In Sub-Saharan Africa, and the slums of India instead they use candles, gas lamps, and open fires. Dr Evan Mills, the founder of the Lumina Project, which promotes low-carbon alternatives to fuel-based lighting. According to studies conducted by Mills and his colleagues at Berkeley Laboratory at the University of California, kerosene lamps consume 77 billion liters of fuel worldwide. If a kerosene lamp burns for four hours a day it gives off 100 kg. of carbon dioxide a year. Kerosene lamps can also cause respiratory problems. Now Mills has created a lamp that is solar powered, called the LED lamp. It burns 100 times brighter then a kerosene lamp on very low wattage.
