I find it a bit difficult to understand that something banal is socially positive. Then again, maybe I am just not too social.
The point is that science THOUGHT it is impossible
The point is that a scientist doing back-of-the-evelope calculations from wrong premises concluded that the bumblebee could not fly, and someone decided that he accounted for all "science"
As I have already written before, I don't consider this a matter of exclusion: you can have solar and wind power generators, and using building's surfaces to get more energy is a good option.
Photovoltaic energy on top of the buildings doesn't really scale with building size, so forget about it for anything but low-rise buildings. But low-rise buildings means more space dedicated to humans instead of wildlife. I think the ecologists may have something to say about that too
You can have wind _and_ solar power together, by the way: you can put solar stations on the south facing slopes and wind stations on the north facing ones. You can even mix and match them because solar onbly works during the day, but wind is there at night too.
