#1 The biggest issue in the use of solar and wind generators is energy storage. Most energy storage on the large grids is now hydro: pump water into a reservoir and release it when needed to peak. The problem is that wind and solar power are often independent of peak power demand. So interfacing them with a synchronized grid is problematic.
The Green Idjits™ never think of this, so when they put the load on the grid, everything works fine until the wind suddenly quits. So the real issue with the technology, aside from its cost, is the lack of economic energy storage.
I have a solar array that feeds a 24 volt DC battery bank. It is great for a household. A generator backs things up if solar cannot keep up. Scaling up is the problem. Too bad governments don't think it through before they spend. At least the O admin and China have something in common....

#2 I was talking to a friend who had been in India fairly recently and he told me that the power is on a few hours two times a day. That it is normal day to day in India. Seems the power system is very antiquated. Wall to wall humanity. Gracious people.

#3 A lot of the 'idiocy' is, I'm convinced, on purpose.
In Germany they acted in a manner prejudicial to the continued operation of coal plants, just like here.
So their power system is increasingly wind and solar, with natural gas plants operated as peaking plants, which are much less efficient and profitable than baseline plants. With regulated prices they can charge. And finally, they have to buy their natural gas from the "former" SU, at prices indexed to the price of oil.
What's the result? The new selling point, "Solar is more profitable than fossil fuels!" It's just a stepping point to the next lie.

#4 IMO "post-US" wannabe Rising China's focii is rapid progressive national modernization under the banner of "Socialism wid Chinese Characteristics" - any "green tech(s)" is likely more coincidence than intentional, until China learns the techs + moves on to the next, higher-level method.
