But your baseload has to be the same as your entire solar + wind production until electricity storage has been solved so why build both solution when you can build only one. I say this often but Germany spent 600 billion euros on wind and solar since 2000. They would have spent this on building nuclear plants and not closing the ones they already had and would have 100% co2 free and cheapest electricity on the planet. There is a difference between theory and practice. Now we are screwed because we lack energy and building nuclear plants will take minimum 10 years so in the mean time we burn gas and coal for baseload and add more solar/wind. At 40% renewables, 11% nuclear and the rest fossil. And that's just for electricity. So optimistically another 800-1000 billion euros to go? Then 2 times that to replace use of fossil fuel beyond electricity?

It's a single market so every country basically has to follow the same set of rules. For example the EU commission/parliament will come up with a directive and every country has to implement it. Not much different from one country parliament voting a law and everyone in the country has to follow it excepted here they put that particular law in place to follow the EU directive. That's a reason why people don't like the EU because it's something not decided by the government they've elected in their country and politicians of the countries are quick to blame the EU when something doesn't go right because it's much easier to blame someone else than yourself.

I think your theory about the wealthy is a bit far fetched. The wealthy that has a business has lost/is losing a lot and still some of those voted for Brexit. It is more about ideology than common sense. One of the main reason is that people can't stand the fact some rules decided by non English people apply to them. A mistake from the EU commission is to meddle in too many things that infringe on the culture of a particular country. This problem of "ideology" vs fact or common sense is becoming quite tiresome as it applies to so many things these days. For example in the energy sector which is now costing us greatly...
