I think that’s it, especially if it’s in like that all day. If she’s in an apartment anything like mine the heat from the neighbors on all sides seeps in. 2 bed mill style with poor insulation but keeps my apartment at 65 without having to turn my heat on. If my heats on at 68 for a full month my bill would be around 4-500.

Check to make sure she didn’t accidentally sign up for renewable sourced energy, they quote me 2x+ for the same service as well
