Introduction

The transition to net zero is a broad reaching global challenge, impacting the economy, society and environment. In Australia a range of policies have been introduced to help us progress towards net zero goals and support transition planning. 

Wide ranging data is needed to support this transition requiring analysis across many themes. The ABS environmental economic accounts program provides data opportunities. This article explores some of the ABS energy related data that can support information needs for Australia’s Net Zero transition.

What is Net Zero?

The Australian government defines Net Zero as the broad policy plan to reduce emissions to a net result of zero by 2050 (Net Zero - DCCEEW). Net zero will be achieved when the level of greenhouse gas emissions removed from the atmosphere offset those produced by human activities. 

A net zero plan has been established by the Australian Government setting out emission reduction targets and establishing sector specific plans to support investment in low emissions and renewable technologies. Legislative instruments exist to guide businesses towards net zero as well as targeted subsidies to encourage investment.

Measuring Net Zero

Net zero data requirements include greenhouse gas emissions, energy production and consumption, infrastructure investment, and household and business transition impacts, including prices. 

Net zero macro-economic analysis is best served when both physical and monetary measures of the environment are on a consistent basis. The System of Environmental Economic Accounts (SEEA) (System of Environmental Economic Accounting |) is the international standard that brings both dimensions together. The SEEA uses the same concepts and classifications as the System of National Accounts (SNA), enabling the linkages with macro-economic accounts. In Australia, the SNA and SEEA guide the collection of key economic and environmental data.

Energy Accounts capture the supply and use of energy products. Energy Accounts Australia tracks the allocation of physical energy as it passes through the economy and is distributed to other businesses, households and exports. An advantage of this format is that it is consistent with the laws of thermodynamics where all energy and heat are accounted for and can thus be related to macroeconomic transactions. Energy Account Australia includes supply and use tables for all sources of energy as well as asset accounts for non-renewables.

The remainder of this article uses recent ABS data to show 9 energy related presentations that help narrate the net zero story.

The Net Zero Story

Infographic showing 9 energy insights related to Australia's net zero transition

An infographic showing 9 energy data insights to help narrate Australia’s net zero transition using ABS data. Insights are in sequential order and include; energy exports exceed domestic energy use, energy use starting to decouple from economic growth, businesses becoming more energy efficient, the increasing share of renewable electricity, investment in non-renewables and transmission exceeding investment in renewables infrastructure, increased energy prices, energy’s mixed impact on productivity, energy industries contribute nearly $235 billion to the economy, and coal and natural gas dominate energy exports. 

Energy use

Energy exports exceed domestic energy use

The energy accounts balance the supply and use of energy. This is meaningful when considered in the three stages of energy consumption: natural inputs, transformation into energy products, and energy end uses. For example, the amount of energy supplied by the environment matches the energy extracted (used) by industry for natural inputs. 

From the ABS energy accounts we can see that in 2022-23, natural inputs from non-renewable sources (20,475 petajoules (PJ)) exceeded renewable sources (522 PJ);  and energy exports (17,434 PJ) exceeded  industry end use (3,140 PJ), energy consumed in transformation processes (1,484 PJ), and household use (1,009 PJ). Energy from renewable sources was 2.5% of outputs from the environment in 2022-23.

Energy decoupling

Energy use is starting to decouple from economic growth

A key strategy in the net zero transition is continuing to grow the economy while reducing the economy’s reliance on energy as an input to that growth. Using 2010-11 as the base year, Australia’s real GDP growth was 31% through to 2022-23, while net energy use grew by 19%. The energy growth was driven by trade in fossil fuels, with extraction capability growing between 2010-11 and 2018-19. Post COVID-19, energy use has begun to exhibit some relative decoupling from economic growth.

Energy intensity

Businesses are becoming more energy efficient

Energy intensity reflects the amount of energy used to produce output. Energy intensity across the Australian economy decreased by over 17% between 2010-11 and 2022-23, led by commercial services (-29%), manufacturing (-16%), electricity, gas, water and waste industry (-8%) and transport (-1%). These were offset by mining (+14%) and construction (+6%), as these industries increased their energy intensity over the timeseries.

Energy mix

Share of renewable electricity is increasing

Electricity is a key factor of production for Australian economic growth. Electricity accounted for 24% of net energy end use (or what drives the non-energy generation part of the economy) in 2022-23, second only behind diesel and petrol use (44%). While electricity demand has continued to grow in line with population growth, renewables started accelerating from 2010-11 and are increasingly replacing non-renewables.

Electricity infrastructure investment

Investment in non-renewables and transmission exceeds investment in renewables

Investment in renewables is accelerating, however the investment in other electricity i.e. non-renewable generation, transmission wires and poles,  remains higher. The value of work completed for renewables ($1.6 billion for June 2022), quarter on quarter, was still lower than non-renewables and transmission ($2.7 billion for June 2022).

