Since the Solar Panel has an advanced tier, the wind generator also should. Going from that premisse, it would be really cool if the Advanced tier of the wind generator had a larger size, like 16 blocks wide (or maybe more but I'm not keen that it's possible). Then the "visual polution" could be their problem (just like irl) and the blades could damage entitys based on the speed they are turning at (maybe making a hitbox encasing the blades unecessary?).
Just in case this suggestion is accepted, I made some research and a 32 meter (2chunk) wide rotor would generate just over 300kW (though I don't know how that translates to forge energy) and the relation is square, where a half-sized rotor (16m) would generate 1/4 of that (75kW) and one with twice that (64m) would generate 1.2MW. [The blade diameter]:[Base to generator housing] is about 1:1
