Progress on energy efficiency in Europe The ODEX index measures progress in energy efficiency by major sector (industry, transport, households and services), as well as for all final consumers. For each sector, the index is calculated as a weighted average of sub-sectoral indices of progress in energy efficiency, observed over a given period. Sub-sectors refer to industrial or service sector branches or end-uses for households or transport modes. The sub-sectoral indices are calculated from variations of unit energy consumption indicators, measured in physical units (for instance tons of steel, tonne-km for transport of goods, kWh/appliance, m² for offices, etc.). ODEX provides a better 'proxy' of energy efficiency progress from a policy evaluation viewpoint than the more commonly used monetary indicators.
Overview of the European energy system Energy efficiency of conventional thermal electricity production Output from conventional thermal power stations consists of gross electricity generation and any heat sold to third parties (combined heat and power plants) by both conventional thermal public utility power stations and autoproducer thermal power stations. The energy efficiency of conventional thermal electricity production (which includes both public plants and autoproducers) is defined as the ratio of electricity and heat production to the energy input as fuel. Fuels include solid fuels (i.e. coal, lignite and equivalents, oil and other liquid hydrocarbons, gas, thermal renewables, industrial and municipal waste, wood waste, biogas and geothermal energy) and other non-renewable waste. Energy losses in transformation and distribution Numerator: The amount of energy loss is the sum of the the energy industry's own consumption, with distribution and transformation losses (the difference between transformation input and output).  Denominator: Numerator plus final energy available for final consumption in primary energy. EU-28 share of primary energy by fuel type and share of final energy consumption by sector Total energy consumption or gross inland energy consumption represents the quantity of energy necessary to satisfy the inland consumption of a country. It is calculated as the sum of the gross inland consumption of energy from solid fuels, oil, gas, nuclear and renewable sources, and a small component of ‘other’ sources (industrial waste and net imports of electricity). The relative contribution of a specific fuel is measured by the ratio between the energy consumption originating from that specific fuel and the total gross inland energy consumption calculated for a calendar year.
Intensity of final energy consumption This indicator measures final energy consumption, which covers energy supplied to the final consumer for all energy uses. It is calculated as the sum of the final energy consumption of all end-use sectors. These sectors are disaggregated to cover the industry, transport, households, services and agriculture sectors. Total final energy intensity is defined as total final energy consumption (consumption of transformed energy, i.e. electricity, publicly supplied heat, refined oil products, coke, etc., and the direct use of primary fuels such as gas or renewables, e.g. solar heat or biomass) divided by GDP at 2010 prices. For a comparison of GDP and final energy intensity in a year between countries, the GDP figures can be taken at purchasing power parity (PPP) to eliminate the differences in price levels, allowing meaningful volume comparisons of GDP figures between countries. Households energy intensity is defined as final households energy consumption divided by population. Transport energy intensity is defined as final transport energy consumption divided by GDP at 2010 prices in billions of euros. Industry energy intensity is defined as final industry energy consumption divided by industry gross value added (GVA) at constant 2005 prices. This excludes final energy consumption and GVA from construction. Services energy intensity is defined as final services energy consumption divided by services GVA at constant 2005 prices. The value added of services is the sum of the following seven values added: wholesale and retail trade, transport, accommodation and food service activities; information and communication activities; financial and insurance activities; real estate activities; professional, scientific and technical activities; administrative and support service activities; public administration, defence, education, human health and social work activities; arts, entertainment and recreation; other service activities; activities of household and extra-territorial organisations and bodies. Agriculture and fisheries energy intensity is defined as final agriculture and fisheries energy consumption divided by agriculture, forestry and fishing GVA at constant 2005 prices.
Final energy consumption intensity   Final energy consumption covers energy supplied to the final consumer for all energy uses. It is calculated as the sum of final energy consumption of all sectors.

