7 Myths About Energy Savings You Should Know
It’s never a bad idea to listen to good advice, but sometimes the information that gets passed around as fact about energy savings is actually a myth. Here are seven major myths about energy savings you should know.
1. Myth: Energy efficiency and energy conservation are the same thing. Truth: Energy efficiency means getting the most benefit out of the energy you use. Energy conservation means reducing the total overall amount of energy consumed.
2. Myth: Using energy-efficient HVAC equipment will automatically reduce monthly bills. Truth: Even the highest-efficiency HVAC equipment will not produce savings if not correctly installed and properly sized. Your home must be well insulated and air leaks in the ductwork or elsewhere must be located and sealed.
3. Myth: Use duct tape to seal ducts. Truth: Surprisingly, common duct tape is not recommended for sealing ducts. The adhesive can dry out, letting the tape fall away and reopen leaks. Instead, use mastic or metal tape for duct sealing.
4. Myth: Turning a device off stops it from using energy. Truth: Many appliances and devices still use a small amount of standby energy when plugged in, even if the item has been turned off. Unplug the device to eliminate all energy use.
5. Myth: It’s cheaper to leave lights and appliances on rather than turn them off and on as needed. Truth: The constant consumption of energy from a light or device that is left on will always be greater than the small surge of power used when turning them on.
6. Myth: Sealing electrical outlets stops a major source of energy loss. Truth: Generally, the air and energy loss at electrical outlets is very small. However, as part of a comprehensive home-sealing effort, you should also seal outlets to prevent leaks.
7. Myth: Insulating the ceiling will just cause more energy to leak out elsewhere. Truth: Ceiling insulation will not force more energy out of your windows or existing cracks and gaps. Insulating your ceiling will, however, prevent temperatures in the attic from affecting temperatures in all the rooms under the ceiling.
