Overall, renewable power plants produced 244 TWh last year compared with 226 TWh in 2021, the Fraunhofer Institute for Solar Energy Systems ISE said on Tuesday.Electricity generation from solar energy grew 19% on the year to about 57.6 TWh in 2022, helped by sunny weather and the 6.1 GW of new solar capacity that was deployed across the country by the end of November.Wind energy was the biggest source of electricity in Germany last year with onshore wind parks generating 98.7 TWh and offshore turbines adding a further 24.8 TWh.At the end of November, the country's installed onshore wind capacity was 58.2 GW while offshore wind reached 8.1 GW.Among conventional energy sources, coal-fired power generation increased for the third year in a row as a result of the energy crisis caused by the war in Ukraine."
