How can I reduce property utility bill?

[Joe Boggin]

I made an offer on a property that is considered a boarding house. It is a small row home in Philadelphia that is broken up into three rooms. The only common areas are the bathroom and the kitchen and the backyard. The property is all electric. The electric is going to be in my name.  Hypothetically I would be collecting $1200 a month or $100 per week per room. Electric can range anywhere from 300 to 500 for homes of the size. There is no dishwasher. There is no washer and dryer. 

 Are there any absolute pitfalls to avoid when it comes to electriic?  Considering the entire house is electric any reduction of electric usage will increase my bottom line. Space heaters vs baseboard heat?   Should I avoid window air conditioners at all cost and opt for the new energy-efficient floor air-conditioners?   Instead of having one large refrigerator in the kitchen should I get three mini fridges for each room?!
