Eva Walusimbi knows well how it is to live in darkness. As a community leader in the small town of Mityana, central Uganda, she's been witnessing the health hazards and financial strains that a shortage of electricity can bring to people living in energy poor, rural areas. In Uganda, some 90% of the population lives without access to electricity, according to World Bank figures. Apart from the health risks, Walusimbi, 50, says that lack of electricity is also preventing people from escaping poverty. People that are living without electricity, their day ends up so quickly -- they can do less work compared to the people with full light," she says. But for Walusimbi, there is light at the end of the tunnel. She has joined Solar Sister, a group aiming to eradicate energy poverty while creating economic opportunities for women. Solar Sister trains, recruits and supports female entrepreneurs in East Africa to sell affordable solar lighting and other green products such as solar lamps and mobile phone chargers. The women use their community networks of family and neighbors to build their own businesses, earning a commission on each sale. Solar Sister founder Katherine Lucey, a former investment banker with expertise in the energy sector, says this model is creating access to safe, affordable and clean energy while helping women to earn a steady income to support their families.
