A wind turbine with a working life of 20 years will offer a net benefit within five to eight months of being brought online.
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.
Wind turbines are frequently touted as the answer to sustainable electricity production especially if coupled to high-capacity storage for times when the wind speed is either side of their working range. They offer a power source that has essentially zero carbon emissions.
Coupled lifecycle cost and environmental assessment in terms of energy use and emissions of manufacturing, installation, maintenance and turbine end-of-life processing seems to be limited in the discussions for and against these devices. “All forms of energy generation require the conversion of natural resource inputs, which are attendant with environmental impacts and costs that must be quantified to make appropriate energy system development decisions,” explain Karl Haapala and Preedanood Prempreeda of Oregon State University, in Corvallis.
