<P> The European Environmental Agency (EEA) measures final energy consumption (does not include energy used in production and lost in transportation) and finds that the transport sector is responsible for 31.8% of final energy consumption, households 26.2%, industry 25.6%, services 13.5% and agriculture 2.9% in 2012 . The use of energy is responsible for the majority of greenhouse gas emissions (79%), with the energy sector representing 31%, transport 19%, industry 13%, households 9% and others 7% . </P> <P> While efficient energy use and resource efficiency are growing as public policy issues, more than 70% of coal plants in the European Union are more than 20 years old and operate at an efficiency level of between 32--40% . Technological developments in the 1990s have allowed efficiencies in the range of 40--45% at newer plants . However, according to an impact assessment by the European Commission, this is still below the best available technological (BAT) efficiency levels of 46--49% . With gas - fired power plants the average efficiency is 52% compared to 58--59% with best available technology (BAT), and gas and oil boiler plants operate at average 36% efficiency (BAT delivers 47%). According to that same impact assessment by the European Commission, raising the efficiency of all new plants and the majority of existing plants, through the setting of authorisation and permit conditions, to an average generation efficiency of 51.5% in 2020 would lead to a reduction in annual consumption of 15 km (3.6 cu mi) of natural gas and 25 Mt (25,000,000 long tons; 28,000,000 short tons) of coal . </P>
