I agree but just want to add that at least some people in apartments and condos can still produce and use solar-generated electricity. Here's a cool example:

Although I have rooftop solar producing around 200% of our usage annually, I was inspired by this story and have been increasingly using our offgrid LFP (LiFePO4 / lithium iron phosphate) backup batteries with solar panels to power certain things.

I think people in apartments would need rooftop access (ideally), equator-facing windows or a balcony, at the very least, for this to make ecological sense as there's a carbon cost to manufacturing batteries and solar panels. But it's doable and some people are doing it!

Here's another:
