Alternative Energies Title: Farmers Foil Utilities Using Cell Phones to Access Solar snip In October, Bangalore-based Simpa Networks Inc. installed a solar panel on Anand’s whitewashed adobe house along with a small metal box in his living room to monitor electricity usage. The 25-year-old rice farmer, who goes by one name, purchases energy credits to unlock the system via his mobile phone on a pay-as-you-go model. When his balance runs low, Anand pays 50 rupees ($1) -- money he would have otherwise spent on kerosene. Then he receives a text message with a code to punch into the box, giving him about another week of electric light. When he pays off the full cost of the system in about three years, it will be unlocked and he will get free power. snip Electricity Revolution “Things are much easier now,” Anand says, describing how he used to go through 5 liters (1 gallon) of fuel a month, almost half of it bought from the black market at four times the price of government kerosene rations. “There was never enough.” Anand is on the crest of an electricity revolution that’s sweeping through power markets and threatening traditional utilities’ dominance of the world’s supply. From the poorest parts of Africa and Asia to the most- developed regions in the U.S. and Europe, solar units such as Anand’s and small-scale wind and biomass generators promise to extend access to power to more people than ever before. In the developing world, they’re slashing costs in the process. Across India and Africa, startups and mobile phone companies are developing so-called microgrids, in which stand- alone generators power clusters of homes and businesses in places where electric utilities have never operated. snip ‘Second Great Leapfrog’ In parts of Africa, the poor, lacking electricity, buy power in the form of batteries, kerosene and candles; in effect, they’re paying as much as $4 per kilowatt-hour, according to Vijay Modi, a Columbia University professor who heads the SharedSolar project. That’s about 66 times what a resident of Manhattan is charged for electricity. Simpa co-founder Paul Needham says filling the power gap will entail a transformation similar to the one in which mobile phones bypassed traditional landlines to deliver telecommunications services to vast populations in India and Africa. “What we’re seeing is the beginning of the second great leapfrog story,” says Needham, who estimates that 1.6 billion people in the world don’t have access to electricity.
