A FEW YEARS ago renewables were having their moment in the sun (and wind). Rock-bottom interest rates lowered the cost of clean power, which is expensive to deploy but runs on sun and wind that come free of charge. The price of solar panels and wind turbines fell as technologies matured and manufacturers gained scale. These developments brought the levelised cost of electricity (LCoE)—which accounts for capital and operating expenditures per unit of energy—for solar, onshore wind and offshore wind down by 87%, 64% and 55%, respectively, between 2010 and 2020 (see chart 1). Clean energy became competitive with dirty alternatives, and was snapped up
