I guess I get my figures from my electric bill. I have a 2500 sq foot house and my average monthly bill is $115 - $130. My last house was about 1,300 square feet with an average bill of $90 a month. Before I got the reef tank my average bill was $70 - $75 a month. Both houses are electric only, no gas.
On my reef tank my mh's were on 8 hours a day, my t5's were on 10 hours a day. The flourescents for my refugium were on 12 hours a day.
*edit - guess I was wrong, looks like reef tank cost me around $15 a month, not $10.
