Solar radiation is the lifeblood of the earth.
Every day, the sun emits enough energy to sustain billions of plants
and animals. Everything from the tiniest skin cell to the tallest
mountain is dependent on its daily rise and fall, and the same sun
rises in New York City as sets in New Delhi. And every hour that sun
provides enough energy to power every city, village and home on the
planet.
Because the sun is always shining somewhere, and because it knows no prejudice or hierarchy, solar power is as useful in the wealthy and insulated First World as in the stark and shortchanged Third World. In fact, many developing countries, especially those in Africa and Asia, have some of the best solar insulation in the world. In homes and villages far from transmission cables, fresh water and hospitals, the appeal of wireless, renewable energy is all the greater.
Solar power is already having some effect on the developing world. Solar lanterns are being used in India to read and study after dark. Students in Uganda are learning under solar rooftops. And communities in South America are drinking safe, potable water from solar-powered pumps. Much of these initial successes are thanks to individuals and nonprofit groups aiming to spread the solar wealth. Solar Aid and Solar Electric Light Fund (SELF) are two organizations leading in that fight.
Products that have been developed for use in the Third World, or
would be useful there, include solar flashlights, lanterns, water
pumps, panels, refrigerators and solar ovens.
