An industry that showed so much promise—particularly against the background of international efforts to curb the effects of climate change—is now in the doldrums.

The solar power industry has never shown promise except as a niche product. That's because it is not viable as a mainstream provider of electricity. If it were a promising industry it would not require government subsidies.

My kid took down a six decade old Aermotor mill on one of the wells at the ranch he foremans and put a two panel solar pump in it’s place. I was surprised at how good it works. Produces from a couple of hundred feet.
Solar has some uses.
