There are more displaced people living in refugee camps and IDP camps than at any time in human history. People who live in camps have limited access to most things they need for daily life, including energy for cooking and making water safe to drink. The local energy supply is often very limited. And there are rarely sufficient funds to buy energy. Free solar energy gives people access to energy they need for cooking and water pasteurization. This is critical where the energy supply is diminished and fuel is expensive.
