In the end, how much reliable fossil fuel energy is expended in exchange for unreliable, politically correct wind energy?

It looks like wind power involves a lot of travel, massive trucks, cranes, earth movers, steel and cement work, welding, new transmission line installation, etc etc:

I was surprised to learn that transportation expenses are a big part of the cost of installing a wind farm. Two weeks ago, however, I was on the highway just east of Portland, Ore., and I saw just how big a truck needs to be to carry one wind turbine propeller blade to a wind farm site.

It takes a lot of runs to get these huge pieces of metal to their destination. That's why there is a growing demand for large-load transportation specialists who can cart towers and propellers around the countryside without taking out a Prius two lanes over.
