How can you split a utility bill that has 3 rooms with 1 room having?
How about this. Propose the following to your housemates . . . Do some research to determine which of these three patterns uses the most energy. Lets say that the heater uses the most energy, the refrigerator is in the middle, and the television uses the least. Now measure the square footage of the three rooms. Look at which has the best window arrangements. Which has the most closet space. Each resident should think about which room they like best. Finallylet the person who uses the least energy have first pick among the three rooms in the residence. The second heaviest energy-user gets second pick. The heaviest energy user goes last. After you have done any necessary room switching, split the bill equally. When you propose this arrangement, there is every likelihood that people will suddenly think of ways to save energy. The heater person will get an electric blanket and some sweaters. The refrigerator person will decide that the common area refrigerator is fine. The television watcher will get a smaller televisionor even get rid of the television and read more books. So you reduce the overall energy consumption and save money for all three of you, and each of you can keep the room they have. And save the Earth too.
