It typically takes about six months for turbines to achieve energy-payback time, or EPBT, the time it takes for a system to generate more energy than it took to make it.
The US Environmental Protection Agency report said the typical lifespan was 20 years for wind turbines. Other sources estimate from 18-25 years.
I estimate this gives a return of 40-1 but some more conservative estimates are a 20-1 return (they are probably adding other costs not just energy in and energy out).
It's no wonder that the energy sector is pouring money into wind turbines.
Would you take those odds of 40-1 on a sure thing?
