Germany renewables vs. demand

Cyril R. sums up German energy policy in a three sentence comment on John Morgan’s wonderful Catch-22 of Energy Storage:

Capacity factor of solar PV in Germany is 10%. Wind in Germany is around 16%.

Electricity demand in Germany peaks in winter, when the capacity factor of solar ranges from 0% to 3%.

These energy sources aren’t there most of the time, and certainly not when they’re needed most which is in the evening and winter.
