The one, teensy, weensy problem with the wind industry's «save the planet» pitch is that 100 % of the capacity from intermittent and unreliable wind power has to be backed - up 100 % of the time by fossil fuel generators running in the background and burning fuel ALL the time — and, therefore, increases CO2 emissions in the electricity sector.

Each as tall as the Statue of Liberty, the turbines use 240 - foot - long blades made by the Danish company LM Wind Power attached to a 6 - megawatt Haliade generator made by GE Renewable Energy in France.

**** Remember all that huff and puff put out over the last few months by the Clean Energy Council and near - bankrupt wind power outfit, Infigen about wind power becoming so cheap as to be competitive with coal and gas fired generators?

According to the IESO's daily generator report, the wind turbines could have supplied almost 84,000 MWh * of power, or about 27 % of all the power consumed by Ontario's ratepayers (approximately 83 % of their capacity).

The wind turbines utilise generators from US provider GE (General Electric) and according to some estimates given by GE and Max Bögl Wind, the wind power plant could generate 10GWh of energy annuawind turbines utilise generators from US provider GE (General Electric) and according to some estimates given by GE and Max Bögl Wind, the wind power plant could generate 10GWh of energy annuaWind, the wind power plant could generate 10GWh of energy annuawind power plant could generate 10GWh of energy annually.

Under the LRET, a REC is issued for each MWh of wind power dispatched to the grid, on the assumption that it in fact reduces or abates 1 tonne of CO2, that would otherwise be emitted by a conventional generator.

The 99.33 % of wind power output that went AWOL for hours (at various times, 3 days straight) was, instead, all supplied by conventional generators; the vast bulk of which came from coal and gas plants, with the balance coming from hydro.

E.ON operates numerous transmission grids in Germany and, therefore, has the unenviable task of being forced to integrate the wildly fluctuating and unpredictable output from wind power generators, while trying to keep the German grid from collapsing (E.ON sets out a number of the headaches caused by intermittent wind power in the Summary of this paper at page 4).
