Over a typical 20-25 year lifespan, a modern wind turbine generates 20 to 25 times more energy than was invested in its creation. This Energy Return on Investment (EROI) is competitive with or better than many conventional generation sources once fuel extraction costs are.

By means of a mechanism, normally a hydraulic lift, the blade is raised, reaching an inclination of around 65 degrees, or even rotated, to avoid the sail effect of the wind, thus making it easier to drive on narrow roads, with sharp bends or even through urban centres.
