Energy Efficiency Indicators: Fundamentals on Statistics
In 2005, the International Energy Agency (IEA) in co-operation with Eurostat launched its Energy Statistics Manual for helping statisticians to better understand the fundamentals of energy statistics and to facilitate the preparation of annual energy questionnaires. In fact, the manual was an answer to several issues, including the fast turnover of staff in offices and ministries in charge of energy statistics and the need to quickly bring up to speed newcomers in the field. The success of the manual went way beyond the initial expectation, and tens of thousands of copies of the manual in ten languages were disseminated all around the world. This certainly actively contributed to an improvement in the quality of energy statistics worldwide. Four years later, at the 2009 IEA Ministerial Meeting, ministers agreed to launch a new annual questionnaire dedicated to statistics needed to develop energy efficiency indicators. Since then, the IEA has collected energy efficiency statistics from member countries of the Organisation for Economic Co-operation and Development (OECD) on an annual basis. The data are then used for developing indicators and for feeding analyses, such as in the annual Energy Efficiency Market Report that the IEA launched in 2013.
