Delež električne energije iz obnovljivih virov v bruto porabi električne energije je razmerje med količino električne energije proizvedene iz obnovljivih virov in bruto porabo električne energije. Bruto poraba električne energije je enako proizvedena električna energija plus uvoz minus izvoz električne energije. Kazalnik je povzet iz Direktive 2001/77/EC o promociji električne energije proizvedene iz obnovljivih virov. Energetska intenzivnost je razmerje med količino energije (oskrba z energijo ali končna poraba energije) in bruto domačim proizvodom, izraženim v stalnih cenah. Energetska intenzivnost se manjša z izboljšanjem energetske učinkovitosti. Energetska odvisnost je razmerje med neto uvozom (uvoz izvoz) in oskrbo z energijo na nivoju države. Meri odvisnost države od uvoza energije. Energetska raba je skupna poraba električne energije in goriv za pogon, notranji transport, ogrevanje delovnih in pisarniških prostorov, poraba tople vode in pare za pogon in tehnološke procese. Energetska učinkovitost je razmerje med končno porabo energije in oskrbo z energijo. Energetski sektor obsega porabo goriv in energije pri pridobivanju in proizvodnji goriv, ne vključuje pa lastne porabe goriv in energije v elektrarnah in toplarnah. V energetski sektor so zajeta podjetja, ki po Standardni klasifikaciji dejavnosti (SKD 2008) spadajo v naslednja področja dejavnosti: Oskrba z električno energijo, plinom in paro (D); Rudarstvo (B), oddelka Pridobivanje premoga (05) in Pridobivanje surove nafte in zemeljskega plina (06); Predelovalne dejavnosti (C), oddelek Proizvodnja koksa in naftnih derivatov (). GCV (gross calorific value) - zgorevalna toplota ali zgornja kalorična vrednost. To je vsa pri zgorevanju sproščena toplota. Proizvajalci po glavni dejavnosti so podjetja, katerih osnovna dejavnost je proizvodnja električne energije, električne energije in toplote ali samo toplote. Lahko so v zasebni ali javni lasti.

Household Consumption Survey (APEGG) is a sample survey in which private households are included. Definitions and explanations Net power is power with which a power plant can operate for a longer time. Share of electricity from renewable sources in total electricity production is the ratio of electricity produced from renewable sources and total electricity production. Share of electricity from renewable sources in gross consumption of electricity is the ratio between electricity produced form renewable sources and gross consumption of electricity. Gross consumption of electricity is electricity generation plus import minus export of electricity. Indicator is defined in Directive 2001/77/EC on the promotion of electricity produced from renewable energy sources in the internal electricity market. intensity is the ratio of energy quantity (total primary energy supply or total final consumption) and gross domestic product at constant prices. intensity decreases with energy efficiency improvements. dependency is the ratio of net imports (import export) and total primary energy supply. It measures the extent to which the country relies on imports to meet its energy needs. use is total consumption of electricity and fuels for drive, internal transport, heating of workplaces and offices, consumption of warm water and steam for drive and technological processes. efficiency is the ratio of total final consumption and total primary energy supply. sector includes fuel and energy that is consumed by the energy industry to support the extraction and production of fuels and transformation activities. It excludes own use of plants. According to the Standard Classification of Activities (SKD 2008), the energy sector covers section Electricity, gas, steam and air conditioning supply (D), from section Mining and quarrying (B) divisions Mininig of coal and lignite (05) and Extraction of crude petroleum and natural gas (06), and from section Manufacturing (C) division Manufacture of coke and refined petroleum products (). GCV (gross calorific value) measures the total amount of heat produced by fuel combustion. Main activity producers are supply undertakings which generate electricity, electricity and heat or heat only as their primary activity. They may be privately or publicly owned. NCV (net calorific value) measures the amount of heat we can use. The other part is used for evaporation of fuel moisture. Renewables comprise solid biomass, biogas, and industrial and municipal waste. Total primary energy supply is the quantity of energy consumed within the borders of a country. It is calculated: indigenous production + imports - exports - international marine bunkers + stock changes. Consumers for households electricity Consumer groups from DA to DE are defined by annual consumption. DA DB DC DD DE <1.000 kwh < kwh < kwh < kwh >= kwh 3

5 Sprememba zalog je razlika med zalogami na začetku in zalogami na koncu obdobja. Statistične razlike vključujejo vsoto nepojasnjenih statističnih razlik za posamezne kategorije goriv, ki lahko nastanejo zaradi uporabe različnih kurilnosti pri preračunu iz naravnih enot v enote za energijo. TE-TO - termoelektrarna-toplarna. To je objekt, ki je namenjen soproizvodnji električne energije in toplote. Tona ekvivalentne nafte (toe) je enota, ki izraža količino sproščene toplote pri zgorevanju ene tone nafte. Toe je računska enota, ki se uporablja v glavnem za prikazovanje porabe energije v energetskih bilancah toe = 41,868 TJ Toplarne so podjetja, ki proizvajajo izključno toploto. Transformacija vključuje porabo goriv za proizvodnjo električne energije in toplote. UNP - utekočinjen naftni plin (butan ali propan ali mešanica obeh). Vsebnost ogljika v oskrbi z energijo je razmerje med celotno količino emisij CO 2 in oskrbo z energijo na nivoju države. Objavljanje Stock change reflects the difference between opening stock level at the beginning of the period and closing level at the end of period. Statistical difference is a category which includes the sum of unexplained statistical differences for individual fuels. It also includes the statistical differences that arise because of the variety of conversion factors. CHP plants are combined heat and power plants which are designed to produce both heat and electricity. Tonne of oil equivalent (TOE) expresses the amount of heat equivalent to the heat of combustion of one tonne of oil. TOE is an accounting unit which is used for expressing energy use in energy balances toe=41,868 TJ Heat only plants are plants which are designed to produce heat only. Transformation includes fuel consumption for electricity and heat production. LPG (liquefied petroleum gas) is butane, propane or a mixture of both. Carbon intensity is the ratio between total amount of CO 2 emissions and total primary energy supply in the country. Publishing Letno: Prva statistična objava. Annually: First Release.
