Newcomers to wind energy and even some old-timers who should know better often equate the size of a wind turbine to it's generator rating. A Vestas V80 for example is rated at 1.8 MW; a V82 is rated at 1.65 MW. While this is may be a useful shorthand among those unfamiliar with wind energy, the use of generator size leads to a host of problems when evaluating the technology.
