Being German living in France I don't think an absolute comparison like this is telling. The EEG in Germany ( https://de.m.wikipedia.org/wiki/Erneuerbare-Energien-Gesetz) fosters development of alternative energy sources at the real cost of guaranteed purchasing prices. A good investment (see adoption https://de.m.wikipedia.org/wiki/Photovoltaik_in_Deutschland) but borne by all through increased electricity costs. I never liked the price hikes but I do think it will spur further innovation in network anf storage while here in France I pay more for access than consumption and rent from owners not interested in changing windows to anything resembling insulation.
