But still not quickly enough to offset the use of fossil fuels
GLOBAL ENERGY demand tumbled by 4% in 2020, as flights were grounded, factories idled and commuters locked down at home. One part of the world’s electricity markets, however, continued to grow. Renewable-energy generation grew at its fastest rate in two decades, according to a new report by the International Energy Agency (IEA), an intergovernmental forecaster. New renewable-energy capacity grew by 45% last year, adding an extra 280GW to the world supply—more than the entire energy-generation capacity of Germany.
