God, if I was not so lazy I would be setting up some west Texas wind/solar. I wonder how much those turbines cost to deploy.
I looked at the numbers.
1 turbine of 2-3 mW is $2-4 mil.
Lets assume $3 mil.
It looks like it can probably 'feed' 1000 S11-say, another $3 mil.
maintenance-they say about 50K/year.
2 people (at the minimum) taking care of 1000 miners-another $100-150K/year.
Total investment for the first year $6.2 mil.
1000 S11 would make roughly 20BTC/mo or $0.47mil/mo (current prices) or 5.64mil/year if everything stays put (it doesn't).
So, about 13-14 mo to profitability if turbine is fully paid for, not a loan.
However, second year is almost pure profit

.
This business would need to very strategically buy new miners (on the cheap when possible).
I am not sure how reliable the wind is (it probably isn't)?
Why does the business have to get more miners? If it's pure profit on the second year, the smart thing to do is milk that profit until it's gone, all the while buying more corn.
