Many countries have used various strategies in the effort toward transition to alternative energy as a solution in developing renewable energy. Indonesia is the second largest producer of geothermal energy in the world. The potential of Indonesia lies in the Ring of Fire along with 117 active volcanoes, giving Indonesia high geothermal potential. This research aims to reveal and formulate the potential of geothermal as renewable energy in Indonesia as an alternative energy to be used in the future. The methods in this research are qualitative a...nd quantitative. Through the quantitative method, this research will present secondary data from various organizations as well as data from prior research on geothermal potential in the world. While qualitative method will formulate ideas of several geothermal usages from many countries by using comparison from prior research and literature from journals, books, and other publication sources. Qualitative research results will also come from in-depth interviews with stakeholders that have implemented geothermal energy in Indonesia. The result of this research will illustrate the importance of geothermal energy as an alternative renewable energy in Indonesia to replace crude oil resources as the main natural resource in Indonesia. This research recommends the mapping of resources, requiring technology as a breakthrough in processing geothermal energy to take it directly from the reservoir because of its unorthodox classification based on its source as well the cost and benefit impact on the economy related to consumer mapping to detect early the market changes of energy to geothermal.Read more
