From what I can find, the best rate you'll pay in Sweden for electricity is about 8 eurocents per kWh, which isn't very good. That's what large mines and data centres pay.
KnCMiner, based in Stockholm, operates about 7,000 machines. While the mining companys electric bill in March came to $450,000, the computers mined 21,000 bitcoins, according to co-founder Sam Cole.

$12,600,000 - $450,000 = $12,150,000
Do not, ever, in any way, feel sorry for these c@ck-suckers.