Note: Renewables include generation and storage investment based on hydro-electric generating plants, wind farms, utility scale solar farms and pumped hydro generation as well as battery storage. Rooftop photovoltaic systems are out of scope of the Engineering Construction Survey though they are recognised as a notable contributor to renewable energy. Other electricity investment includes generation, transmission and distribution data so the information presented is broader than just new generation projects. Other electricity assets include non-generation investment such as maintaining and expanding existing transmission networks, connecting new renewable projects to existing networks and non-renewable generation assets ie. coal and gas power plants. 

The cumulative value of new energy investment highlights this difference, with $51 billion of infrastructure for wires and poles between March quarter 2016 and June quarter 2022, outpacing renewables ($26 billion). Over the same time period, the change in non-renewable electricity generation decreased by 14% (-108 PJ), while renewable electricity generation doubled (up 108% to 157 PJ).

Energy prices

Energy prices have increased

Energy prices respond to pressures from supply, infrastructure, global events and other costs. Using June quarter 2012 as the baseline price for a household electricity package, the price of electricity increased 53 points by June quarter 2024. Over the same period the CPI grew by 38.2 points.

For industry, the input costs of electricity increased by 41.9 points from a 2012 baseline. Gross operating surplus (related to gross company profits) and gross mixed income (profits of small and non-employing businesses) increased by 77% over the same time period.

The transition away from non-renewables is not just about electricity. Other energy sources such as petrol and diesel play a large role in domestic consumption and mining products are a major component of Australia’s trade with other countries. The prices of all inputs to the Manufacturing industry grew by 28.7 points between June 2004 and June 2014, then by 45 points between June 2014 and June 2024. 

Between June 2004 and June 2014, coal mining price inputs into manufacturing increased by 40.4 points and natural gas input prices by 55.1 points. Between June 2014 and June 2024 these increased further to 66.9 points for coal mining and 69.0 points for natural gas inputs.

Energy impact on productivity

Energy impact on productivity mixed

The KLEMS framework provides a detailed statistical decomposition on the contributions to output growth, represented by five input categories - capital (K), labour (L), energy (E), materials (M), and services (S). This enables analysis on input mix changes, such as the role energy intermediate inputs, observed in industry output growth. Other things being equal, lower cost share means higher energy efficiency

Energy contribution in productivity can demonstrate if there is an increase in consumption to drive growth. For example, in 2019-20 the contribution to growth from energy decreased, reducing growth by 1.6 points. Transport, postal and warehousing energy inputs contributed an increase to growth of 0.6 in 2021-22, following a reduction in activity during COVID 19.

The cost of energy as a factor of growth can also be used to understand the impact of efficiency and innovation in industry groups. Other things being equal, lower cost shares mean higher energy efficiency. Between 2019-20 and 2021-22, Transport, postal and warehousing had the highest cost share of energy (declining between 8.5% to 7%) and the most variable contribution to growth from energy, while the Manufacturing cost of energy declined from 6.5% to 5.5%.

Energy industries contribution to national income

Energy industries contribute nearly $235 billion to the economy

Income generated from the economy can be split according to its distribution, into compensation of employees, gross operating surplus, and net taxes paid to government. These are close representations of gross national income (GNI) by industry. These indicators represent the contribution of income from energy businesses as a share of national income. 

The contribution to GNI by energy industries peaked at nearly 10% in 2022-23. This was largely driven by coal mining (4% of GNI or $103b) and oil and gas extraction (4% of GNI or $100b). Over the past 12 years, the contribution of electricity generation and supply diminished to 1% of GNI ($24b).

Some of this income was distributed to households in the form of compensation of employees (including employee wages, salaries and supplements). The compensation of workers in the electricity generation and supply industry was $8.3b in 2022-23, while in coal mining it was $8.2b.

Energy trade

Coal and natural gas dominate energy exports

The value of energy net exports has increased substantially over the past 20 years. Exports of energy products was $179 billion in 2023-24, up from $20.5 billion in 2003-04. Imports rose at a more moderate pace, growing from $10.1 billion in 2003-04 to $62.1 billion in 2023-24. Fossil fuel exports of coal and natural gas accounted for 89% of Australia’s energy exports in 2023-24. Imports of energy were mainly crude oil, petrol and diesel (97%) in 2023-24.

In aggregate, Australian production of energy exceeded domestic energy needs by close to 370% in 2022-23.

Future extensions

Energy related data are also available in other ABS datasets, and the ABS’ coverage of net zero could potentially be expanded in future releases to cover other characteristics. 

In relation to net zero, it is worth noting emissions reporting. The SEEA manual includes energy and air emissions accounting. ABS has compiled Energy Accounts since 1996 but currently does not produce SEEA-based Air Emissions Accounts. The current Australian National Greenhouse Gas Accounts (Home | ANGA (climatechange.gov.au)) are the Australian version of the UN Framework Convention on Climate Change (UNFCCC) reporting. While the UNFCCC reporting framework is used to report Australia’s emissions inventories internationally, it is not fully comparable with the SEEA / SNA. This is because the SEEA / SNA capture activity based on residency, while the UNFCCC uses the territory concept. Further adjustments are required to link the UNFCCC emissions data with economic data.
