German Green Energy

Germany installed lots of solar power in recent years, but had very high electricity costs, even before the current energy crisis. The cost was about 2x the US average. Much of that cost is taxes, which are used to subsidize renewable energy. Other EU countries follow a similar strategy.

Solar provides about 10% of the electricity demand in Germany. Of course, solar power is only available sometimes, and Germany is far north. Berlin is at the same latitude as Edmonton, Alberta. There's currently no cheap energy storage system.

It's probably feasible to power entire EU countries with "renewables", but it might cost a lot, which also means industry can't compete with lower energy cost countries.

Canada and Germany recently signed a deal for green "hydrogen", really ammonia, from Canadian wind farm ammonia plants. Canada has a large surplus of natural gas, but no LNG facilities.

Some western countries are hobbled by climate policy and green policies. I don't see how it continues.
