Abstract
Energy is an element that is vital in everyday life. Its use continues to increase along with the increasing demand for energy which is influenced by population growth and economic growth. Until now, energy use is still dominated by the depletion of fossil energy, while its management is still not optimal. Energy planning needs to be done as the basis of a government policy in managing energy in order to realize national energy independence and security. This paper focuses on achieving the use of new and renewable energy according to the target of the National Energy Policy in 2025 in Java Island. Energy planning is carried out using the Computable General Equilibrium (CGE) model approach, which is an approach that can illustrate the balance between energy supply and needs. Simulations are made in the Green Energy (GREN) scenario by including several key parameters for the year of projections 2016-2025. The simulation results show an increase in the percentage of new and renewable energy use in the energy mix in 2025 by 12%. This explains that the target of National Energy Policy towards the use of new and renewable energy is reached, which is equal to 23%.Keywords: green energy, projection, LEAP, new and renewable, CGE.JEL Classifications: P18, Q43, Q47, Q48DOI: https://doi.org/10.32479/ijeep.7779
Highlights
The energy sector occupies a very vital position in daily life, both in households, industry, even at the level of commercial business
This paper focuses on the use of renewable energy, so the scenario of the Java Island energy planning used in this paper is the green energy (GREN) scenario
The energy planning model consists of primary energy, secondary energy, and energy needs
Summary
The energy sector occupies a very vital position in daily life, both in households, industry, even at the level of commercial business. Renewable energy modelling in the form of nuclear energy in Lithuania is carried out using the computational general equilibrium (CGE) method with the aim of looking at the impact of policies on nuclear energy use on economic growth and environment (Galinis and Leeuwen, 2000). The variables used are in the form of supply, consumption, foreign trade, and the environment The results of this modelling state that the policy of using nuclear energy can reduce the production of carbon emissions and increase the economic growth. Based on the literature study that has been explained, in this paper, an energy modelling using the CGE model is presented to see the effect of the equilibrium of the electricity market by considering new and renewable energy policies and making a model of long-term energy planning with Java Island general equilibrium method to streamline energy use and supply using LEAP software. The systematics of writing in this paper are as follows: Section II explains some of the basic assumptions used in modelling energy planning, Section III is the result and analysis of the results of the energy planning model, and Section IV is the conclusion
