Energy Account, Australia methodology

The Australian Bureau of Statistics (ABS) Energy Account, Australia (EAA) is one of the environmental-economic accounts produced by the ABS and is based on the System of Environmental-Economic Accounting (SEEA). The SEEA Central Framework is an international standard that enables linkages between ABS environmental-economic accounts and other parts of the National Accounts produced by the ABS. The SEEA-Energy Manual organises energy related data and is consistent with the SEEA Central Framework. 

This  account uses a ‘bottom-up’ approach to compile the physical supply and use tables using a combination of administrative and survey data to reflect activity at industry and household levels. Monetary use estimates have been derived by applying average unit price data to physical product use estimates. This account is the first to produce monetary use estimates for energy products consumed by households, and the new estimates are provided for main products back to 2010-11.

This release contains physical supply and use tables (which show physical values of energy from both a user and producer perspective), monetary use tables (which show the value of energy products used by industry and by households), energy indicators and energy assets at the national and industry level for Australia.

The EAA is based on the SEEA Central Framework. The SEEA Central Framework is a conceptual framework designed to measure the environment and its relationship with the economy. The SEEA Central Framework was adopted by the United Nations (UN) Statistical Commission as an international statistical standard in 2012. The SEEA Central Framework is currently being reviewed and the updated version is expected to be released in 2028.

The SEEA Central Framework uses a systems approach to organise environmental and economic information, covering, as completely as possible, the stocks and flows that are relevant to the analysis of environmental and economic issues. In using this approach, the SEEA Central Framework applies the accounting concepts, structures, rules and principles of the System of National Accounts (SNA). Environmental-economic accounts ('environmental accounts') deliver important extensions to SNA accounts. In practice, these accounts may include physical and monetary supply and use tables, functional accounts (such as environmental protection expenditure accounts), and asset accounts for natural resources.

The EAA provides a framework for linking physical information to core components of the SNA. The production of physical supply and use tables and energy asset tables are (to the extent that it is conceptually possible) consistent with the approaches used in the construction of the SNA. This allows for consistent analysis of the contribution of energy to the economy, the impact of the economy on non-renewable energy reserves, and the efficiency of the use of energy resources within the economy.

The supply tables show the total supply of energy, including energy imports, within the economy. The use tables show the total use of energy, including energy exports. The supply and use tables can be compiled in both physical terms (i.e. Joules) and monetary terms (i.e. dollars).

The supply-and-use concept is based on the fundamental economic identity that the supply of products must equal the use of products, where those estimates are available. The EAA provides information on physical supply and physical use, and these are balanced. However, only monetary use estimates are available in the EAA, and care must be taken when comparing with monetary supply of energy published in other outputs.

Energy indicators are used to provide a greater understanding of the production and use of energy.

Information contained in the EAA combined with additional demographic and economic information provides insights into energy efficiency and energy productivity. Indicators used in the EAA can be divided into three types: total economy indicators; industry indicators and household indicators.

The degree of self-sufficiency (or dependence on imports) measures the proportion of domestically produced energy compared to net energy use plus losses (equivalent to net domestic use plus exports). A self-sufficiency rating of over 100 indicates a net exporter of energy products.

One of the means of extending the life of energy products is to use those products that can be renewed through natural processes. The indicator share of renewable energy in net energy inputs measures the renewable content of non-renewable and renewable net energy supply. The indicator is calculated by dividing the net renewable energy supply by net energy supply.

Energy intensity is a ratio of energy consumed per unit of economic output. The energy intensity analysis is based on the ratios of physical net energy consumption (in gigajoules (GJ)) to industry gross value added (GVA) data.

The EAA uses annually reweighted chain volume estimates of GVA in the estimation of energy intensity from the Australian System of National Accounts (ASNA). These GVA estimates are re-weighted each year, and therefore energy intensity measures are updated with each annual estimation cycle. For example, all figures contained in the EAA 2024-25 estimates of energy intensity are recorded in 2024-25 prices and are thus directly comparable over time.

Household physical energy use is presented on both a per person and per household basis. 

ABS sources for household and population data are:

Both physical and monetary values for energy stocks are published for selected products.

The Net Present Value (NPV) of the resource stocks has been obtained from the Australian System of National Accounts. The NPV is the expected value of the resource based on current resource prices, current extraction methods and costs, and on present physical rates of extraction.

