Lighting accounts for over 10% of electric bills, but compact fluorescent lights use 50-75% less energy and last 10 times longer than incandescent bulbs. Washing full loads of clothes and dishes, keeping appliances clean, and air drying dishes can also save on energy bills. Heating water makes up 13% of energy costs, so using low-flow fixtures, fixing leaks, lowering the water heater temperature, and insulating the tank can reduce costs.
