In pictures: Sumba island hopes to spark renewables surge in Indonesia

While only around 30 per cent of Sumba's 650,000 people have been hooked up to the power grid, more than 50 per cent of electricity used now on the island comes from renewable sources after Dutch development organisation Hivos launched the Iconic Island project. Romeo Gacad / AFP
