<prompt> Human: I live with one other person in a three bedroom apartment at college. We each pay 720 a month I know its high, and we do not owe any additional amount for the unoccupied room. We have been living here since the start of school, late August.The only additional pay we owe is for electric each month split between the two of us. The electric charge for each month is the following:September: 94.63October: 97.39November: 107.04December with nearly a month Christmas break, into part of January, where neither of us were in the apartment: 94.44January: 129.82February the issue: 180.84We do not have any proof that the electric charge for February is wrong, but we have not had any significant electrical behavior changes that would cause the price to increase this drastically. I want to go talk to the people about it, but I dont really have a solid argument. What can I do or say to them? Or what should I look at, maybe I am missing something?Edit: To address some of these helpful comments:The heat is electric and we are in Erie, which many of you probably know is cold af. We usually keep the heat at 63. Even if February was colder on average than December, could that alone cause the cost to increase that drastically?No new appliances, no space heaters. We havent yet looked at the meter or tested to see if anyone is stealing from us or if there is any community cost, but we plan to. As far as we know, the cost kWh has not increased. Also thanks to everyone who has responded thus far we appreciate the help.  <response>: Record low temps in DecJan for much of the country has equaled record high bills in Feb.
