Please stop confusing WHATS and WHYS.
In fact, Germany is already [what] cutting back on solar subsidies because they finally realized [why] how much it was costing them.
What: yes we are changing the way how we subsidize it.
Why: because the industry ... and that includes all: production of panels, installing, providing of power, distribution, consumption ... is now mature. The subsidizes of the last decades established a mature industry. So we now change subsidizing to niche situations or for house owners who simply where sceptic and late.
FFS ... get INFORMATIONS instead of drawing half assed conclusions.
Solar's intermittent requires it to ride on the backs of other power sources to be feasible at all.
No it does not. At night when the sun does not shine ... we use how much power from peak? Hu? You don't know? ... so for fuck sake get a clue. At day Solar does not need to "to ride on the backs" of other power sources: because that sources are already there!!! And at night: we simply don't need them: a) because "they are already there" and b) they are shut down to the level where they are kept warm, because we don't need them either.
We are not in the US where a City like NYC has the same power demand night and day. The power demand of a german city at night is not even 50% of day time.
Your whole ideas about renewables, and I told you that 100 times now, are outdated and off world and have nothing to do with the power production/consumption in your country. Get it or simply stop arguing.
Stop using Germany as argument for your US problems. Everything, and I mean that quite literally, in Germany is different than in the US.
Germany will likely over the next decades install enough Solar power to provide about 30% of the day time load. The rest will be wind and biomass and water.
