, and geothermal) 0.042%. Note that these figures exclude a significant amount of energy saved through use of solar water heating units as they do not actually produce electricity; this is calculated separately to be 7.4% of clean energy production. Biogas had the fastest rate of growth in 2008-09 with around 33%, followed by solar and wind with 6.5%.

In the year to October 2010 Australian electricity production was 251 TWh, with an estimated 21,751 GWh or 8.67% generated from renewables, and 91.33% from fossil fuels (note: this excludes a further approximately 1.6 GWh produced through solar water heating). This compares to 2006 figures, where approximately 9,500 GWh of electricity came from renewable sources, representing less than 4% of electricity consumption for that year.

Australia has the potential for vast renewable energy capabilities. However this is not yet fully realised and the country's abundant resources are currently under utilised. The significant deployment of these technologies would substantially mitigate Australia's greenhouse gas

In 2007–08 hydro-electricity represented 15% of renewable energy production in Australia.

Wind power

As of October 2010, around 22.9% of Australia's renewable electricity, and 2% of Australia's total electricity, was sourced from wind power, enough electricity to power more than 700,000 homes. This came from 52 operating wind farms containing a total of 1,052 turbines producing approximately 5,000 GWh of electricity per year. This figure represented approximately a 30% increase in wind power generation each year over the previous decade, or a total increase of more than 1,000% over that time. The total installed capacity as of October 2010 was 1,880 MW (including only projects over 100 kW), with a further 1,043 MW under construction.

Solar photovoltaics

Solar photovoltaic (PV) technology generates electricity from sunlight, and it can be used in grid-connected and off-grid applications.

The issue for the Australian photovoltaics industry today is that there is enormous market potential, built up through a natural competitiveness in Australian research and development, industry investment and government policy support. However, despite this, the industry is not yet self-sustaining and advantages gained to date could be lost. A 2004 market report suggested that a partnership between government and industry is necessary:

"The PV industry cannot continue to actively invest in strategic industry development unless the Australian government is also committed to the journey. The industry ... requires policy and program support to assist it in bridging the gap to mainstream commercial competitiveness."

Two recent projects which illustrate co-operation between industry and government are the solar power station planned for north-western Victoria, and the development of new solar cells.

Solar thermal energy

Australia has developed world leading solar thermal technologies, but with only very low levels of actual use. Domestic solar water heating is the most common solar thermal technology.
Solar water heating


During the 1950s, Australia’s Commonwealth Scientific and Industrial Research Organisation
Commonwealth Scientific and Industrial Research Organisation
The Commonwealth Scientific and Industrial Research Organisation is the national government body for scientific research in Australia...

 (CSIRO) carried out world leading research into flat plate solar water heaters. A solar water heater manufacturing industry was subsequently established in Australia and a large proportion of the manufactured product was exported. Four of the original companies are still in business and the manufacturing base has now expanded to 24 companies. Despite an excellent solar resource, the penetration of solar water heaters in the Australian domestic market is only about 5%, with new dwellings accounting for most sales.

It is estimated that by installing a solar hot water system, it could reduce a family's CO2 emissions up to 3 tonnes per year while saving up to 80% of the energy costs for water heating.

While solar water heating saves a significant amount of energy, they are generally omitted from measures of renewable energy production as they do not actually produce electricity. Based on the installed base in Australia as of October 2010, it was calculated that solar hot water units would account for about 7.4% of clean energy production if they were included in the overall figures.
Solar thermal power


There are no large large scale solar thermal power stations in Australia, although the country has significant research, development and commercialisation efforts.

Geothermal energy

In Australia, geothermal energy is a natural resource which is not utilised as a form of energy. However there are known and potential locations near the centre of the country in which geothermal activity is detectable. Exploratory geothermal wells have been drilled to test for the presence of high temperature geothermal activity and such high levels were detected. As a result, projects will eventuate in the coming years and more exploration is expected at potential locations.

South Australia has been described as "Australia's hot rock haven" and this emissions free and renewable energy form could provide an estimated 6.8% of Australia's base load power needs by 2030. According to an estimate by the Centre for International Economics, Australia has enough geothermal energy to contribute electricity for 450 years.

There are currently 19 companies Australia-wide spending $A654 million in exploration programmes in 141 areas. In South Australia, which is expected to dominate the sector's growth, 12 companies have already applied for 116 areas and can be expected to invest $A524 million (US$

This is piped onshore to drive a turbine and to create desalinated water. A series of large buoys is tethered to piston pumps anchored in waters 15 to 50 metres deep (49 to 131 feet). The rise and fall of passing waves drives the pumps, generating water pressures of up to 1,000 pounds per square inch (psi). The company is looking to have a 50 MW demonstration project finished within the next four years.

Legislation imposes a 10% cap on the concentration of fuel ethanol blends. Blends of 90% unleaded petrol and 10% fuel ethanol are commonly referred to as E10, which is mainly available through service stations operating under the BP, Caltex, Shell, and United brands.

In partnership with the Queensland Government, the Canegrowers organisation launched a regional billboard campaign in March 2007 to promote the renewable fuels industry. Over 100 million litres of the new BP Unleaded with renewable ethanol has now been sold to Queensland motorists.

