Tip Energy

[David Hogan]

Helping Out Your Air Conditioner - If you simply must turn on the air conditioner, make sure your unit’s filter is clean and get the refrigerant level checked – if it’s low, you may be wasting 20% of the system’s energy. Then, move the air as much as possible. You can do this with a ceiling fan (make sure it’s rotating counterclockwise), or by carrying a personal fan. By circulating air, fans make us feel cooler, yet they use only a fraction of the energy required by air conditioners.
  All electrical devices give off heat, so consider replacing old refrigerators and incandescent light bulbs with new energy efficient models. Unplug electronic equipment when it’s not in use.
   Close drapes and shutters on windows on the sunny side of the house. If it’s time to replace your windows, get the double-glazed type with a coating that reduces heat coming in from the sun.
   Plant a tree. In the summer, a deciduous tree in front of your window will provide cooling shade. In the winter, after its leaves have fallen, it will allow solar energy to warm your house.
