When an electric bill suddenly rises, many people assume their electric cooperative raised its rates. Sometimes that’s the case. But more often, the biggest reason is simple: You used more electricity.
According to the U.S. Energy Information Administration, nearly 90% of U.S. households use air conditioning. During hot weather, cooling systems run longer and more often. Even if the price of electricity stays the same, using more electricity means a higher bill.
Heat waves can have a bigger effect than you might realize. A few extra days of very hot weather may cause an air conditioner to run for hours longer each day. Refrigerators, freezers and dehumidifiers may also work harder during extreme heat.
If your bill seems unusually high, compare your electricity use with the same month last year. Most utility bills show the number of kilowatt-hours used. That number can tell you whether the increase came from higher use, higher rates or a combination of both.
You can also look for simple causes if you notice an unexpected jump in your energy use. A clogged air filter, a thermostat set a few degrees lower than usual or windows receiving direct afternoon sun can all increase cooling costs.
The next time your electric bill arrives, don’t just look at the amount due. Check how much electricity you used. The answer to a higher bill is often hiding in that number.
