There is a lot of great advice on how to be more energy efficient - using ENERGY STAR-rated devices, for example. But then there's the not­ so-great advice: the misinformation, mistakes, and myths that could lead you astray in your efforts to save on your electric bill. But fear not! Here are a few common myths we encounter - and the truth to bust them.

MYTH: Switching appliances, computers, and electronics off when not using them will wear them out faster.
TRUTH: Modern electronics and appliances are built to perform just as well with frequent shutoffs. Most computers are made with this in mind and use the on-off cycle to install updates and perform other necessary self-maintenance. So go ahead and shut off and save power.

MYTH: Adding insulation in the attic will cause more heat to leak out the windows.
TRUTH: Any added insulation will help your home maintain a stable temperature. Adding insulation to your attic (and, more importantly, sealing your ceiling) is a great way to help make your home more energy-efficient.

MYTH: If you close vents in your unused rooms, your HVAC system uses less energy.
TRUTH: This one seems counterintuitive, but unless those unused rooms are somehow sealed up airtight, the air is still going to circulate. Closing vents can make your HVAC system work harder than usual by causing a backup in internal pressure. You would be better served by adjusting your thermostat or switching to a more efficient system. Sealing your ductwork, air sealing your ceiling and band joists, and adding insulation will also ensure that your home minimizes energy use and keeps you comfortable.

MYTH:: New homes are required to be more energy efficient.
TRUTH: Not necessarily. A home's age doesn't always tell you whether or not it's energy efficient. A home's construction is a larger indicator of its energy efficiency. That's why we recommend looking for homes built to the specifications of the Power Moves Home Program, which is designed specifically with energy efficiency in mind.
