slowing down the wind? not quite what happens, affects
local weather a bit, not global climate, unless we cover most of the planet with turbines and don't investigate efficiency enough
slowing the tides? does the mega-tons of shipping on the worlds oceans stop the waves?
does damming innumerable rivers to generate electricity change the global dynamics of the hydrological cycle, causing drought? do all those dams reduce sea level or increase salinity of the oceans?
does "harvesting" sunlight with PV panels make days darker? does generating hot water to run steam turbines with solar concentrators make the planet cooler or hotter?
lots of discussion possible, but likely belongs in the Spoon
