Where a 4-bedroom house's electricity goes
Heating and cooling lead
For most homes, AC and heating are the largest single loads. In a small apartment, window units or a heat pump dominate the seasonal swing — summer bills can run double the spring baseline.
Water heating is the quiet second
An electric tank water heater typically adds $30–$50 a month for a household of three or more. Lowering the tank to 120°F and insulating hot-water pipes trims it.
The always-on baseline
Fridge, router, standby power, and lighting run around the clock — usually 150–250 kWh of a 4-bedroom house's 1150 kWh. That's why bills don't fall to zero even when you're away.
