I love wind... high ERoEI, plentiful, clean.... and if we have a large enough national or continental wide grid, it might even supply higher than previously expected capacity loads... at least in Europe.
"The output of some renewable technologies, such as wind, wave, solar and even some CHP, is naturally subject to fluctuation and, for some renewable technologies, unpredictability relative to the more traditional generation technologies. Based on recent analyses of the incidence and variation of wind speed, the expected intermittency of the national wind portfolio would not appear to pose a technical ceiling on the amount of wind generation that may be accommodated and adequately managed."