Economically demonstrated energy resources (EDR) consist of known deposits of coal, oil, gas or other fuels and metallic ores, and non-metallic minerals, etc., that are economically exploitable given current technology and relative commodity prices. The extraction rate measures the rate at which assets are being depleted and the remaining resource life measures life of a resource at current production rates.

The EDR/extraction rate ratio provides an indicator of years of availability of a resource.

Australian and New Zealand Standard Industrial Classification, a system used to classify businesses and other organisations by their main activity. It is a standard developed by the Australian Bureau of Statistics and Statistics New Zealand for collecting and analysing industry statistics in both countries.

Average unit prices are mostly derived from the ABS Energy and Water survey (EWS) which collect information on expenditure and use of energy products from Australian businesses. Where not available from EWS, average prices are imputed using price deflators or other price indexes. Expense items are reported exclusive of Goods and Services Tax (GST) where this is recoverable as an input tax credit.

For certain types of economic analysis, it is useful to examine estimates of the principal flows of goods and services in the economy revalued in such a way as to remove the direct effects of price change over the relevant period. These estimates are obtained by weighting together the elemental volume indexes from the previous financial year to the current financial year, where the weights are calculated using the current price value shares of the previous financial year. The resulting aggregate year-to-year volume indexes are linked together to form a time series which is referenced to the current price estimates of the reference year.

Measures the dependence on energy imports to sustain current energy activity. The degree of dependence on imports or 'self-sufficiency', the relationship between gross domestic energy inputs and the domestic end use inclusive of conversion and distribution losses, can be calculated from the Energy Account Australia. This measure is closely connected with the pattern of extraction of energy resources presented in the energy asset tables. An energy self-sufficiency number greater than 100 indicates net exports of energy while a number less than 100 indicates net imports.

The flow of electrical power or charge. It is a secondary energy source, meaning it is derived from the conversion of primary sources of energy such as coal, natural gas, oil, nuclear power, and renewables.

The use of energy products to produce goods and services that are not energy products. It includes energy products that are used by businesses and households as energy end use, exports and additions to stocks.

The term decoupling refers to a break in the link between the use of energy products and economic growth. The extent to which such decoupling takes place can be illustrated by comparing the change in chain volume Gross Domestic Product (GDP) with the change in total domestic use of energy. Decoupling occurs when the growth rate of energy use is less than, or higher than, that of its economic driving force (e.g. GDP) over a given period. Decoupling can be either absolute or relative. Absolute decoupling occurs when the environmentally relevant variable (e.g. energy) is stable or decreasing while the economic driving force is growing. Decoupling is said to be relative when the growth rate of the environmentally relevant variable is positive, but less than the growth rate of the economic variable.

Hydrogen is a lightweight gas found in water and hydrocarbons. It is not freely available in its pure form but is transformed using other energy sources. In the past, hydrogen has been made from fossil fuels such as natural gas and coal but can also be generated from water using renewable electricity and an electrolyser. Hydrogen can be burnt directly, like natural gas. It can also be stored as a gas or liquid and used in fuel cells to generate electricity for remote communities or mining sites, and to power fuel cell vehicles including cars, trucks, buses and trains.

Measures the expected life of a resource under current production levels. Remaining resource life is calculated from the economic demonstrated resource of an energy asset divided by the production rate. This is different to the Net Present Value (NPV) which predicts the expected value of the resource based on current prices, current extraction methods and costs, and on present physical rates of extraction.

Renewable energy is defined as those energy resources that are naturally replenishing. They are virtually inexhaustible in duration but may be limited in the amount of energy available at a given time. Renewable energy resources include biomass, hydro, geothermal, solar, wind, ocean thermal, wave action, and tidal action.

Measures the contribution to total net energy supply through renewable sources extracted by households. The indicator is calculated by dividing household renewable energy supply by total net domestic use.

Measures the proportion of total renewable energy supply compared to total domestic end use. A separate proportion of total renewable energy supply compared to total domestic end use of electricity is also provided.

Energy residuals include flows of energy that are discarded, discharged or emitted by businesses and households. Examples of energy losses include flaring and venting of natural gas and losses during transformation in the production of primary energy products from natural inputs and in the production of secondary energy products. Energy losses during distribution may arise from the evaporation and leakages of liquid fuels, loss of heat during transport of steam, and losses during gas distribution, electricity transmission and pipeline transport. Energy residuals also include dissipative heat losses to the environment resulting from end use of energy products by households and businesses. The EAA provides data on residuals produced during transformation processes and on other residuals from end use of energy products.
