Assuming that this is not an overestimate (which is probably a bad assumption), this much electricity is worth about $250 per year at the residential consumer average price of $0.10 per KWh. At the wholesale price of electricity it would only be worth about half as much,$125 per year.
Assuming the 20 year life advertised on the Air Source Technologies website is not an overestimate (again, probably a bad assumption), there is an outside chance that this wind turbine might produce $5,000 worth of electricity in the next two decades.
How much does the wind turbine cost? That number was somehow missing for the in-depth investigative reporting presented in this article.
Please do not respond by telling me that much of the installation cost can be off-set by state and federal grants and renewable energy credits. This just means the money is coming out of my pocket, not yours.
