Energy Efficiency in Indonesia
With vast economic growth and population growth, Indonesia has the interest to manage and use energy as effectively and as efficiently as possible. According to the World Bank, Indonesia's economic growth increased from 5.7% in 2005 to 5.9% in 2010, and is projected to reach 6.2% in 2011. While the population of Indonesia, which now reaches up to 229 million people are expected to increase to more than 230 million in 2011.
All of this growth is surely accompanied by the increase in energy demand due to the increasing number of homes, factories, and commercial and industrial buildings. If we assume that demand for electricity will grow in average 7% per year for the next 30 years, then electricity consumption will significantly increase, for example in the household sector, consumption will increase from 21.52 GWh in 2000 to around 444.53 GWh in 2030.
There are four main sectors of energy users, namely household, commercial, industrial and transportation sector. Currently the largest energy user is the industrial sector with a share of 44.2%. Next largest consumption is the transportation sector with 40.6%, followed by the household sector with 11.4% and the commercial sector with 3.7%.
Until now, the primary sources of energy still come from fossil fuels, with 46.9% from oil, 26.4% from coal, and 21.9% from natural gas. Hydro (water) power and other renewable energy only make up about 4.8% from the total of utilized energy resources.