Total final energy intensity is defined as total final energy consumption (consumption of transformed energy such as electricity, publicly supplied heat, refined oil products, coke, etc., and the direct use of primary fuels such as gas or renewables, e.g. solar heat or biomass) divided by gross domestic product (GDP) at constant 2005 prices. The GDP figures are taken at constant prices to avoid the impact of inflation, base year 2005. Household energy intensity is defined as household final energy consumption divided by population. Transport energy intensity is defined as transport final energy consumption divided by GDP at constant 2005 prices. Industry energy intensity is defined as industry final energy consumption divided by industry Gross Value Added at constant 2005 prices. This excludes final energy consumption and gross value added from construction.  Services energy intensity is defined as services final energy consumption divided by services Gross Value Added at constant 2005 prices. Value added of services is the sum of 3 value added : G_H_I : Wholesale and retail trade, repair of motor vehicles, motorcycles and personal and household goods; hotels and restaurants; transport, storage and communication, J_K - Financial intermediation; real estate, renting and business activities and L_TO_P - Public administration and defence, compulsory social security; education; health and social work; other community, social and personal service activities; private households with employed persons
Progress on energy efficiency in Europe The ODEX index (Figure 1) measures energy efficiency progress by the main sectors (industry, transport and households), as well as for the whole economy (all final consumers). For each sector, the index is calculated as a weighted average of sub-sectoral indices of energy efficiency progress; the sub-sectors are the industrial or service sector branches or end-uses for households or transport modes. The sub-sectoral indices are calculated from variations of unit energy consumption indicators, measured in physical units and selected so as to provide the best “proxy” of energy efficiency progress from a policy evaluation viewpoint. The fact that indices are used enables different units to be combined for a given sector, for instance, for households kWh per appliance, koe/m 2 , tep per dwelling etc. The weight used to get a weighted aggregate is the share of each sub-sector in the total energy consumption of the sub–sectors considered in the calculation.  A value of ODEX equal to 90 means a 10 % energy efficiency gain. The variation of the specific consumption of space heating per dwelling linked to building standards is modelled as the change brought about by the introduction of new dwellings with better insulation than the whole stock, since a base year (e.g. 1990), assuming that the unit consumption of new dwellings is equal to the theoretical value implied by thermal regulations (Figure 2). This effect is calculated as follows: ∆UCnew t = (UCnew t * nbrlpn t + ∆UCnew t-1 * (nbrlpr t – nbrlpn t )) / nbrlpr t with:  ∆UCnew t=0 = ∆UCnew t=1990 = UC t=1990 nbrlpr t : stock of dwellings at year t nbrlpn t : the volume of construction at year t   UC t : unit consumption per dwelling for space heating at year t
Overview of the European energy system Gross inland consumption is calculated as follows: primary production + recovered products + total imports + variations of stocks - total exports - bunkers. It corresponds to the addition of final consumption, distribution losses, transformation losses and statistical differences.
Primary energy consumption by fuel Primary energy consumption is defined as gross inland energy consumption minus the energy consumed for purposes other then producing useful energy (non-energy use). Gross inland energy consumption represents the quantity of energy necessary to satisfy the inland consumption of a country. It is calculated as the sum of the gross inland consumption of energy from solid fuels, oil, gas, nuclear and renewable sources, and a small component of ‘other’ sources (industrial waste and net imports of electricity). The relative contribution of a specific fuel is measured by the ratio between the energy consumption originating from that specific fuel and the total primary energy consumption calculated for a calendar year.
Overview of the European energy system Energy flows in European Union The Sankey diagram (Fig.1) shows the energy conversion from primary energy (coal, oil, natural gas, etc) to secondary energy commodities such as heat, electricity and manufactured fuels, through transformation plants (power stations, district heating, CHPs, oil refineries and other transformation plants) and the associated conversion losses. The right hand side of the diagram shows the final mix of energy consumption by different EU27 energy users (including: industry, transport, domestic, other final consumers and non-energy use). Note that renewables in transport for ENER 36 include all biofuels whether sustainable or not. Only a proportion of the primary energy entering the energy system of a country flows through to the end user for consumption.  There are various diversions and losses incurred before energy reaches the final consumer due to distribution losses and use in the energy sector. The Sankey diagram is useful in capturing the situation in a certain year but other indicators are needed to show the change in energy use over time. Energy efficiency of conventional thermal electricity and heat production Output from conventional thermal stations consists of gross electricity generation and also of any heat sold to third parties (combined heat and power plants) by conventional thermal public utility power stations as well as autoproducer thermal power stations. The energy efficiency of conventional thermal electricity production (which includes both public plants and autoproducers) is defined as the ratio of electricity and heat production to the energy input as a fuel. Fuels include solid fuels (i.e. coal, lignite and equivalents, oil and other liquid hydrocarbons, gas, thermal renewables (industrial and municipal waste, wood waste, biogas and geothermal energy) and other non-renewable waste. Units: Fuel input and electrical and heat output are measured in thousand tonnes of oil equivalent (ktoe). Efficiency is measured as the ratio of fuel output to input (%) Energy losses in transformation and distribution Numerator: Share of energy losses is the sum of own consumption of the energy industry, distribution losses and transformation losses (difference between transformation input and output). Denominator: Numerator plus final energy available for final consumption in primary energy. EU-27 Share of primary energy by fuel type and, share of final energy consumption by sector Total energy consumption or gross inland energy consumption represents the quantity of energy necessary to satisfy the inland consumption of a country. It is calculated as the sum of the gross inland consumption of energy from solid fuels, oil, gas, nuclear and renewable sources, and a small component of ‘other’ sources (industrial waste and net imports of electricity). The relative contribution of a specific fuel is measured by the ratio between the energy consumption originating from that specific fuel and the total gross inland energy consumption calculated for a calendar year (Fig.2). Units: Energy consumption is measured in thousand tonnes of oil equivalent (ktoe). The share of each fuel in total energy consumption is presented in the form of a percentage. EU27 net energy imports of solid fuels, oil, and gas from outside the EU27 was calculated as follows: total imports by fuel minus the sum of imports by fuel from other EU Member States minus total exports (Fig.1)

Total Gross Inland Consumption by Fuel The structure of the energy mix in gross inland energy consumption provides an indication of the environmental pressures associated with energy consumption. The type and magnitude of the environmental impacts associated with energy consumption, such as resource depletion, greenhouse gas emissions, air pollutant emissions, water pollution, accumulation of radioactive waste, etc., strongly depend on the type and amount of fuel consumed as well as abatement technologies applied.
