"A remarkable study from Oxford scientists published in 2021 makes clear that solar and wind power (and the batteries to store that power when the sun sets or the wind drops) are firmly set on what economists call “learning curves.” That is, the more you build them out, the better you get at doing it, and so the price drops. At the moment, when solar installations double, the price drops by a third." - Bill McKibben on #cleanenergy economics. https://www.rollingstone.com/politics/politics-features/how-to-tackle-climate-change-math-bill-mckibben-1234691661/
