A windmill, and windfarm, takes energy out of the wind and converts it to electricity. Over time, and after lots of years of windfarms, we could have taken enough energy out the wind that winds would slow down around the planet. What do you think will happen?

(NOTE: back in the 1800's they thought there was infinite coal and oil and never imagined environmental issues with burning it, so this question may be a real problem).

I want to build my own windmill for electricity

is there a
1) cost effective
2)electrical generating
3)efficient
windmill that could be installed on a residence.

i've seen units that cost about 40,000.00 USD.
(i donnot think this is very cost effective.)

My family is thinking of using a solar panel and a windmill to power our home. Do you think this would work well in Northern Ohio?

Ok, so im in a go green camo and we just got mini solar panels to take home (about the size of an itouch) i know i cant make those at home but i was wondering if i could make a windmill at home. Not a big one, just a small one (i wouldnt use it to power anything just for fun to try this out.) but how do i make one and hwo do i hook up the wires?
