> I'm unsure what planet you're from with that comment. Let's put it this way: there's that much variance in population density on this planet. Around myself, personally owned roof is a luxury. A parking lot is a 5-story building if not 5-stories structure directly below a building. On the other hand, to some others, solar panels as sheds in a ranch is just a fancy shed that they're going to need anyway. Rooftop solar for one household on a midrange under-$1m 50-story mega-condo with 20 rooms per floor reduces power draw of the building by 1/1000th. Outside the mega-city is mountain ranges and water sources. The rest 999/1000th of power has to come from there if it can't be sourced in-city, which means stripping mountains to bare soil and covering lakes in mega floats and dealing with environmental releases all the time, or alternatively just finding a valley in the mountains and building massive metal cans to boil rocks could work too. Might sound like a William Gibson parody, some places are just like that. Some parts of his works are effectively just portrayals.
