Out the door? Turn down the heat!

One of the best ways to save energy as the weather cools down is to turn down the heat. Turn off your thermostat while you’re at work or out for long periods; that way, you only pay to heat or cool your house while you’re actually there to use it! Better yet, install a programmable thermostat, so you can set a heating schedule, or a smart thermostat, that can sense when you are not home.

Patch Up the Energy Leaks

It’s October – the start of fall and National Energy Awareness Month! Save energy by sealing your home with easy-to-use caulking or weatherstripping. The leaks and cracks in your home may seem insignificant, but added together they typically create a hole the size of a basketball!

Nature's Dryer

It costs about 50 cents each time you run your clothes dryer, which adds up quickly. You don’t need a clothesline or a backyard to air dry your clothes – use a clothes rack in your garage or your shower curtain rod to air dry your clothes at no cost.

Aerators and Your Faucet

Saving water is not only great for the drought – it also saves energy because less energy is needed to pump water to your home or to heat it up for household use. Conserve water and energy by installing faucet aerators in your sinks and save up to 700 gallons of water per sink annually.

Close That Fridge Door

Refrigerators use a considerable amount of energy – an average older model costs $118/year to operate. Control this expense by limiting the time you leave the fridge door open. The longer you let cool air escape, the more energy is needed to cool the inside back down!
