Electricity shortage is a major problem around the world especially in the continents of Asia and Africa. Some rural regions are still deprived of electricity and about 1.5 billion people are dependent on kerosene lamps. However, a Chicago-based company known as the Greenlight Planet has taken the initiative to help this large population of off-grid villagers by providing them with affordable and safe solar-powered lamps. The company was founded back in 2009 and since then it has sold 1.8 million solar lamps. Costing between $11 and $40, about one million of these lamps were sold during the last 10 months only. The company hopes to sell 4 million lamps this year and expects to reach 16 million homes by 2016.
