Energy Statistics: IEA Methodology and Models
Rising global demand for adequate and reliable energy supplies makes the availability of energy statistics indispensable for formulating national energy policy and ensuring that the energy market functions effectively. An unregulated energy market does not automatically produce reliable, objective and timely statistical data that will ensure its transparency, since no single enterprise can bear the costs of maintaining a complex data system. It is therefore incumbent on state authorities to collect, verify and disseminate energy market statistics.This study highlights the key role and methodology of the International Energy Agency in the field of energy statistics. The Statistics Division of the IEA plays a predominant role, as it collects, verifies, and publishes information on energy from both OECD member countries and non-member countries. Data gathering from member countries is undertaken through established reporting systems. For non-member countries and international organizations, the customary mode for data collection is through bilateral exchange, cooperation agreements or personal contacts. An important task for the Statistics Division is to disseminate data, which is done through publications, electronic data and the Internet.
The underlying reasons for gathering energy data and the means of collection are examined, with the UK and United States serving as case studies. The authors outline the legislation relating to the collection of energy statistics, which indicates the level of government intervention in economic affairs. A corresponding issue is the degree of statistical confidentiality.
The classification of data is examined in detail for all products and all flows (or uses) of the energy. The treatment and verification process for data received by OECD member and non-member countries is also demonstrated. Finally, guidelines are provided regarding the construction of a commodity balance, the conventions of an energy balance, as well as the IEA energy balance format, which facilitates both cross-fuel and cross-country comparisons.
