The "expected savings" are claimed to be $150,000 - $200,000 annually.
assuming the project comes in on budget (when has that happened?)
that the projected savings are as expected (when has that happened?)
it will take 21 - 28 YEARS for the project to pay for itself and start actually saving money.
The question of course immediately comes to mind: what is the life-span of a wind turbine?
Doesn't this just have boondoggle written all over it?
