We have a 1600 sq ft pool home, so the pump sucks a lot of electricity, and my IT-job husband works from home using a PC and 2 monitors 9 hours a day. However, we have turned the thermostat up to 80 during the day, and 76 at night. All the light bulbs are LED, and we regularly change air filters and maintain the AC unit. Nobody in this house needs more than a lukewarm shower when it's still this hot outside, so the hot water tank is turned down. We unplug appliances when not using them, turn lights off, etc. We try our best to be energy-efficient. We're forced to use Duke Energy, and I hate them with a passion, so I work hard to not give them even a single dime more than I have to.
However, we still use ~35-40 KWH a day at this time of year (i.e., highs still in the upper 80s and low 90s), and even more in the summer months. AC to combat that kind of heat and the sunshine beating down on the roof all day long sucks a lot more power than you might think.
You don't say how big your house is, or what temperature you keep it at. However, sometimes there are hidden things sucking power around your house. Maybe your fridge is old or needs its coils cleaned? Have you changed your AC/furnace filter lately? We dropped literally 20 KWH a day when we first moved in here and finally got around to looking at the filter - the last tenants probably never changed it once and it was filthy. Also, sometimes AC units get clogged with sand or debris. They need to be cleaned regularly on the inside and outside or they suck too much power - you can find videos online on how to do it without damaging anything.
Good luck and stay cool while the hot weather lasts!
