Data source(s) used: The main sources are the National Energy Balance and the IEA/Eurostat/UNECE Energy Questionnaires compiled by the Ministry of economic development (MISE). They are used jointly and complemented by other sources in order to ensure consistency with national economic accounts, to provide more accurate estimates of some aggregates, to ensure the compliance with the residence principle, to allow the breakdown by industry and type of use of energy flows measured by the PEFA. These sources are as follows:- Surveys on Foreign trade of Goods and Services, Survey on Air Transport, Production matrix at current prices, Agriculture economic accounts, Household consumption, produced by Istat; - Survey on international merchandise transport, Survey on international tourism by Bank of Italy;- Survey on Enterprises Final Consumption of Energy Products (COEN) carried out by Istat, ENEA and MISE;- Electricity balance and data on Consumption of electricity by type of activity produced by TERNA (Operator of electricity transmission grids);- Italian vehicle register provided by ACI (Italian automobile association);- Economic, energy and oil statistics produced by Unione Petrolifera;- Road freight transport measurement published on Eurostat datawarehouse;- Air emission inventory by ISPRA (Institute for Environmental Protection and Research).
Other data characteristics: PEFA differ from other energy statistics, e.g. National energy balance, for the following characteristics:- the extension of the description of physical energy flows to flows between the natural environment and the economy. PEFA record, in fact, both the energy captured or extracted by economic units directly from natural energy inputs (flows from the environment into the economy), and the energy discarded, discharged or emitted to the environment (flows from the economy to the environment);- the compilation according to the residence principle. PEFA record all energy flows associated with activities of resident units, regardless where these activities actually take place geographically. Therefore, energy flows associated with resident unit's activities abroad have to be taken into account, e.g. the purchase of fuels abroad by resident units for international transport activities (maritime, air and land) and by households temporarily abroad using own or rented vehicles. Conversely, the energy flows associated with non-resident's activities on the territory have to be excluded, e.g. energy flows due to the purchase of fuels on Italian territory by non-resident units;- the use of the main conceptual categories of the economic analysis in conjunction with the technical categories. In particular, data are organized according to the concepts of accumulation, exchange with the rest of the world (import/export), production, intermediate consumption and final consumption of the national accounts, using, for the the producers, the same classification of economic activities used in the national accounts (NACE Rev. 2);- the use of the accounting framework of Supply and Use tables (SUTs) derived from national accounts. In PEFA, the SUT framework has been extended by additional rows and columns in order to accommodate physical flows between economy and environment. Furthermore, energy products are disaggregated in order to allow detailed analysis.: Terajoules.
