Furthermore, Indonesia plans to realise its estimated 29 GW of geothermal potential, from the installed capacity of 1.3 GW in 2013. Indonesia has considerable further potential for biomass amounting to 13 GW of electrical output, of which less than 0.08 GW had been exploited in 2012. Because of their geographical constraints, Singapore’s and Brunei Darussalam’s technical potential for renewable energy is more limited, although Singapore is targeting a rapid development of solar PV.
