Wind & Solor Electricity Record in Germany




A short article in Mainzer Allgemeine Zeitung caught my attention today: on a Thursday in April wind generators and solar collectors achieved a record in amount of electricity produced: more than 50 % of the demand in Germany for several hours = 35.900 mega watts, the equivalence of 26 nuclear power plants.
Amazing ! I knew that alternate energy sources are gaining momentum but this demonstrates nicely the true dimension of it and what we have achieved meanwhile. The price of course: wind generators everywhere.
The average contribution of alternate ( renewable ) energy sources in Germany is 23 % according to this German Wikipedia article.

That is fantastic! The US needs more but the stupid government....

Great accomplishment for Germany. I wish the US had listened to Ross Perot and done a comparable thing -- although it appears he mostly wanted to sell natural gas and equipment for it, with wind (I don't remember him advocating more use of solar) as a future plan.

If solar and wind provides 23% of power on average, and 50% at peak output, then presumably it is effective about half the time. According to that it would make sense to double current capacity, if that is feasible, so that it would pull essentially the whole load when the wind is blowing in the daytime. That suggests half of the power would be hydro, nuclear, or fossil fuel based.

That is a very crude estimate. Perhaps you can get over 50% average utilization, assuming either sun power or wind power is available most of the time. If you overbuilt capacity, some of the excess might be used to pump water up hill, extract hydrogen, or charge batteries.
