The study by CORE Indonesia shows that the energy transition—the shift from emission-intensive fossil fuels to renewable alternatives—is crucial for mitigating climate change, addressing supply constraints, and enhancing energy security and competitiveness. Fossil fuels, particularly coal (40.35% of global source of power), necessitate this transition to prevent environmental degradation and depletion of non-renewable reserves. Transitioning to sources like solar and geothermal also yields substantial economic benefits, potentially generating 42 million green jobs by 2050, thus demanding accelerated global implementation.
