When your energy mix is biased towards wind and solar, the market price for energy fluctuates with the weather, basically. So when there's a lot of wind in an area, then energy is cheap (and the wind farms lose money.) When there's no wind, energy becomes expensive and the wind farms lose money.

This means that base power generation from nuclear also loses money when there's a lot of wind, and that coal power is needed when there isn't any [wind.] So we all pay more _and_ destroy the environment more.

When there's no wind in Germany, they buy from the energy market, driving up prices all the way up to what Coal and Oil power generation costs (which is expensive and terrible), since that is the competition. And since everyone pays market prices, we all suffer from Germany's lack of nuclear. (And ours.)

In a sense: Germany has socialised their energy production.

If I was conspiratorical, I would say that Russia played Germany like a fiddle in this regard. Cancel your nuclear so that you have to buy gas for energy production. And here we are.

Thank you Sweden and Germany.
