Wind turbine payback

Researchers have carried out an environmental lifecycle assessment of 2-megawatt wind turbines mooted for a large wind farm in the US 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.

That, reports a research group, is the measure of how dense they will get under normal conditions, and it?s a value that seems to be constant for similar aggregates across an impressively wide size range from nanometers to tens of meters.
