5 Foreword Australia s economy and prosperity are built on access to secure, affordable and reliable energy. Our energy diversity is one of Australia s natural strengths and one of our best competitive advantages. This diversity provides Australian homes and business access to the energy needed to build our industries and our communities. Our coal, gas and uranium exports supply global markets hungry for energy security. The depth of the Australian energy resource base will support continued energy production well into the future. The energy sector plays a vital role in the Australian economy, accounting for 7 per cent of GDP and $71.5 billion in export earnings in Australia is the among the world s largest exporters of LNG, coal and uranium, and our importance to global energy markets will continue to grow. Energy related industries also contributed 1.5 per cent to total Australian employment in , and provided significant infrastructure investments. The Australian energy market has undergone significant transformation in recent years as a result of declining demand and changing patterns of consumption. It is essential that we have a long-term framework in which the energy sector can grow, and adapt to the transformations taking place in Australian and global energy markets. In September, the Australian Government released the Energy Green Paper, ahead of the preparation of the Energy White Paper which will be a comprehensive blueprint for Australia s energy future. i

6 The Green Paper is built around four key themes attracting energy resources investment, electricity prices, building gas supply and improving market operation and security, and innovation and energy productivity. Getting our policy settings right will facilitate further growth and enhance productivity. To visualise and plan for where we are going, it is vital to know where we are now. Energy in Australia 2014 provides facts and figures on Australia s energy sector, covering all areas of energy production and use, from natural resources through to final consumption. Now in its tenth year, Energy in Australia 2014 is an essential source of information for policy makers and industry alike in understanding Australia s energy markets, how we supply and use energy in Australia, and informing policy development and investment in the energy sector. The production of objective economic advice, analysis and statistics for the resources and energy sectors is a high priority for the Australian Government. From 1 December, the activities of the Bureau of Resources and Energy Economics will come under the Office of the Chief Economist in the Department of Industry. This will consolidate the Department s extensive economic expertise in one place, and ensure that timely, accurate and objective information on Australia s resources and energy sectors continues to be available to all.

13 Energy resources Australia has extensive and diverse energy resources, including both renewable and non-renewable energy. Fossil fuel resources include black and brown coal, and conventional and unconventional gas and oil. Australia also has the world s largest uranium resources. Renewable energy resources include wind, solar, hydro, bioenergy, geothermal, wave and tidal. These resources are widely distributed around the country and with the exception of oil, are expected to last for many more decades, even with increasing production. 1 Energy production Australia produces energy for its own use and for export overseas. Primary energy production in Australia was petajoules in Net exports (exports minus imports) were equivalent to 68 per cent of energy production in that year. Australia is the world s eighth largest energy producer, accounting for 2.4 per cent of world energy production in Coal accounted for 59 per cent of Australia s energy production on an energy content basis in , followed by uranium (22 per cent). Natural gas accounted for 13 per cent of energy production, oil a further 5 per cent, while renewable energy mostly bioenergy and hydro contributed 2 per cent. Energy production rose by 9 per cent in , supported by increased black coal, uranium and natural gas production for export markets. Over the past ten years, energy production has grown by 2 per cent a year on average. Queensland and New South Wales are the largest energy producing states, with most of Australia s black coal production. 1

Economic contribution The energy industry is an important part of the Australian economy. In it contributed nearly $106 billion to industry gross value added, around 7 per cent of Australia s gross domestic product. The coal mining and oil and gas extraction industries are the largest, contributing $64 billion to industry gross value added in The electricity supply industry contributed a further $22 billion. Energy related industries also contributed 1.5 per cent to total Australian employment in , and provided significant infrastructure investments. 3

16 Energy consumption Australia s energy consumption has been growing slowly over the past ten years, at an average annual rate of 1.1 per cent. In , primary energy consumption declined by 0.5 per cent, to 5884 petajoules, mainly due to a decline in energy use in the electricity generation sector. The electricity generation, manufacturing and transport sectors are the largest energy consumers in Australia, accounting for around three-quarters of energy consumption in Oil is the largest source of energy in Australia, accounting for 38 per cent of primary energy consumption in Coal accounted for a further 33 per cent of energy consumption in , its lowest share since the early 1970s. Natural gas and renewable energy accounted for 24 per cent and 6 per cent respectively. Of the 6 per cent renewables, the majority was provided by bioenergy and hydro.

