A bright investment.

Worldwide sales of compact fluorescent lights increased 23 percent last year -- to 134 million bulbs. Their substitution for standard, incandescent lights should annually save up to 6,000 megawatts of electricity, notes David M. Roodman in "Vital Signs 1993," a report released this month by the Worldwatch Institute in Washington, D.C. That's a savings equivalent to the annual energy output of 10 large, coal-fired power plants or about seven average nuclear plants.

Even at $15 to $20 each, these fluorescent bulbs should more than pay for themselves in energy savings. Roodman estimates. At the average cost of electricity in the United States of 8 cents per kilowatt hour, a compact fluorescent used three hours daily "will eventually save the buyer $35, even accounting for the lost income from not putting the money into long-term savings," he estimates. In Japan, where electricity costs 13 cents per kilowatt hour, Roodman estimates each bulb would eventually save consumers $55.
