No. Those are all correct.
Whirlygigs pose significant threats to the environment in a few ways:
It's nearly impossible to recycle the blades when they break or the rest of the system wears out.
The lubricants used are some of the most toxic substances that are "out in the wild" these days, and are acutely toxic, so, when the gear box leaks, you have that stuff in your water or soil.
Many designs NEED GRID POWER TO FUNCTION! this means that if the grid goes down, they need to have a generator to run or they can't output any power on their own.
The baseline power issue is very hard to overcome without massive energy storage systems. If you aren't in an area that is conducive to pumped hydro, there are not very many ways to store the surplus energy that is typically generated by solar and wind. California has this issue. It's wasteful in different ways. It can destabilize the grid to have too much power input.
China, India, and Japan can't afford to go green if they want to keep expanding their industrial capabilites. China and India know that coal is the cheapest way to generate power, currently. Japan has been trying to eliminate nuclear for decades.
I don't know much about Korea in this context.
