How many years of electricity produced by windmills is needed to cover the cost of mining iron ore and metallurgical coke, transport to steel mills, energy expended to produce steel within the mills, transport of huge heavy steel blades, etc.

Tally up energy used to create steel versus energy produced by windmills minus energy loss over transmission lines.
Bring it on. Debate it. Trump will kill it. Never play in the rust belt. Virtue-signaling elitists on the coasts versus flyover country.
You've got the correct response to the folly of wind and solar replacing oil and coal; they won't.
This goes beyond mining and creating steel. Electrical, from wind and solar, will not do the heavy lifting of refining ore, transport of heavy materials, and production of modern materials. And the big elephant in the room that the greenies won't discuss, are the more than 6500 modern materials made from oil that are necessary to make life possible today. Materials like asphalt for roads, roofing materials for millions of buildings and homes, solvents for machinery, paints for protecting all materials, chemicals for all sorts of things like medical goods and medicine, textiles, glues, fertilizers and the list is extensive.
Solar and wind cannot replace fossil fuels; fossil fuel use will never be eliminated, or we return to the dark ages without not just modern conveniences, but to an age of mass starvation, poverty and death.
