Abstract

The purpose of this research is to analyze the causality between economic variables, i.e. economic growth, economic openness, and energy consumption to carbon dioxide emissions, and analyze short-run and long-run connections between research variables in Indonesia during the period 1971 to 2018. This research is using VECM analysis and Granger Causality. The results of the VECM analysis in this research show that in the short-run the variable carbon dioxide emissions in the previous period, economic openness, and energy consumption have a significant effect on carbon dioxide emissions in Indonesia, and in the long run, the variables of economic growth, economic openness, and energy consumption have a significant effect on carbon dioxide emissions in Indonesia. The Granger Causality analysis found a bidirectional causality between energy consumption and carbon dioxide emissions. It also found unidirectional causality between economic growth and carbon dioxide emissions. The recommendations that can be shared are that The Government of Indonesia should be more worried about the degradation in environmental quality in Indonesia as a result of economic development. On the other hand, in achieving sustainable economic development, the Indonesian Government must immediately use energy resources more efficiently and environmentally friendly

Abstract

AbstractThe Long-Range Energy Alternatives Planning System (LEAP) is a scenario-based energy­ environment modeling tool. LEAP as a database, it provides a comprehensive system for maintaining  energy information; as a forecasting   tool, it enables the user to make projections of energy supply and demand over a long-term planning horizan; as a policy analysis tool, it simulates and assesses the effects - physical, economic, and environmental of alternative energy programs, investments, and actions. Its scenarios are  based on comprehensive  accounting  of how energy is consumed, converted and produced  in a given region or economy under a range of alternative assumptions on population, economic development, technology, price and so on. With itsflexible data structures, LEAP allows for analysis as rich in technological specification and end-use detail as the user chooses. In this research, researcher put Indonesian case as "an intellectual exercise". However, LEAP has wide variety of projects, programs, technologies and other energy initiatives, and arrives at strategies that best address environmental and energy problems. Keywords: LEAP - energy demand - problem  tree - demand model -projection  - data structures
