East Java is one of the provinces in Indonesia that has many potential renewable energy sources to be developed in order to support Indonesia's energy security. The potential for renewable energy in East Java is very large, so good management is needed. Energy potential as a national vital object in East Java is meant such as Geothermal and Hydroelectric Power Plants (PLTA). Although dependence on the use of fossil energy is still high, the Provincial Government of East Java has entered an era of energy transition, namely the transition from fossil energy to a new renewable energy system. This is because the potential availability of fossil energy is dwindling while people's needs are increasing. Therefore, an alternative is needed to maintain energy security in the availability of energy to meet the needs of the community, namely renewable energy. In addition, the transition to renewable energy is one of the agendas in helping the government to achieve the Net Zero Emission goal because new and renewable energy is categorized as green energy that is environmentally friendly so that it can minimize the threat of greenhouse gas effects and reduce emissions. This research was conducted using a qualitative descriptive method by conducting interviews from research sources and supported by literature sources. With this, it is hoped that the results of this research can be used as guidelines by other local governments in optimizing the potential of renewable energy.
