Abstract | Yogyakarta does not have any non renewable energy sources such as liquid fossil fuels, coal and natural gas. Consequently, these energy resources must be supplied from other provinces. This study purposed to evaluate the existing energy demand and supply in Yogyakarta and to predict the supply and demand by empowering the use of renewable energy which meets the objective of the energy mix and energy elasticity of less than 1. The objectives of energy mix for renewable energy based on KEN and KED scenarios were 17% and 9.28% respectively in 2025. This study used a model of LEAP (Long-range Energy Alternatives Planning System) version: 2011.0.0.40. Based on KED scenario, the energy demand in Yogyakarta showed that the highest energy user sector was the transportation and the household sectors. To achieve the objectives of the elasticity ratio of energy, first by decreasing the energy consumption in transportation and electricity sectors. Transportation sector consumed 53.49% of energy but only contributed 10.69% added value to GDP. Utility sector (electricity, water and gas) used 36.41% of energy consumption, but the value added to GDP was only 0.91%. The second step was to increase economic growth in the commercial sector and agriculture. Commercial sector was the highest contributor to GDP at 23.90% but used only 4.25% of energy. The agricultural sector could provide an added value of 18.59% to GDP, but only used 0.50% of energy. With existing resources, renewable energy generation in 2011 accounted for only 0.88% of total load. In 2025 the renewable energy generation is expected to contribute to the energy mix by 5%. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
