Absolute bollocks
A decent project will payback in 7 years!!!
It's Solar PV which can take longer to payback than the panels last!! But costs are reducing.
7 years financial payback maybe slightly optimistic, unless very efficiently contracted and managed. But most certianly NOT 300 yrs.
However, i don't believe that there is enough evidence around proving the environmental benefit of wind turbines, ie. the CARBON impact, and the period it takes to be saving carbon in comparision other sources such as Nuclear. There is significant infrastructure build as well as the tubines themselves to be considered that all impacts (construction, materials, waste, transport, etc etc). Consider the number of turbines required to supply the same as a reasonable size power station.
Very interesting topic though, that impacts on everyone environmetally and financially.