18 Energy trade Australia s net energy exports (exports minus imports) in were equivalent to 68 per cent of production. Energy exports accounted for 31 per cent of the value of Australia s total commodity exports in , and were valued at $71.5 billion. Coal was the largest energy export earner, with a value of around $40 billion in , followed by LNG ($16.4 billion) and crude oil ($11.1 billion). Earnings from energy exports fell by 12 per cent in , largely as a result of lower coal prices. Earnings rose by 6 per cent in , supported by higher LNG prices. Australia s real energy export earnings have increased by 8 per cent a year on average over the past ten years.

19 Box 1: Energy flows through the Australian economy 1 Australia produces energy directly from natural resources, such as coal, crude oil, natural gas and wood, referred to as primary energy. This primary energy can be exported, or used domestically. Domestically, primary energy is generally transformed in power plants and refineries into other types of energy such as electricity, petrol and diesel (derived fuels), for use by Australian industries and households. Industries and households can also use primary energy sources such as natural gas and wood directly. Australia imports both primary energy such as crude oil, and derived energy products such as diesel and petrol. Energy consumption is a net concept. To avoid double counting, derived fuels that are produced domestically are subtracted from primary fuels, as the energy embodied in these fuels is already accounted for in the primary fuels that they are produced from. Figure 1.5 shows the flow of energy through the Australian economy. In Australia produced 2439 petajoules of natural gas, and imported a further 244 petajoules of gas from the Joint Petroleum Development Area in the Timor Sea. Of this combined total, 1303 petajoules were exported as liquefied natural gas, 588 petajoules were transformed into other energy types such as electricity, and 799 petajoules were used directly by industries and households (plus a statistical discrepancy of 6 petajoules). 7

22 Australia s energy imports were valued at $40.8 billion in Crude oil and refined petroleum products were the predominant energy imports, which were valued at $20.4 billion and $17.9 billion respectively. Australia is a net importer of crude oil and refined petroleum products, with net imports accounting for 35 per cent of oil consumption in , compared with 7 per cent a decade ago.

24 Overview Energy can be extracted or captured directly from natural resources, including coal, crude oil, natural gas, wood, wind and solar energy, or by transforming these sources into other types of energy, such as burning coal to make electricity and refining crude oil to make petrol and diesel. Australia has abundant and diverse natural resources, including non-renewable and renewable resources. These high quality energy resources are widely distributed across the country and supply energy for domestic consumption and the world market. Australia holds the world s largest economic uranium resources, the fourth largest black and brown coal resources, and substantial conventional and unconventional gas resources. This globally significant resource base is capable of meeting domestic and export demand for many more decades. There remain significant underexplored and unquantified resources both onshore and offshore, with the potential for future resource discovery and development. Identified resources of crude oil, condensate and liquefied petroleum gas are more limited, and Australia is increasingly reliant on oil imports. Australia has significant renewable energy resources, with utilisation growing strongly over the past decade. Australia has some of the highest solar radiation levels per square kilometre of any continent in the world. Wind, geothermal, wave and tidal energy resources are also world class and hold considerable potential. 12

