Solar power has quietly overtaken nuclear in the world's electricity mix

A decade ago, nuclear power generated ten times as much electricity as solar. Last year, solar produced 2,778 terawatt-hours worldwide — 13 percent more than nuclear — according to Ember data reported this week. Panels have fallen about 90 percent in price since 2010, capacity has been doubling roughly every three years, and some of the fastest growth is in poorer countries, where cheap solar plus batteries now means energy security that oil and gas never offered. 'Solar is the fastest-growing source of new electricity in human history,' as Ember's Dave Jones puts it — and it happened without a single headline moment, one rooftop and one field at a time.
