A lot of good answers on this quora page: https://www.quora.com/Is-it-true-that-the-carbon-released-from-the-manufacturing-of-a-wind-turbine-is-far-greater-than-the-carbon-saved-by-substituting-wind-power-for-carbon-based-power https://www.quora.com/Is-it-true-that-the-carbon-released-fr... "US researchers have carried out an environmental lifecycle assessment of 2-megawatt wind turbines mooted for a large wind farm in the US Pacific Northwest. Writing in the International Journal of Sustainable Manufacturing, they conclude that in terms of cumulative energy payback, or the time to produce the amount of energy required of production and installation, a wind turbine with a working life of 20 years will offer a net benefit within five to eight months of being brought online." https://www.sciencedaily.com/releases/2014/06/140616093317.htm https://www.sciencedaily.com/releases/2014/06/140616093317.h...
