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 S19-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 S19 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)?
