Ah Ringer, perhaps you do not comprehend as well as you think you do

Look again very carefully at your 4.3GW that only covers the turbine's manufacture, the turbine's operation, the turbine's transport, the turbine's dismantling/disposal and turbine's transmission. And please note we are only taking their word for it those items do not appear in any breakdown.

Nothing whatsoever about the tower the turbine stands on, nor the construction of the roads, nor the building of the foundations.

Any idea the electrical power required in producing one tonne of steel, or one tonne of cement? How about the electrical power required to grind one tonne of rock to one tonne of hardcore?

My figures come from a study by the University of North Wales on the efficiency of windfarms
