In the Spotlight

Technologies that help businesses save energy are good for your budget and the environment. In the next few years, we'll see certain technologies move to the forefront. They might be as basic as Dell's introduction of more energy-efficient computer systems. Increased use of building automation systems will be an effective way to cut down on energy usage as well.

The Department of Energy estimates that 22 percent of electricity consumption in the U.S. goes to lighting, which makes more energy-efficient lighting an attractive area for innovation. One technology with big buzz behind it is LEDs--semiconductor devices that emit light. You can see color LEDs in applications ranging from large signage displays to cell phones; the more recent advancements are in white-light LEDs, which can be used for general illumination purposes.
