Eleven Energy Myths

I have no commercial utilites and must generate electricity so saving energy is important to me. The less I need, the less I must invest in my system. However, it's not just a pragmatic interest. I have an innner passion for preserving our environment. For me, preserving the environment is a spiritual act. Perhaps you will find this list of myths interesting and helpful.

  • Myth: When my appliance is turned off, it's off.
  • Myth: Fluorescent lighting is unhealthy.
  • Myth: Halogen lighting is super-efficient.
  • Myth: Cleaning refrigerator coils improves efficiency.
  • Myth: Leaving lights, computers, and other appliances on uses less energy than turning them off and also makes them last longer.
  • Myth: Energy efficiency products increase the initial cost of houses.
  • Myth: Insulating the ceiling will just cause more heat to leak out of the windows.
  • Myth: Switching to electric room heaters will reduce your energy bill.
  • Myth: Electric heating is more efficient than fuel-based heating.
  • Myth: Buying an efficient air conditioner or furnace will automatically reduce my utility bill.
  • Myth: Installing foam gaskets in electrical outlets will significantly reduce air leakage.

Additional information: The energy crisis has given rise to a growing set of energy myths. In this article, researcher Evan Mills of Lawrence Berkeley National Laboratory's Environmental Energy Technologies Division reviews the myths and then lays out the facts. (

I question the reference to the refrigerator coil myth. By cleaning the coils the system works more effectivly and would therefore be more efficient. It takes less energy to transfer the heat when it is clean.

Thom, Here's the "Myth" and related "Fact" from the full article.

Myth: Cleaning refrigerator coils improves efficiency.

Fact: While this seems intuitively logical, and very small savings may indeed arise, efforts to actually measure this effect on residential refrigerators have typically come up empty-handed.

Sometimes we put plastic over the windows in winter here, as we have no storm windows. And the thermostat is set at 65 - we just wear layers and sweaters. I've found that cool air in a home is healthier. And, if we eat frequent small meals we stay warm.
