The cheapest wind generator you can get in nz is $585.
It generates 200w at 40m/s wind speeds.
To get 1kw you need to have it running for 5 hours at top speed.

To buy 1kw hour off the power grid is only 17c.
I believe wind generator's have very poor rate of return for the investment.

40m/s = 144km/h

BTW Are we talking about the windmill or the cow?
Definately not viable. On windless days that is why you need to cow there.When the cow farts it can generate some power but the fart tax at then works out more than the money genreated by the windmill. And that aint no bull.
