The world's wind and solar projects combined to meet more than a tenth of global electricity demand for the first time in 2022, according to research company BloombergNEF (BNEF). At the same time overall electricity demand, production from coal-fired power plants, and emissions all surged in 2021 as the global economy regained its footing following the Covid-19 pandemic. With nearly 3,000 terawatt-hours of electricity produced, wind and solar accounted for a combined 10.5% of global 2021 generation, BNEF found in its annual Power Transition Trends report. Wind's contribution to the global total rose to 6.8% while solar climbed to 3.7%. Hydro and nuclear projects met just over one-quarter of the world's electricity needs.
