KamperKen: " If one drives past a wind farm one will notice that most are not spinning since most failed some time prior and were abandoned in place."

On a windy day in your typical windmill farm of, say, two dozen wind turbines, I typically see all but two or three turning, suggesting operating rates approaching 90%.

The windmill industry says you can expect annual maintenance costs on newer turbines around 2%, or $80,000 on a $4,000,000 windmill.
Over its 25 year life, that would mean repairs totaling $2,000,000.

How much to they earn?
I can't say, numbers not readily available, but conventional wisdom says that without government subsidies, windmills are losers economically.

To which the industry responds that government subsidies for wind turbines are no greater than those subsidies provided other energy sectors.

Take your pick.

Depends on what the meaning of the word "subsidy" is. Is is a tax break, or an outright grant?

Of course "the industry" is all RAT...so they're probably lying.