28 Coal Australia holds around 9 per cent of the world s proven reserves of black coal and 22 per cent of the world s proven reserves of brown coal. Australia s total coal reserves rank fourth behind the United States (27 per cent), Russia (18 per cent) and China (13 per cent). At the end of 2013, Australia s recoverable Economic Demonstrated Resources (EDR) of black coal were estimated at petajoules (62.1 Gt). It is estimated that there are a further petajoules (5.1 Gt) of Sub-economic Demonstrated Resources (SDR) of black coal. Brown coal EDR were estimated at petajoules (44.2 Gt) at end of At current production rates, Australia s black coal EDR will support a further 110 years of production. Accessible brown coal EDR will support a further 510 years of production. Coal deposits are generally located in the east of Australia close to areas of domestic energy demand. Most of Australia s recoverable black coal EDR is located in Queensland (61 per cent) and New South Wales (36 per cent), in the Bowen, Surat and Sydney basins. The majority of Australia s brown coal resources are in Victoria s Gippsland Basin. Oil Australia has limited resources of crude oil, and most known remaining oil resources are condensate and naturally occurring liquefied petroleum gas (LPG) associated with large offshore gas fields. Australia holds around 0.2 per cent of world crude oil reserves. At the end of 2012, Australia s EDR of oil were estimated at petajoules (3753 Mbbl), comprising petajoules (1938 Mbbl) of condensate, 5038 petajoules (856 Mbbl) of crude oil and 4118 petajoules (959 Mbbl) of LPG. Australia s ratio of EDR to current production is estimated at around 16 years for LPG, 7 to 10 years 16

29 for crude oil and 25 years for condensate. The ratio for oil has remained around this level since the 1980s due to new discoveries and existing resources becoming more economic. Approximately 94 per cent of Australia s oil resources are located in four basins. These are the Carnarvon, Browse and Bonaparte Basins off the north-west coast of Western Australia and the Northern Territory, and the Gippsland Basin off the south-east coast of Victoria. 2 Gas Australia holds approximately 2 per cent of world EDR of conventional gas. At the end of 2012, Australia s EDR of conventional gas were estimated at petajoules (2.83 tcm). At current production rates, there are sufficient EDR of conventional gas to last another 51 years. Australia also has significant unconventional gas resources. Coal seam gas (CSG) EDR has doubled in the past three years to an estimated petajoules (1.16 tcm) at the end of This is equivalent to more than one-third of Australia s conventional EDR. Total identified resources of CSG are estimated to be petajoules (5.75 tcm). Australia may also have significant resources of shale and tight gas, although estimates of potential resources have a high degree of uncertainty. Most (around 92 per cent) of Australia s conventional gas resources are located in the Carnarvon, Browse and Bonaparte basins off the north-west coast. There are also resources in south-west, southeast and central Australia. Large CSG resources exist in the coal basins of Queensland and New South Wales. Most potential shale gas resources are in South Australia. 17

30 Uranium Australia has the world s largest EDR of uranium with an estimated petajoules (1167 kt) at the end of This represents around one-third of global resources. At current rates of production, Australia s uranium resources are sufficient for a further 170 years of production. The majority of Australia s uranium resources are located in South Australia, the Northern Territory and Western Australia. The Olympic Dam deposit in South Australia is the world s largest uranium deposit. Australia has significant potential for the discovery of new uranium resources, including through the newly released Woomera Protected Area in South Australia. Exploration Exploration expenditure on energy resources in Australia was $5.3 billion in , one of the highest levels of spending on record. Oil and gas accounted for 92 per cent of total expenditure in , at around $4.9 billion. Oil and gas spending rose by 46 per cent in , reflecting historically high oil prices and the large number of projects under development. This level of spending was maintained in In contrast, coal and uranium exploration spending has dropped significantly in the past two years, as Australia continues to transition from the investment to production phase of the mining boom. Slowed expenditure can also be attributed to softening coal and uranium prices and risk mitigation as companies look to confirm brownfield reserves instead of expanding into higher risk greenfield exploration activities. 18

