The rising usage of fossil fuels increases greenhouse gas (GHG) emissions, leading to global climate change. Thus, addressing global environmental challenges requires a widespread switch from fossil fuels to renewable energy. Renewable energy reduces GHG emissions, extreme weather, and climate change while boosting energy efficiency. Indonesia ranks among Asia-Pacific's top five renewable energy producers. Indonesia, a vast country with abundant natural resources, has seen a rise in renewable energy demand as consumption has increased. Thus, this study examines Indonesia's renewable and sustainable energy technologies' existing position, possibilities, and future improvements. With 420 gigawatts (GW) of theoretical renewable energy capacity, Indonesia has great potential. This capacity includes 208 GW of solar, 75 GW of hydro, 61 GW of wind, 33 GW of biofuel, 24 GW of geothermal, and 19 GW of micro-hydro. The need to increase renewable energy consumption in Indonesia is driven by environmental and economic growth laws. This review study is expected to guide future research on renewable energy technology in Indonesia. This study would guide energy-related policies, particularly renewable energy ones, to meet future demands and goals.
