The problem is that in the west green energy became a religion while in China it was just a practical solution when it made sense. They didn't have a problem to build a coal based facility or a sun based facility, depends on the needs and cost. Now that green energy makes more sense, naturally they ustilise more of it. In the west though it was all about doom's day predictions, culture wars and cancelations. So it all became a religion war rather than a mere technical consideration.

Why is that "the problem"? Religions are quite popular and successful in the West

The wealthy conservatives I know have (government-subsidized) solar installed on their second homes and cabins. They install it the second it makes financial sense.
