Turbine Power

(from Treehugger.com)


So, how long would a wind turbine have to run before it made up for the energy used in its manufacturing?

6.8 months.

"The life cycle assessment of a 3.0 MW wind turbine indicates that it would have to generate electricity for only 6.8 months , of their assumed 20 year useful life, before it produces as much energy as is used during the manufacturing phase. “This, they say, means the turbine model earns its own worth more than 35 times during its energy production lifetime.”

More wind turbines, less coal and nuclear.

Yay! The present is a very exciting time.
