Economic development depends on the availability of energy, especially in supporting the current government’s development priorities to build the infrastructure sector in Indonesia, while the goal of development is to improve the nation’s competitiveness this research aims to investigate the opportunity to reduce fossil energy and switch to renewable energy. One of the efforts to improve long-term national energy security length is through reducing dependence on fossil energy, and the government must take swift action to use renewable energy. The methodology in this research uses internal factor evaluation analysis, external factor evaluation and SWOT matrix. Furthermore, the data used is secondary data in the period 2017–2022 coming from various official sources. The development of renewable energy in the world followed by the technology, more advanced technology used, the cost of investment and renewable energy tariffs will be cheaper, thus will be more competitive with electricity from fossil energy. Currently the installed power generation capacity in Indonesia is 57 gigawatts, of which 86% still use fossil energy and the remaining is renewable energy. Renewable energy in Indonesia becomes a very potent alternative, where the energy source depends on the geographical area and the source of energy it produces. The potential of renewable energy in Indonesia is very big, Indonesia has 40% geothermal potential in the world.
