So it matters when wind is providing 20%, but it doesn't matter when it's providing 100%. Thus, even though coal use is at a historic low, it's actually increasing, and in other news water is dry and grass is red.

Of course. Because when there's no electricity, there's no electricity.

You pretend this is a contradiction when it's not. Germany has just shut down its last reactors. So yes, the usage of coal will increase because when renewable generation is low you still need to provide electricity. Guess what provides that electricity.
