Until just three months ago, life in this humble village without electricity would come to a grinding halt after sunset. Inside his mud-and-clay home, Ganpat Jadhav's three children used to study in the dim, smoky glow of a kerosene lamp. And when their monthly fuel quota of four liters dried up in just a fortnight, they had to strain their eyes using the light from a cooking fire.
That all changed with the installation of low-cost, energy-efficient lamps that are powered entirely by the sun.
"Children can now study at night, elders can manage their chores better," says Mr. Jadhav. "Life doesn't halt anymore when darkness falls."
The innovative lights were installed by the Grameen Surya Bijli Foundation (GSBF), a Bombay-based nongovernmental organization focused on bringing light to rural India. Some 100,000 Indian villages do not yet have electricity. The GSBF lamps use LEDs - light emitting diodes - that are four times more efficient than an incandescent bulb. After a $55 installation cost, solar energy lights the lamp free of charge.
LED lighting, like cellphones, is another example of a technology whose low cost could allow the rural poor to leapfrog into the 21st century.
As many as 1.5 billion people - nearly 80 million in India alone - light their houses using kerosene as the primary lighting media. The fuel is dangerous, dirty, and - despite being subsidized - consumes nearly 4 percent of a typical rural Indian household's budget. A recent report by the Intermediate Technology Development Group suggests that indoor air pollution from such lighting media results in 1.6 million deaths worldwide every year.
LED lamps, or more specifically white LEDS, are believed to produce nearly 200 times more useful light than a kerosene lamp and almost 50 times the amount of useful light of a conventional bulb.
"This technology can light an entire rural village with less energy than that used by a single conventional 100 watt light bulb," says Dave Irvine-Halliday, a professor of electrical engineering at the University of Calgary, Canada and the founder of Light Up the World Foundation (LUTW). Founded in 1997, LUTW has used LED technology to bring light to nearly 10,000 homes in remote and disadvantaged corners of some 27 countries like India, Nepal, Sri Lanka, Bolivia, and the Philippines.
