You definitely need to modify your poll.
The AVERAGE price of electric in the USA is around 12 cents/kwh, and there are 2 counties in Washington State that are around 3 cents/KWH
Anything over about 15 is pretty close to being unprofitable to mine with even the current most efficient units (SP20E, SF3001, S7).
$0.2/KWH is quite HIGH by US standards, fairly high by the standards of a lot or most of the rest of the world, and forget trying to mine at a profit at that kind of electric pricing.
https://en.wikipedia.org/wiki/Electricity_pricing is a good place to start your research. It's not definitive, but it points you in the right directions.
Also, most "renewable energy" ends up costing MORE than commonly used sources, at this time, though with government subsidies it might come in as competative, and if you're WAY out in the boondocks you might not have any other viable choices. Some of those options were getting to be competative when oil was over $100/barrel and coal/natural gas were following suit somewhat, but at current fossil fuel pricing the competativeness has dropped. I'm certain that non-fossil options WILL have to get more common eventually though, as even Coal is a finite resource much less oil/natural gas, and stuff like Ethanol isn't much better than break-even at BEST vs the energy used to MAKE that stuff.
Long term, Ethanol and the like might be a good option - if wind or solar power is used to make it. Biggest issue is that current EFFICIENT Ethanol making requires fairly constant power input, which neither wind nor solar can manage (though Hydro and tide power genration can).
