1. Turn off lights – you would be surprised at how much energy is used by lights left on that are not being used, lights on in a room that no one is occupying. One or two lights left on can consume a considerable amount of energy, costing you money.
2. Turn down your water heater temperature – this makes a lot of sense if you have an electric hot water heater, but you can also save money by turning down the temperature of your oil, gas, or propane heater. Reducing the temperature of your tank from 140 degrees to 120 degrees can save a considerable amount of energy.
