The following graphs show: 1) Installed net power generation capacity in Germany 2002–2016; 2) Gross power production in Germany 1990–2015 by source; and 3) German power import/export 1990–2015.
Note that since 2011, the capacity of nonrenewable sources has not decreased. The slight decrease in nuclear was made up for by an increase in coal.
Electricity production from coal and natural gas has hardly decreased, even with the substantial increase of production from renewables.
Since 2002, when the share of electricity production from renewables approached 10%, overproduction steadily increased. In other words, electricity production from renewables – which does not follow actual demand and in the case of wind is highly variable – was mostly exported into the larger regional grid when it could no longer be absorbed by the domestic grid.
