Why does generation spike in the Summer and not the Winter when presumably it would be in higher demand?

So oil is not used to generate electricity?

Disappointing to see coal hasn’t gone down too much

Why is coal the only source that has a prominent second peak in December? On gas, it’s just a blip. I don’t think we’re using THAT many Christmas lights, are we?

Little reminder that, by FAR, coal is the biggest co2 emitter per kWh of electricity produced. It’s urgent to reduce its use if we want the planet to stay habitable in the following century. And we can see it’s not really happening. Surely we produce more renewable energy but it’s just ADDING UP to coal and gas, and not really replacing it.

I’m surprised there is no difference of summer or winter for wind/solar – or is it really the nominal capacity and not the actual produced energy?
In Finland wind produces significantly more during winter, roughly twice more! That should be visible, unless the combined solar+wind compensates this effect away as solar produces more during summer.
