Turn off the lights, stereo, TV or other electrical devices in your room when leaving for more than one minute. TVs and VCRs consume energy even when they are turned off. If possible, unplug your TV or VCR.
Use compact florescent bulbs for task lighting. They deliver the same light as incandescent bulbs for 75 percent less energy. They cost more upfront but last up to 10 times longer. Turn off your overhead light to save energy also.
