Our place was unoccupied for like a year and so now PSE&G's estimates are all based on the idea that we use essentially zero electricity and gas per month. I've tried to post my own readings on their website (there is a place where you can do that) but they ignore them. My little "energy used" graph on their website is totally flat except for the one month they came and checked it, which is through the roof because it is multiple months rolled into one. So irritating!
