Abstract

Indonesia sits atop one of the best geothermal heat sources on the earth. Almost 50% geothermal sources placed in Indonesia. Geothermal energy could converted into electrical energy and it can provide 27.000 MW electricity if the sources all used. But, geothermal development has been minimal caused of so many problem to build geothermal power plants. Here, we will talk about the potential of geothermal and the problem to make the power plants include internal and external problem.
