An analysis of energy problems requires a comprehensive presentation of energy statistics. The Energy Data Centre (EDC) of the IEA Secretariat works closely with national administrations to collect a variety of energy statistics and compile energy balances on an annual basis for both OECD and Non-OECD countries.

For the OECD countries, supply and consumption data for renewable energy, natural gas, oil, coal, electricity and heat are collected from member countries using five annual OECD questionnaires. For Non-OECD countries, data are compiled in close collaboration with non-member country administrations, other international organisations such as UNECE, OLADE, APERC, UNSD, FAO, and draws upon the work of the United Nations in the field of global energy statistics.

From these original data, the IEA Secretariat also compiles the Energy Balances of OECD and Non-OECD countries using a specific methodology to present the data with a commune energy unit.

The EDC also compiles and presents energy demand data on a monthly and quarterly basis, energy price data, energy RD&D data, and is leading the work on effective data collection for energy efficiency indicators.