Renewables Australia has a rich diversity of renewable energy resources, including wind, solar, geothermal, hydro, wave, tidal and bioenergy. Uptake of renewable energy is growing and there is significant potential for further development. Renewable energy resources are generally transient and not always available, and are therefore not readily classifiable and comparable to non-renewable resources. Australia s wind resources are some of the best in the world, primarily in the south-western, southern and south eastern margins and extending hundreds of kilometres inland. These resources are making an increasing contribution to Australia s electricity generation. High solar radiation levels over much of Australia provide some of the best solar resources in the world, and developments in commercial scale solar technologies are expected to encourage further utilisation. The annual solar radiation falling on Australia is approximately petajoules, nearly ten thousand times larger than Australia s current annual energy consumption. 19

32 Map 2.2: Australia s solar energy potential Source: Geoscience Australia and BREE 2014, Australian Energy Resource Assessment. Australia has significant geothermal resources, potentially suitable for electricity generation and direct use. Identified geothermal resources as of December 2012 are estimated at around petajoules. However, some of the more prospective geothermal resources in central Australia are long distances from infrastructure and centres of demand, and potentially costly to develop. There is presently no commercial scale production of geothermal electricity in Australia. 20

33 Map 2.3: Australia s geothermal energy potential 2 Source: Geoscience Australia and BREE 2014, Australian Energy Resource Assessment. Australia has world class wave energy potential, particularly along the south-western and southern coasts. Australia also has potential tidal energy resources off the northwest coast of Western Australia. Wave and tidal energy projects are still at the development/pilot stage. Hydro has limited potential for further development, with any future growth being determined by water availability. Australia s technically feasible hydro energy potential is estimated to be around 216 petajoules a year. 21

34 Map 2.4: Australia s wind energy potential Source: Geoscience Australia and BREE 2014, Australian Energy Resource Assessment. Potential bioenergy resources in Australia are large and diverse. Bioenergy is derived from biomass (organic materials) to generate electricity and heat, and to produce liquid fuels for transport. Potential resources include wood, wood waste, bagasse, gas from landfill and sewage, crops and animal fats. Commercialisation of advanced bioenergy technologies is likely to increase the range of resources, such as non-edible parts of plants and algae. 22

36 Overview Australia consumed 5884 petajoules of energy in , with 94 per cent coming from fossil fuel sources (coal, oil and gas). Australia was the world s nineteenth largest energy consumer in 2012, and ranked sixteenth on a per person basis. While Australia s long-term economic growth has been relatively stable over recent decades, growth in energy consumption has gradually slowed over the same period. Before the 1990s, Australia s growth in energy consumption largely mirrored economic growth. Following average annual growth of around 5 per cent during the 1960s, growth in energy consumption fell during the 1970s to around 4 per cent a year, largely as a result of the two oil price shocks. During the 1980s, economic recession and rising energy prices resulted in annual growth falling to around 2.5 per cent. In the 1990s annual growth in energy consumption remained around 2.6 per cent, and around 1.7 per cent in the 2000s. Since , Australia s energy consumption has been relatively flat, with a fall in energy use in electricity generation offsetting growth in end use sectors such as manufacturing, transport and mining. 24

37 Figure 3.1: Annual growth in Australia s energy consumption = GDP Source: BREE 2014, Australian energy statistics, Table B. Energy consumption Energy intensity Since the 1990s, there has been a steady decline in energy intensity (the ratio of energy use to activity in the Australian economy). This can be attributed mainly to improvements in energy efficiency associated with technological advancement, and a shift in industry structure towards less energy-intensive sectors such as commercial and services. In , energy intensity, as defined by the ratio of energy consumption to gross domestic product, declined by 3 per cent. Trends in energy intensity are not uniform across states and territories. Western Australia and Queensland have higher energy intensities than other states, mainly due to the mining and energy intensive manufacturing industries accounting for a higher proportion of their economies and energy consumption. Tasmania has a lower energy intensity, with less energy-intensive industry sectors than in other states. 25

