Manatees like when you leave a freshwater hose leaking into the saltwater. Ecologist tell you it is bad though because the animal develops a dependency towards human intervention that might not be a long term phenomenon.

Where I live the industrial areas are pretty much two elevations across the entire lot. You get the warehouse where it is a massive building with a flat roof of a single height. And you get where the trucks pull in and back into the warehouse, also a bunch of flat cement with fixed height requirements one could trivially deck with solar.

And when I looked at industrial areas in denmark, or at least in the vicinity of copenhagen, I saw pretty much exclusively that outside actual oil refineries. Just a ton of warehouses, flat roofs, truck yards. Again already with some solar, just only implemented to the extent to supplement a buildings utility bills, using only a small fraction of that massive flat roof, not to produce an excess of energy. I dare say most industrial property the world over looks more or less like that: rectangular building, flat roof, truck yard.
