Abstract

Indonesia has ratified 17 Sustainable Development Goals (SDG) recommended by the United Nations to all countries. The development itself cannot be carried out without the availability of electricity and fuel. Unfortunately, most of the electricity and transportation depend on fossil fuels, which will run out in the next 30 years. Besides its diminishing reserves, fossil fuels are the largest contributor to CO2 emissions in the world. To develop electricity from renewable energy, Indonesia needs to prepare its experts and operators through mid and high education to carry out research, operations and future development. This paper offers a road map for higher education and its direction of research and development in the field of renewable energy engineering.

Abstract

To face the planetary crisis, Indonesia has prioritized sustainable development through the use of green economy practices to reduce future carbon emissions. Solar energy as one of the renewable energy sources has greater value than others, but its utilisation is still small. Consideration of this condition is discussed with the aim of evaluating the progress of the green economy; finding problems; providing solutions and suggestions for Indonesia's future development. The research method uses a systematic quantitative descriptive approach based on data collected through observations, interviews and questionnaire surveys from resource persons by providing 3 leverage factors namely; funding, regulation and institutions. The study results show that the regression coefficient of the funding factor variable (X1) is 0.365 and positive, then the funding factor variable (X1) has the largest coefficient compared to the coefficient of the regulatory factor (X2) and the institutional factor (X3), so that the funding factor is the most dominant factor in measuring the performance of solar energy success towards the implementation of the green economy. Without serious support from the government in terms of funding readiness, development goals will not be achieved, due to the large amount of funds needed to support the development of the Green Economy. However, the three variables are mutually sustainable by making policies and legal foundations to fulfil the funding needs of the green economy, regulations will be the foundation in mainstreaming the implementation and funding of green economy policies. Green economy planning, governance and supervision are supported by mature institutions and funds

Abstract

The increasing demand for electrical energy in Indonesia, driven by rapid economic growth, necessitates a comprehensive evaluation of the country’s electrical energy security across four critical aspects: availability, accessibility, acceptability, and affordability. Despite significant expansion in power generation capacity, with coal-fired plants still dominating the energy mix, environmental concerns regarding emissions pose major challenges to sustainability. This study aims to analyze Indonesia’s electrical energy security by quantitatively assessing 20 key indicators from 2008 to 2023 and projecting trends to 2030 and 2045. Employing data normalization and a rhombus area graphical model, the research integrates multi-dimensional data to provide a holistic security index. Results reveal improvements in availability, accessibility, and affordability over time, but acceptability declines due to rising greenhouse gas emissions, underscoring the environmental trade-offs of fossil fuel reliance. The findings highlight the urgent need for policy and technological interventions such as expanding renewable energy, implementing Carbon Capture and Storage (CCS) technologies, and promoting electrification of industrial and transport sectors. This study offers crucial insights for policymakers and stakeholders to balance energy growth with environmental sustainability, guiding Indonesia towards a secure and cleaner energy future.
