Myth 1: It’s more efficient to leave a room at a constant temperature than turning the heat down overnight (or when you’re not home).
Fact: It takes less energy to warm up a cold room in the morning than it does to maintain a constant temperature throughout the night.
Myth 2: Turning the thermostat up higher than the desired temperature makes the room heat up faster.
Fact: It takes the same amount of time for the temperature to reach 20 degrees whether the thermostat is set at 20 or 30 degrees.
Myth 3: Changing my energy use will not result in worthwhile savings.
Fact: You can save hundreds of dollars each year by turning off lights, TVs and computers when they’re not in use, lowering thermostat settings when away and washing clothes in cold water.
Myth 4: Insulating my attic or basement will cause more heat to leak out of the windows.
Fact: Adding insulation to one part of a home saves energy and will not increase heat loss elsewhere.
Myth 5: Leaving a ceiling fan on will cool the room even when you’re not there.
Fact: Fans work by cooling the skin, not the air in a room. Fans move the air which helps to evaporate moisture on the surface of the skin, making you feel cooler.
Myth 6: It’s more efficient to leave lights on rather than turning them off because flicking the switch uses so much energy.
Fact: It’s always more efficient to turn the lights off when the room is not being used.
Myth 7: Compact Fluorescent Light bulbs (CFLs) cost more than regular light bulbs.
Fact: In the long run, CFLs not only cost less than regular bulbs, they will save you money. You would need to buy eight regular bulbs to last as long as one CFL and CFLs use only a quarter of the energy. You can save about $50 over the life of just one CFL. Since a typical home has about 30 light fixtures, imagine the potential savings.
Myth 8: It’s better to leave your computer running all the time because turning it on uses so much energy.
Fact. You always save energy when you turn your computer off when it’s not in use. Enable the sleep function to conserve energy during brief periods of inactivity.
Myth 9: Food will cook faster on the stove if you leave the setting on ‘high’.
Fact: Leaving the setting on ‘high’ does not cook food any faster. Once water is brought to a boil, save energy by turning the heat down and maintaining the boil with the pot covered.
Myth 10: When my TV, DVD player, stereo and computer are turned off, they are not using any electricity.
Fact: These electronic devices use standby power even when turned off. Over a year, this could cost you more than $100. Use a power bar to turn them off completely when they’re not in use.
