Physical energy flow accounts
Physical energy flow accounts (PEFA) record the flows of energy (in terajoules) from the environment to the economy (natural inputs), within the economy (products), and from the economy back to the environment (residuals).
PEFA is conceptually embedded in environmental-economic accounts. PEFA provide information on energy flows arranged in a way fully compatible with concepts, principles, and classifications of national accounts – thus enabling integrated analyses of environmental, energy and economic issues e.g. through environmental-economic modelling.
PEFA complement the traditional energy statistics, balances and derived indicators which are the main reference data source for EU energy policies.
Eurostat undertakes annual data collections with the help of the PEFA questionnaire (EXCEL). Since 2017, provision is mandatory for Member States of the EU (see Annex VI of Regulation (EU) 691/2011 consolidated version).
The annual PEFA questionnaire consists of the following five tables A to E:
Guidelines are available in the draft PEFA Manual 2014. In addition, Eurostat provides an IT-tool ('PEFA-builder') facilitating the compilation of PEFA tables A, B, and D starting from energy statistics (IEA/Eurostat annual energy questionnaires). A video tutorial explaining the use of the PEFA Builder is also available (zipped file).
PEFA data are available on Eurostat's online database.
