Low-Cost Lamps Light Rural India

Until three months ago, life in this humble village without electricity would come to a 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, when their monthly fuel quota of four litres 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. The lights were installed by the Grameen Surya Bijli Foundation (GSBF), an Indian non-governmental organisation 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 a normal bulb. After a $55 installation cost, solar energy lights the lamp free of charge. LED lighting, like cell phones, is another example of a technology whose low cost could allow the rural poor to leap 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 subsidised - consumes nearly four per cent 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…
