Electricity plays an important role in our daily lives. We use electricity for many purposes from lighting rooms and cooking to working appliances such as refrigerators, computers, and vide games.  However, there are about 1.2 billion people who have to live without electricity in the world. They use candles and kerosene lamps for lighting and firewood and coals for cooking. The use of those fuels has been the main reason of indoor air pollutions.  Indoor air pollution kills about 2 million people in a year.
