Taken from link you posted: "Undoubtedly, a well-sited and well-built wind turbine would generate as much energy as it embodies in less than a year." Sounds like good payout time - wind turbines life span is typically 10+ years.

But the bottom line is this... For a long time to come—until all energies used to produce wind turbines and photovoltaic cells come from renewable energy sources—modern civilization will remain fundamentally dependent on fossil fuels. edit: I am not against wind or solar, but they in their current form need lot more oil and that will continue for a long time, probably our life times. edit2: The previous poster partially quoted a sentence, others would be well served if they read the full sentence.

  > edit2: The previous poster partially quoted a sentence, others would be well served if they read the full sentence. What? llukas quoted a full sentence. And I don't think you understand the term ‘green-washing’. It's when a company that has a bad environmental reputation does some sort of (tokenistic) project to appear ‘green’.

    It's not just companies but politicians also carry feel good campaigns, and so do governments.

  Educate yourself and stop spreading FUD. Solar panels already paid their cumulative greenhouse emission debt and if not it is likely happen very soon. Fossil fuels wouldn't disappear overnight but there is less and less real dependency on them and more of a choice of using them. There is no reason not to go wind/solar if looking just at greenhouse gases emissions. http://www.nature.com/articles/ncomms13728 http://www.nature.com/articles/ncomms13728 "As a result, we show a break-even between the cumulative disadvantages and benefits of photovoltaics, for both energy use and greenhouse gas emissions, occurs between 1997 and 2018, depending on photovoltaic performance and model uncertainties."

    Oh Please! You do not have to educate me, unlike Moral Horsemen, I already have 10 KW SolarPV, my disagreement was not with Solar that much. We are discussing Wind Turbines here. If a counter point article in IEEE spectrum is FUD, good luck! The major point you have not quoted it, Wind's intermittent generation relies heavily on an infrastructure that is majorly oil based. Also Wind kills lots and lots of birds.. but lets ignore that too.
