Exactly. It's a quadruple whammy:

1. Most residences not being suitable for significant generation.

2. The return on investment is decades long (yes, so is double glazing, but that is useful for far more households), not that most households can afford it at all.

3. The total generation capacity is piddle, especially for government investment.

4. The materials that go into making PV panels are horrible to extract.

I'm not saying PV panels are useless, but they are not much of anything. Not something my lecturers at uni liked hearing/reading, but lo and behold pretty much nothing substantial has changed since. They're too busy blowing Sustainable Development smoke up their own arses though.
