+ - Wind turbine energy payback time less than a year-> 2

Submitted by mdsolar
mdsolar (1045926) writes ""Researchers have carried out an environmental lifecycle assessment of 2-megawatt wind turbines mooted for a large wind farm in the U.S. Pacific Northwest. 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.""

Wind turbine energy payback time less than a year

  • And I thought the article was all hot air.

    Up to some limit this is good news.

    The reality is that excellent locations for wind farms are not all that
    common. I can see a wind farm bubble forming as lower and lower quality
    sites are developed.

    So for now make hay while the warm dry winds blow.

  • The quick payback is just for the energy components; it doesn't discuss total costs for materials, labor, installation, etc.
