In places where electricity is scarce or unreliable, kerosene lamps are a standard lighting source—but the fumes from burning kerosene pollute the air and kill 1.6 million people each year. D.Light Design, a private company based in San Francisco, manufactures inexpensive solar-powered lamps and sells them cheaply around the world. It is safe, reliable, and renewable energy available for about the same cost as a few candles. D.Light believes that it’s not only reducing pollution, but also improving health, safety, and performance—in school, productivity, and income.
