Tips

Heating and Cooling

  • Turn down your thermometer if it is too hot and never open windows to cool things down. Open windows are the biggest wood frame energy-waster by far.
  • Try to keep your heat on between 65o and 75o during the winter.
  • Even if your house has air conditioning, use and electric fan instead whenever possible. It will use much less energy.

Lighting

  • Always turn-off the lights when you leave a room.
  • Try to stick with the lighting provided by Wesleyan, as it is the most efficient form.
  • If you do require additional lamps, use only compact fluorescent light bulbs (CFL), which use 75% less energy than conventional incandescent bulbs and last 10 times longer. You can get them free from the Usdan Computer Store.
  • Take down decorative lighting (string lights, ect).

In the Kitchen

  • Cover pots when cooking or boiling water.
  • Do not use an extra refrigerator. Fridges use an extraordinary amount of electricity, and mini-fridges are even less efficient.
  • Set fridge on lower settings: very cold settings use more energy and can spoil your food.

Water Usage

  • Fact: Hot water comes from your house's internal combustion system, so it takes a lot of energy to produce.
  • Turn the water on and off when you are washing your hands or doing dishes. Don't let it run when you are not using it.
  • Try taking shorter showers and/or turning the water off when you are washing.

Computers

  • Fact: One computer left on 24 hours a day dumps 1,500 pounds of CO2 into the atmosphere.
  • Shut-down your computer when you are not going to be using it for more than an hour. Contrary to popular belief, shutting-down does not harm your computer - it's actually good for it.
  • Do not use a screen-saver. Put your computer on stand-by.
  • Use power management features on your computer. Tell it to turn-off your screen after 5 minutes and go on stand-by after 15.
  • Laptops are much more efficient than desktops.

Appliances

  • Unplug anything with an adapter or charger, such as cell phone chargers, lap top cords, printers and speakers. Pretty much anything other than lights still draws power when off.
  • Plug in all of your appliances to a power strip or surge protector. Switch it off when you are not using the appliances.
  • Don't leave appliances on standby: turn then off.
