Interesting. I track power generation for the UK using a real-time site: https://www.gridwatch.templar.co.uk/
There is a similar site for the US but I cannot find one for Germany. Does anybody have a link?
One other point. I was going to post this article on Facebook, but a message came up saying that the information was not accurate - notably the dramatic photo of the solar panels covered with snow came from Russia not Germany and the message stated that renewable energy production in Germany had not collapsed during the intensely cold period. Unfortunately I could find no way of resolving these diametrically opposed views without the real time electricity generation data.
And they ate saying similar to the Texas diabolical!
