Add energy-efficient showerheads and faucet aerators These can reduce the amount of water released from a tap by up to 50%, which means less hot water to be heated.
Heat water to the right temperature The recommended temperature is 120°F (49°C).
Repair leaks at once A dripping faucet can waste 6 to 10 gallons (23 to 38 liters) of water a day. Replace worn-out washers.
Insulate hot and cold water pipes If pipes are exposed beneath your home insulate them with special pipe-insulating foam, or tape a standard insulation blanket around them. Keep cold pipes from freezing and hot pipes hot.
Turn your water heater off when you're on vacation If you plan to be away for more than five days turn your water heater off. Post a reminder to turn it on when returning.
Use drapes to insulate Keep drapes closed to keep warm air in. Open drapes to allow the sun's rays to help warm rooms.
Take a shower instead of a bath The average bath uses twice as much hot water as a 5-minute shower.
Turn faucets off when not using hot water Running water non-stop during shaving or brushing teeth is wasteful. Turn on the faucet when necessary and save thousands of gallons of water a year plus the energy needed to heat it.
Apply weather stripping to stop drafts around doors and windows Install draft guards (available at most hardware stores) beneath doors. Add weather stripping to windows and door frames.
Caulk smaller gaps Many homes have cracks and leaks that are equal to a 2 feet by 2 feet open window.
Double insulate windows Storm windows are an effective energy saver for leaky windows. An economical alternative is plastic sheeting.
