So why exactly are wind turbines so expensive? I mean arent the generators alone $5-$10 million? One of my professors (hes just a physicist though) said he doesn't really understand why it costs so much either. The next week he brought up maybe there's sophisticated equipment making sure the gears and turbines are spinning at the correct frequency. Anyone know the absolute answer to this?
