Geothermal power in the Philippines is the country's second largest source of renewable energy, and the fifth largest source of energy overall. Among sources of renewable energy, it is second only to hydroelectric power, although both sources are surpassed by the amount of energy drawn from coal, oil, and natural gas in that order.[1]
The Philippines is one of the world's top producers of geothermal power, owing to its location along the Ring of Fire zone of Pacific volcanoes.[2] The Geothermal Education Office and a 1980 article titled "The Philippines geothermal success story" by Rudolph J. Birsic published in the journal Geothermal Energy noted the remarkable geothermal resources of the Philippines.[3][4] During the World Geothermal Congress 2000 held in Beppu, Ōita Prefecture of Japan held from May to June 2000, it was reported that the Philippines is the largest consumer of electricity from geothermal sources and highlighted the potential role of geothermal energy in providing energy needs for developing countries.[5]
According to a 2015 study by Bertani, the Philippines ranks second to the United States worldwide in producing geothermal energy. The study notes that in 2015, the US had a capacity of 3450 megawatts from geothermal power, while the Philippines had a capacity of 1870 megawatts. The Philippines was then followed by Indonesia, which had 1340 MWe.[6]
Early statistics from the Institute for Green Resources and Environment stated that Philippine geothermal energy provides 16% of the country's electricity.[7] By 2005, geothermal energy accounted for 17.5% of the country's electricity production.[8] More recent statistics from the IGA show that combined energy from the nation's six geothermal fields, located in the islands of Luzon, Leyte, Negros and Mindanao, still accounts for approximately 17% of the country's electricity generation.