38 Figure 3.2: Energy intensity trends, by state = Aus Vic WA NSW SA QLD Tas Source: BREE 2014, Australian Energy Statistics, Table B. By energy type Fossil fuels including coal, oil and gas dominate Australia s primary energy consumption. Oil is Australia s largest source of energy, accounting for 38 per cent of consumption in Increased use of oil in the mining and transport sectors contributed to growth of 1 per cent in oil consumption in Coal is the second largest primary fuel consumed in Australia, but its share of total energy consumption is falling. In black and brown coal accounted for 33 per cent of energy consumption, the lowest share since the early 1970s. Coal consumption fell by 6 per cent in , underpinned by falling coal use in the electricity generation and iron and steel sectors. 26

39 The share of natural gas in Australia s energy mix has increased in recent years, supported by greater uptake in the electricity generation sector and growth in industrial use, particularly in the non-ferrous metals sector. In , natural gas accounted for 24 per cent of energy consumption. Gas consumption rose by 2 per cent in , supported by an expansion in alumina output and additional gas-fired electricity generation capacity. Renewable energy sources accounted for the remaining 6 per cent of Australia s energy consumption in Renewable energy consumption rose by 12 per cent in , with growth in all renewable energy sources except for biogas and biofuels. 3 Figure 3.3: Australia s primary energy consumption, by energy type PJ Coal Oil Gas Renewables Source: BREE 2014, Australian Energy Statistics, Table C. 27

42 By industry Australian energy consumption fell marginally in Growth in energy consumption in the mining, manufacturing and commercial and services sectors was offset by a fall in energy use for electricity generation. Final energy consumption (energy consumed by end-use sectors excluding energy used in energy transformation/conversion activities such as electricity generation) rose by 2 per cent in The electricity, transport and manufacturing sectors were the largest energy users in Together these sectors accounted for around three-quarters of Australia s energy consumption. The electricity sector accounted for the largest share, 28 per cent in In , energy consumption in this sector (including fuel inputs to electricity generation and own use) declined by 6 per cent, mainly due to reduced electricity demand. The transport sector was the second largest energy consumer, accounting for 26 per cent of the total. In , increased energy use in road, rail and air transport resulted in a marginal increase in energy consumption in the transport sector. New South Wales and Victoria, the largest two energy consuming states, together account for around half of energy consumption in Australia. In all states and territories except Tasmania and North Territory, electricity, transport, and manufacturing are the largest energy using sectors. The electricity sector has the highest share in Victoria, accounting for 36 per cent of state energy consumption in ; while transport has the highest share in New South Wales. The mining sector is among the largest energy users in the Northern Territory and Western Australia. 30

47 Energy efficiency Australia is becoming more energy efficient as a result of new technologies, policies and regulations, and changes in consumer behaviour. Over the last two decades there has been a significant coordinated effort between Australian and state and territory governments to ensure that energy efficiency opportunities are recognised and realised. In 2009, Australian governments entered into a national partnership agreement and developed a National Strategy on Energy Efficiency to accelerate energy efficiency efforts. Energy efficiency improvements are occurring in large industrial energy users, in buildings, transport, and in household energy use. In particular, improved efficiency of appliances such as refrigeration, air conditioning and electronics, and more stringent energy efficiency requirements in the Building Code, are influencing Australia s energy use trends, along with consumer responses to higher prices. For example, air conditioners today are around one-third more efficient than a decade ago, supported by the introduction of Minimum Energy Performance Standards (MEPS) from The least efficient air conditioner (of 4 kilowatts or less) today is more efficient than the most efficient air conditioner on the market in

Figure 3.8 shows an example of the cumulative effects of these energy efficiency improvements on electricity use in Melbourne homes on a hot day (with a maximum temperature of 35 degrees Celsius) and on a mild day (with a maximum temperature of 23 degrees Celsius). Both total electricity use and peak demand are lower in houses constructed more recently. Minimum performance standards for a range of common household appliances and efficiency requirements in the Australian Building Code are estimated to have saved consumers over $10 billion (net present value) in avoided energy costs between 2000 and

