There's a story in today's paper about a northwest Omaha homeowner who wants to put up a wind turbine. Â The thing will cost $3,000 - $6,000 and generate maybe 800 kW-hours of power per year. Â Â Economically, this makes absolutely no sense. Â Â
As for the other story cited on this thread...
The Japp family expects to save $3,000 a year in electric costs after paying $33,995 to Prevailing Power of Shenendoah, Iowa, for a 46-foot wind turbine capable of generating 10 kilowatts per hour at maximum wind speed. "After the initial cost, here is really no more expenses for 25 years," Japp said.
No expenses for 25 years? Â This machine is maintenance-free for a quarter-century?
Save $3,000 per year in electric costs? Â Cripes, how much power does the Japp family use, anyway? Â At 8c per kWH, $3,000 translates to about Â 37,500 kWH. Â Â That's more power than my house consumes in three
years. Â Â
"....capable of generating 10 kilowatts per hour at maximum wind speed."
Take out the "per hour" and this might be a technically correct statement. Â
Too bad the wind rarely blows at design speed.
