Abstract

The transportation sector is the second largest final energy consumer after the industry sector. The main energy issue in the transportation sector in Indonesia is the dominant use of oil fuels. Moreover, almost 60% of total oil fuels are being subsidized. On the contrary, the development and application of New and Renwable Energy (NRE) in the transportation sector has not been very successful. This paper applies the Analytical Hirarchy Process (AHP) in conjuction with optimization of the energy system using MARKAL model to select the best strategy for increasing the role of New and Renewable Energy (NRE) in the transportation sector. Three case studies are applied to evaluate the intervention by policy as an effort to increase the role of NRE in the transportation sector.

Abstract

As the energy consumption continues to increase, while, the most of the energy consumption is met from oil, and the oil supply is going to limited; energy diversification is needed. Ethanol can be used as an option for the energy diversification. Ethanol is a renewable energy and environmentally friendly fuel which used as an energy alternative in the transportation sector can reduce the gasoline consumption. As gasoline is one of subsidized fuels and imported fuel, reducing gasoline consumption has also impact on reducing oil subsidy and import. As the ethanol has lower greenhouse gas of CO2, and pollutant emissions of CO, NOx, SO2, and particulate matters, ethanol utilization for energy is safe for human health and environment. Ethanol also has higher octane number and oxygen content that lead to better performance of the fuel and vehicle. Ethanol fuel program is also more creating job opportunities.
