Germany hit a new high in renewable energy generation last week.
Thanks to a sunny and windy day, at one point around 1pm the country’s solar, wind, hydro and biomass plants were supplying about 55 GW of the 63 GW being consumed, or 87%.
Power prices actually went negative for several hours, meaning commercial customers were being paid to consume electricity.
Last year the average renewable mix was 33%, reports Agora Energiewende, a German clean energy think tank. New wind power coming online should push that even higher.
“We have a greater share of renewable energy every year,” said Christoph Podewils of Agora. “The power system adapted to this quite nicely. This day shows again that a system with large amounts of renewable energy works fine.”
Critics have argued that because of the daily peaks and troughs of renewable energy — as the sun goes in and out and winds rise and fall — it will always have only a niche role in supplying power to major economies. But that’s looking less and less likely.
Germany plans to hit 100% renewable energy by 2050, and Denmark’s wind turbines already at some points generate more electricity than the country consumes, exporting the surplus to Germany, Norway and Sweden.
