I hate to repeat myself, but is seems in place.
I once reported about how much it costs to build a single wind generator.
The amount of electricity to produce the steel for the generator, the copper for the wires, the fiberglass for the blades, the steel in the blades, the steel in the foundation, the amount of concrete needed for the foundation, the amount of diesel to transport all these thousands of tons of steel, concrete, fiberglass, copper, parts, the cost of the crane to build the windmill, the costs of the building in manpower hours, the costs of repairs, service, spareparts and all the insurances if something goes wrong....................
This single windmill will NEVER PRODUCE THE ENERGY THAT WAS DESTROYED just to build the damn thing....
