Energy Efficiency Indicators

Energy efficiency is when something delivers more output as services or production for the same energy input, or the same services or production for less energy input. For example, when a compact florescent light (CFL) bulb uses less energy than an incandescent bulb to produce the same amount of light, the CFL is considered to be more energy efficient.

Energy efficiency indicators are useful for  policy makers to determine where energy savings can be made.

Economic and human activity, energy use and CO₂ emissions are determined by energy efficiency indicators. Many IEA member countries already employ energy indicators, a set of disaggregated measures of how energy is used. The IEA role is to assist and co-ordinate countries’ efforts through the maintenance of transparent international databases, the development of state-of-the-art energy indicators and collaboration with other international organisations.

The IEA has since 1997 developed a series of energy indicators to study energy-use developments and analyse factors behind changes in energy use and CO₂ emissions. Energy indicators (and the underlying databases) reveal key relationships between energy use, energy prices and economic activity. This insight is crucial when assessing and monitoring past and present energy policies, and for designing effective future action. This work on indicators also aims at increasing the transparency, quality, completeness and timeliness of energy-related data.
