Even the choice you make in the bulb you use in your desk lamp can make a big difference, especially when you add up the impact of hundreds of dorm rooms. Choose an LED for 90% savings over a traditional incandescent bulb, which will radiate this energy as heat. LEDs therefore reduce the cooling load required in your room, without the worries of mercury content that exist with compact fluorescents.
A quality LED can also last up to 20 years. Look for Energy Star-certified bulbs and products to get the peace of mind backed by industry testing and verification.
