Having reliable data and indicators on how energy is used is key to informing and monitoring the effectiveness of energy efficiency policies. Highlighting the importance of such data, the IEA has for the first time published an Energy Efficiency Indicators database with annual data from 2000 to 2015.
The database covers end use energy consumption for 8 energy products and includes end use energy efficiency indicators and carbon intensity indicators for 4 sectors (residential, services, industry and transport) for IEA member countries. These indicators are computed by using key sectorial activity data.
This comprehensive and disaggregated database provides valuable insights on the patterns of energy consumption at country level, and enables countries to keep track of efficiency improvements across sectors and end uses.
The key sectors for tracking energy efficiency progress are transport, services, manufacturing and the residential sector. Across IEA countries, the transport sector accounted for the highest share of final energy consumption in 2014 (34%), followed by manufacturing industry (27%), the residential sector (19%) and finally the services sector (14%).
