Citizens of Gaza typically have 12 hours of power per day, at best. During periods of political disagreement or military conflict, this is reduced even more to as little as 2 hours per day. Hospitals, schools, and other critical facilities are struggling to function. The World Bank study "Securing Energy for Development (SED) " examines the different alternatives, including solar energy, that could offer a reliable power supply to Gaza. The study was supported by the World Bank’s Energy Sector Management Assistance Program (ESMAP).
