This. Man i'm considering in splurging on a bigger A/C to compensate for the added heat in my "computer room", it is currently running for 16h a day so i can survive this heat, that's 21KW/h a day and my humble 4 card rig is using 21.6KW/h a day, thats 42.6KW/h to generate 0.5BTC on average. Thank God in Venezuela we pay $0.011 per KW/h 
As someone who doesn't pay attention to detail (it's "kWh" not "KW/h"
), you are almost certainly in error.- Either the extra zero is a typo and you are in fact paying $0.11 per kWh
- Or $0.011/kWh is the generation cost and excludes the delivery cost, or vice versa (to know your effective rate, take your total amount billed and divide by our total kWh consumed)
Consider also that $0.011/kWh would be at or below the production cost of almost any hydroelectric dam in the world, including the Guri dam in Venezuela, which supplies 73% of the electricity in your country.
