u can power the whole thing with a windmill
they have units up to 10kw a hour a 5kw a hour would do it for most ..........................just rem when u are doing this the state is allowed on your land any time to inspect the gear to make sure it is up to code
in my area a 2kw mill will pay for itself in 3.2 years after rebates and all that the cost out of pocket is about 5000..............but to do this u have to feed into the national grid
use this and u will get the numbers u need to make your choice
