Energy indicators are seen from energy elasticity and energy intensity.
Energy elasticity is the ratio between growth in energy consumption with economic growth. A smaller elasticity number indicates that a country is using its energy more efficiently. Indonesia's energy elasticity in 2009 is still quite high at 2.69. In comparison, according to International Energy Agency study in 2009, Thailand’s elasticity is 1.4, Singapore 1.1 and developed countries range from 0.1 to 0.6.
Energy intensity is the ratio between the total consumption of energy per Gross Domestic Product (GDP). The lower the intensity number, the more efficient a country is in using its energy. The intensity of primary energy in Indonesia in 2009 amounted to 565 TOE (ton-oil-equivalent) per 1 million USD. That means to increase the GDP by 1 million USD, Indonesia needs energy as much as 565 TOE. In comparison, Malaysia's energy intensity is 439 TOE/million USD and an average energy intensity for developed countries in the OECD (Organization for Economic Cooperation and Development) is only 164 TOE/million USD. Based on the above figures of energy elasticity and intensity, it is clear that energy consumption in Indonesia is still not efficient.
