Being predictable doesn't really matter. Denmark had a great summer in 2018, that meant the wind didn't blow which means they had to import energy from Germany.

Being predictable doesn't really matter. Denmark had a great summer in 2018, that meant the wind didn't blow which means they had to import energy from Germany. Germany has plenty of solar yet they ended up using coal to provide that energy. The weather was amazing in Germany too yet they didn't actually provide Denmark with solar energy. I don't think you done any serious research into this to be quite honest. Then there is capacity factor wich is a whole other problem (look it up) To claim that coal isn't economically sustainable is absurd. It's more or less the cheapest we have. With regards to China thats 5% electricity NOT energy. Again I don't believe you actually did any fundamental research here or you wouldn't throw out these numbers that does not support your position.
