Efficient lighting designs are used in only a small minority of spaces, and control systems that maximize the use of daylight are even less common. No comprehensive studies of potential, overall peak load reduction from more efficient commercial lighting exist. However, estimates by the American Council for an Energy Efficient Economy suggest the savings by 2010 could be as high as 20,000 megawatts. This is more than 10 percent of planned generating capacity additions by 2010. Education and promotion programs offered by utilities, local governments and lighting designers and manufacturers can help encourage the use of more efficient lighting systems.
Utilities can also offer incentives for efficient equipment and designs.
For example, New England Electric offers programs to encourage more efficient lighting in both new and existing buildings. A third program specifically targets small businesses with a comprehensive package of lighting retrofits.
