Instead of a traditional cathode ray tube (CRT) desktop computer monitor, get a more energy efficient "flat panel" LCD (liquid crystal display).
These days, most new computers are being sold with LCD monitors, except for high-end graphics packages and bargain models. That's a good thing, because LCDs are up to 66% more energy efficient than CRTs, according to the U.S. Department of Energy. LCDs are also upwards of 80% smaller in size and weight, leading to fuel savings in shipping. LCDs produce less heat, meaning you'll need less AC to keep cool.
LCD screens are also easier on the eyes. Their lower intensity and steady light pattern result in less fatigue versus CRTs.
Don't forget to make sure any new computer equipment you buy meets the EPA's Energy Star requirements, which now require that 80 percent of the power consumed actually be used by the computer.
