Green Guide: Energy Conservation

Why? In the United States, approximately 4 metric tons of CO2 equivalent (almost 9,000 pounds) per person per year (about 17% of total greenhouse gas) emissions from homes are electricity use and heating.

TIPS to save energy


  • Use natural light rather than electric when possible
  • Replace your incandescent bulbs with compact fluorescents, which use 66% less energy and last 10 times longer. And recycle properly when done!


  • Keep windows closed when the heat is on. (If it is still uncomfortable call 8-8000 for Facilities Custer Service.)
  • Adjust the heat, in winter, if you have a thermostat. The NJ Clean Energy Program suggests 68F during the day and 60F at night or when not in your room.

When you leave the room:

* Turn down the thermostat, close the windows, and turn off the lights.

* Take the stairs instead of the elevator! Save energy and get exercise!

* Turn off and defrost the refrigerator over logn breaks

Computers, Cell Phones and Other Electronics

  • Enable the sleep mode (instead of screen savers) on your computers.
  • Unplug electronics when not in use because they still drain energy. Consider plugging all electronics into power strips so you can conveniently flip one switch to turn everything off at night.
  • Buy Energy Star appliances and electronics. See


  • Wash clothes on the cold water cycle (it saves energy used for water heating) and only run full loads.
  • Air dry your clothes when possible.

Join Your Peers

  • Pledge to Pull the Plug over Winter Break, run by SURGE and Eco-reps. Refer to the Student Groups link for info.
  • Exchange your bulbs on campus through the Greening Princeton Light Bulb Exchange.
