Solar I think is the least intrusive to the enviroment. Just think of a salt flat or desert bed lined with solar panels. That could be a good start. Fusion as I understand it has a radioactive by product. Not sure what Biomass is, Hydroelectrice usally involves much change to a landscape to build the damn, then there is the matter of flooding the area, then killing all the fish and the creature that get huge at the mouth of the damn eating in the deep water. This is a man made change I think will effect us over time.

Nuclear... Nah I know it is clean but the radioactive by product is scary. How can you store something for hundreds of thousands of years safely? Wind kills many many mnay birds belive it or not.

See the float on wind curent and.... BAM dead fucking bird falls to the ground after striking the wind mill.
