Huge Potential of Geothermal Energy in Indonesia

Heat energy of the earth or geothermal energy become one source of renewable energy who believed as a huge and environmentally friendly. Indonesia even being a country which the bigger thermal energy with 40 % potential of thermal energy earth in the world. Unfortunately, the size of the reserve earth heat in Indonesia yet to be in full.And Indonesia still depends on the energy source of the fossil. Heat energy the earth or geothermal energy is energy thermal ( heat ) are generated and stored in the earth. Geothermal comes from the greek " geo " which means " the earth "and " term " which means Color or heat. Energy resulting from activity tectonics taking place in the earth. In addition, it could also be derived from the heat the sun absorbed by the surface of the earth.Further, the process of the establishment of the heat energy the earth ( geothermal ) is precipitated by events tectonics into the earth. The nucleus of the earth having of magma.

Further, the process of the establishment of the heat energy earth ( geothermal ) is precipitated by events tectonics into the earth.The nucleus the earth having of magma temperature reached 5.400 degrees centigrade. Magma makes a layer of the earth increased temperature. When this layer touch with water it will become hot vapor high-pressure. This is potential energy that then known as heat energy the earth or geothermal energy. Energy consumption earth heat believed to be one of alternative energy sources. Excess energy that it is the first, earth heat is one source of clean energy. Second, is the type of renewable energy relatively not be exhausted. Third, environmentally friendly who do not causes pollution of ( both air pollution, pollution sound, and not producing carbon emissions and gas, a liquid, and material poisonous other. Fourth, compared with alternative energy such as solar and the wind where the energy sources are constantly all season.

Potential and the utilization of heat energy the earth in Indonesia talk about potential, Indonesia has potential energy earth heat (geothermal great. According to data from PT. Pertamina Geothermal Energy (pge.pertamina.com ), Indonesia has 40 % of all the potential here earth heat in the world. Sources are spread in 251 location Sumatra, java, Nusa Tenggara, Maluku, up to the end of west Papua. The ministry ( 2013 predicted the whole capacity reserve and resources heat energy the earth in Indonesia reach 28.994 MWe ( megawatts of electricity ). The amount of energy the, if using fuel, equivalent more than 200 billion barrels of oil.

Huge potential of geothermal energy in Indonesia approximately just four percent that have been used by Geothermal power plant that have opened in Indonesia like Sibayak Geothermal Power Plant in North Sumatra, Salak Geothermal Power Plant ( west java ) , Dieng Geothermal Power Plant ( central java ), and Lahendong Geothermal Power Plant ( North Sulawesi ) . So unfortunate if the potential earth heat such the size, could not use maximum by Indonesia.Indonesia still preferring to choose the source of energy fossil fuel cell to have a huge impact on global warming, and it was not enough to national energy needs. And unuseful 28.9 thousand MW energy sources continuity and environmentally friendly provided by earth heat.
