<prompt> Human: I rent a one bedroom apartment with 4 units in the building. On my February bill for 2018 the electric company says I was using 28.6 kWh per day versus 5.3 kWh per day last year. Nothing has changed in our household as far as major appliances or using electricity. Heat is gas and paid for by the owner. We have a gas stove. I dont mine digital currency.Only three noticeable changes have occurred in the past few months.:1 our coffee maker would recently trip the breakers on some morning since Jan 2018 and this has never happened since 2016.2 We noticed many nights that water wasnt the usual hot, but became luke-warm when showering or doing dishes. The building has one water heater.3 New roommates above us.Ive reached out to the electric company for followup this week but want your opinion is well. Im going to see what they say before reaching out to the landlord. Im wondering if were footing the bill for the entire building or if the water heater is hooked up to our meter or if the previous average we paid was inaccurate and they fixed that.  <response>: I dont have an answer, but am upvoting because you have correctly expressed the problem in kWh and not in dollars.
