Nonsense. I can show you wind turbines that have been running, producing more energy each day that they run than it took to manufacture them, since the mid 60s.
The hills near our ranch are dotted with old, still working wind turbines, that require almost no maintainance (and that is a lucky thing, since people are not inclined to maintain things until they fail).
So if you took the energy output of that windmill it could produce all the energy it takes to smelt the ore, run the machines, etc. etc. without any other energy from any other source to reproduce itself?
That is a tall order.
I just wonder how long it would have to run just to heat a blast furnace one time.
Most of it is a product of cheap oil, or coal.
