bulbs in favor of expensive compact fluorescent bulbs, ostensibly to save energy. All this achieved was a delay in the voluntary replacement of both by a much more efficient, safe, and reliable form of lighting: LEDs.
