On July 25, Germany set a new national record for renewable energy by meeting 78% of the day’s electricity demand with renewables, exceeding the previous record of 74% set in May of 2014. A stormy day across northern Europe combined with sunny conditions in southern Germany led to the new record.
Morris writes that most of Germany’s wind turbines are installed in the north and most of its solar panels are in the south. If the figures hold, it will turn out that wind and solar generated 40.65 gigawatts (GW) of power on July 25. When this is combined with other forms of renewables, including 4.85 GW from biomass and 2.4 GW from hydropower, the total reaches 47.9 GW of renewable power, occurring at a time when peak power demand was 61.1 GW on Saturday afternoon. To bolster his analysis, Morris points to early figures from Agora Energiewende, a Germany energy policy firm, that have renewables making up 79 percent of domestic power consumption that day.
