In view of the decreasing reliability of fossil-fuel electricity generation, its increasing costs and negative environmental side-effects, renewable energy solutions have attracted the government's attention. Together with IRENA, Tonga has charted out a renewable energy based strategy to power the main and outer islands alike. The strategy focuses on solar home systems that turn individual households into small power plants. In addition, it calls for the involvement of local operators, finance institutions and technicians to provide sustainable business models as well as strategies to ensure the effective operation, management and maintenance once the systems are installed.
