A vacant house in Michigan will set you back $75 due to the added fee's that the Michigan legislature allowed the Util's to hose us till the end of time.

But the season is nice our last bill was $125.00 I consider that a utility home run.

OTOH: My mother inlaw has a geothermal system a 3700 sq/f ranch sets her back $80 a month and she keeps it @ 70's during the winter and summer an equivalent house with a traditional system would be in the 500-800 mo range.
