Time is fast running out. The world’s affluent nations, with their abundant greenhouse emissions, have to finally drag themselves across the starting line and begin phasing out fossil fuels at the accelerated pace that the climate emergency demands. And if they can manage to do that, they clearly will need to quickly build up wind and solar electric capacity to partially compensate for the shrinkage of oil, gas, and coal supplies while addressing the prospect of energy shortages by securing production of essential goods and services for everyone.

Unfortunately, mainstream climate visions have strayed far from confronting the existential necessity to banish fossil fuels. They simply assume that the buildup of renewable energy will automatically chase fossil fuels out of our lives and fully replace them, watt for watt and Btu for Btu. These visions hold out the promise of a world in which a pristine, Sun-powered economy fulfills any and all of our material desires far into the future—a delicious, guilt-free cornucopia. But the green-growth promise is a mirage, and the realities of a high-production, wind- and solar-powered world will be much less tasty.

Any industrial installation, including solar and wind farms, profoundly disrupts the landscape on which it sits. If it were possible to fully satisfy the bloated energy appetites of affluent nation by covering hundreds of millions or billions of acres of the Earth’s surface with power-harvesting hardware, the result would be irreparable ecological damage.
