Humanity’s failure to avert the crisis of a warming climate is sometimes framed as a grand technological problem: For centuries, countries relied on fossil fuels to industrialize their economies and generate wealth, and it was only in recent years that alternative ways of powering a society, like solar and wind energy, became viable. But when it comes to electricity, at least, that story isn’t true. Today, the United States gets 60 percent of its electricity from fossil fuels and just 20 percent from renewables.
