California has noticed that solar power panels are a great deal cheaper than they used to be. Therefore, they are going to force, by law, all new houses to be built with solar power-generating technology. There is a certain amount wrong with this decision – why, to be fair about it, the heck are they doing this?

This is the inverse of something I pointed out here recently. The very fact that a government would go to the trouble of banning something, say McDonald’s, is evidence that you know people would like to have it. Otherwise, you’d not need a ban, as no one would want it anyway. The inverse of that applies to California: Why would you force everyone to do what you’ve just noted is cheap enough that it’s in their own interest to do so naturally?
