I'm in California, I own my home so I pay my own electricity. I'm in an electricity worst-case scenario. 
No you're not... If i calculated right that is 15 cent /kwh. Thats really high for american standards, but cheap compared to germany. We currently pay 22 (euro)cent per kwh ~ 25 $cent. I'm running two rigs with 1300W. Thats almost 7 a day just for power.
