Renewable energy integration for lower emission planning and achieving regional energy independence: study in Yogyakarta

Abstract

We propose and try to find a model renewable energy integration for lower emission and achieving regional energy independence. The research uses three stages. First, building an energy system model, to analyze the impact of implementing energy efficiency programs. The second stage is developing an integrated model from the energy demand and supply. Finally, arranging a mitigation scenarios to develop a low-carbon energy and achieving energy independence. Long-range Energy Alternative Planning (LEAP) software was utilized to simulate two scenarios are used to analyze energy demand and supply, namely Baseline scenarios and Mitigation scenarios. Mitigation Scenario is a combination of Energy Efficiency (EE) scenario, Fuel Substitution (FS), mode change scenario (MC), and efficient vehicle (EV) scenario and is used to analyze their impact on energy demand and GHG emissions. The results showed that mitigation scenarios can reduce energy demand by 22.86% when compared to the baseline scenario. In 2050, energy demand based on the mitigation scenario is 147.15 x 103 TJ, higher than based on the baseline scenario, which energy demand is 113.52 x 103 TJ. The cumulative of GHG emission reaches 1,369.37 x 103 Tons of CO2 Equivalent, based on the baseline scenario, can be reduced 13.54% by mitigation scenario. These results are robust. Overall, this research finding provides some possible steps to develop Yogyakarta energy independence and other regions.
