Per our previous discussion about wind power, Home Power magazine's
current issue contains a formula for estimating output from a wind
machine based on average annual wind speed. To wit
kWh per year = [rotor area (sq. ft)] x [annual average wind
speed (mph)]^3 x 0.085 x
a pottery list or forum could tell you that.

Hello folks,
I took an alternative route for consuming wind power electricity
this month since it was just offered in my community.
My power company, Xcel Energy, added me to there wind resource
list to become a 100% consumer of wind turbine electricity for
about $4 dollars U.S. more per month.
colleceted in new england and nyc just wanted to share that
with you all cheers kelly

Hi Kelly,
I'm not a advocate of major corporations generally if at all.
I'm happy my one and only source of electricity offers a
renewable alternative to fossil and nuclear energy. My state
of Wisconsin USA has hydro, wind and biomass in the mix but
I'd like more of it in the mix. I've waited
having a wind generator of any size is gonna add a lot of vibration to your
home and if thats not enough to drive you nuts with extra repairs and loss of
sleep there is also the problem of mechanical resonance ... imagine living in a
home with a giant tuning fork sticking out of it .
Presumably it doesn't necessarily have to be mounted on the structure of the
house?

On wind turbine ratings the average power out of a wind turbine will
generally be much less than the rated power. Unless, of course, you have a
nice constant 28mph wind with no turbulence or variation most turbines
tend to be rated around 25 to 30mph. I have had a little 200 watt rated