Energy expenditure In 2012, Australian households spent an average of $99 a week on energy. This included $39 a week on energy sources used within the dwelling such as electricity or gas, and $60 a week for fuel for vehicles. Australian households average expenditure on energy represented 5.3 per cent of total gross weekly household income. Low income households spent on average almost 10 per cent of their gross household weekly income on total household energy costs, around three times that of high income households. Spending also varied across states and territories, with total household energy costs higher in the Northern Territory ($110 a week) and the Australian Capital Territory ($109 a week) than in most other states and territories. 37

52 The Australian electricity market Electricity is transported from power stations via electricity transmission networks to electricity distributors and large end users. Electricity distribution networks carry electricity to customers, including households, businesses and industrial users. Electricity retailers buy electricity in wholesale markets, package it with costs associated with provision of network services, and sell it to customers. The Australian electricity market comprises three distinct electricity systems: the National Electricity Market (NEM), the Western Australian market, and the Northern Territory market. Due to the high costs associated with transporting electricity over long distances, Western Australia and the Northern Territory are not connected to the NEM. National Electricity Market (NEM) In the eastern states, the NEM forms a single electrically connected system extending from Port Douglas in Queensland, through New South Wales, the Australian Capital Territory, Victoria and Tasmania to Port Lincoln in South Australia. The NEM is connected by six major transmission interconnectors. Electricity network infrastructure in the NEM comprises around kilometres of transmission lines and kilometres of distribution lines. The Australian Energy Market Operator (AEMO) is responsible for the operation of the NEM. The NEM comprises the physical infrastructure of the electricity network, and the operation of a wholesale market for the supply of electricity to end-users. Exchanges between electricity generators and consumers are facilitated through a gross energy pool. Output from generators is aggregated and scheduled to meet demand. 40

54 Western Australia Western Australia s networks consist of the South-West Interconnected System (SWIS) which includes Perth, and the North-West Interconnected System (NWIS) for the mining areas in the north. While not connected electrically, the SWIS and NWIS are connected through gas pipelines. The SWIS network comprises kilometres of transmission lines, and around kilometres of distribution lines. The SWIS accounts for approximately threequarters of generation in Western Australia. The NWIS network consists of around kilometres of transmission and distribution lines with a service area that covers 2.3 million square kilometres, including the Kimberley, Pilbara, Gascoyne, Mid West and Esperance, Hopetoun and Norseman in the Southern Goldfields. The Wholesale Electricity Market (WEM) in the SWIS comprises an energy market and the Reserve Capacity Mechanism (RCM). There are two types of market participants: market generators are owners or controllers of generation systems; market customers are sellers of electricity to retail customers, large individual consumers or demand side management (DSM) aggregators. Northern Territory The Northern Territory s electricity industry is small and consists of three regulated systems: the Alice Springs regulated system; the Darwin Katherine regulated system; and the Tennant Creek regulated system. There are also many small off-grid systems that primarily support indigenous communities and mining operations. Electricity production Electricity generation in Australia has been declining over the past few years, in response to falling electricity demand. In , Australia s total electricity generation was 249 terawatt hours, a decrease of 1.7 per cent from

56 Coal-fired power stations provide the majority of Australian electricity generation, as coal is a relatively low cost and abundant energy source in Australia. Black and brown coal accounted for 64 per cent of total electricity generation in However, coal use in electricity generation has been declining over the past decade, with its share falling from 77 per cent in In , coal-fired generation declined by 7 per cent. Gas is Australia s second largest source of electricity, accounting for 20 per cent of generation in Gas-fired generation increased by 5 per cent in , supported by new capacity coming on line in Victoria. Renewable energy sources, mainly hydroelectricity, wind and bioenergy, accounted for 13 per cent of electricity generation in , supported by a significant boost to hydro generation.
