In what way was the energiewwende disastrous, give actual numbers.

German electricity production is increasingly dominated by renewables, in the first quarter of 2025 (which had unfavourable weather conditions) 46.9% of electricity was produced by renewables (mostly wind). Coal and gas has been declining steadily and Germany regularly exports electricity to nuclear focused France. Currently on average Germany is a net importer from France, but that does mean little because of the way cross border trade is an integral part of the European grid (note that Germany also is a net importer from Denmark whos grid is largely wind based).

So to me that sounds like a success story.