Biodiesel produced from oilseed crops or recycled cooking oil may be a better prospect than ethanol, given the nation’s heavy reliance on road transport, and the growing popularity of fuel-efficient diesel cars.

More recently, a third wind farm has reached financial close for Wind Prospect in South Australia. This is the 95 MW Hallett Wind Farm which is expected to be fully commissioned late in 2008.

Subsidies for fossil fuels

Governments in Australia provide substantial financial support for the production and use of fossil fuels, through direct payments, favourable tax treatment, and other actions. These subsidies keep the cost of fossil fuel energy artificially low, and make it harder for renewable energy to compete. They distort energy markets, encourage greater use of fossil fuels, create higher levels of greenhouse gas emissions, and improve the profitability of energy companies that produce or use fossil fuels. Calculated figures in 2011 put the total fossil fuel subsidies by the Australian government at AU$12.2 billion annually. This compared to just just AU$1.1 billion spent on climate policy such as support for renewables in 2010–11; furthermore, the funding gap between government climate change initiatives and fossil fuel subsidies had increased by AU$1 billion in the preceding three years.

Some business groups have lobbied the Australian government to prevent Australia from reducing greenhouse gas emissions, including representatives of the coal, oil, cement, aluminium, mining, and electricity industries.

Renewable energy programmes

Legislation to amend the federal Renewable Energy (Electricity) Act 2000, to create an Expanded Renewable Energy Target (ERET) was passed on 20 August 2009, with the broad aim of ensuring that renewable energy obtains a 20% share of electricity supply in Australia by 2020. To ensure this the government has committed that the MRET will increase from 9,500 gigawatt-hours to 45,000 gigawatt-hours by 2020.The scheme lasts until 2030.

 has responsibility for delivering several renewable energy programmes. It has policy responsibility for some financial incentives for the production and use of renewable energy, and for the Mandatory Renewable Energy Target (MRET) which requires an additional 9,500 GWh of electricity to be produced from renewable sources by the year 2010:
"The legislation behind MRET, the Renewable Energy (Electricity) Act 2000, came into effect on 1 April 2001 and requires electricity retailers and major electricity users to purchase a specified percentage of their electricity from renewable energy generators. These parties must acquire Renewable Energy Certificates (RECs) which demonstrate that they have sourced power from renewable energy generators. Each REC represents one megawatt hour of electricity. If an electricity retailer or major user hasn’t acquired enough RECs to meet their annual target under the legislation, they must pay a $40/MWh penalty."


Other Australian Government support for business, including renewable energy businesses, is delivered by the Department of Industry, Tourism and Resources.

Despite the Tambling review, the Howard government decided not to extend the Mandatory Renewable Energy Targets Scheme. However, various state Labor

 governments have recently announced their own renewable energy target schemes.

Politics of wind power

From 2001 to early 2006, the main driving force for the establishment of wind farms in Australia was the Government's Mandatory Renewable Energy Target or MRET. However, by mid-2006, sufficient renewable energy had been installed or was under construction to meet the small MRET target for 2010. Also, in 2006, several Federal Government Ministers spoke out against several wind farm proposals.

Leaked minutes from a 2004 meeting between leaders of energy intensive industries and the Australian government describe how both groups were worried that mandatory renewable energy targets were working too well and were "market skewed" towards wind power.

 has suggested that the Howard Government tried to stop the development of wind power, the lowest-cost, new, renewable electricity source, until such time as coal-fired power stations with CO2 capture and sequestration and possibly nuclear power stations are available.

Public opinion and action

Survey results suggest that there is considerable public support for the use of renewable energy and energy efficiency in Australia. In one recent survey, 74% of respondents favoured a "greenhouse strategy based mainly on energy efficiency and renewable energy, and 19% favoured an "approach that focuses mainly on nuclear power and clean coal technologies."

The Australian results from the 1st Annual World Environment Review, based on a survey of 1,007 people in 2007, found that:
  • 88% of Australians think that the Government should do more to increase the use of solar power. 78% say the government should do more to boost wind power, 58% hydro power, 50% tidal power, and 38% geothermal power, while only 25% think that the Government should do more to increase use of nuclear power.
  • 84% of Australians think that the Government should make it easier for people to buy renewable electricity.
  • 89% think that all electricity should contain a minimum 25% of power generated from renewable energy sources. Only 3% disagree.
  • 82% think that the Government should make it easier for people to buy solar panels.
  • 80% think that the Government should make it easier for people to buy energy efficient products, such as energy-saving light globes, water-saving shower heads and insulation etc.
  • 85% think that the Government should raise national fuel efficiency standards for cars and light trucks.
  • 87% think that the Government should do more to increase the number of cars that don’t use petrol.

Future prospects

Several recent reports have discussed the possibility of Australia setting a renewable energy target of 25 per cent by 2020. Combined with some basic energy efficiency measures, such a target could deliver 15,000 MW new renewable power capacity, $33 billion in new investment, 16,600 new jobs, and 69 million tonnes reduction in electricity sector greenhouse gas emissions.

 released a report in 2008 called "Energy [r]evolution: A Sustainable Energy Australia Outlook", detailing how Australia could produce 40% of its energy through renewable energy by 2020 and completely phase out coal-fired power by 2030 without any job losses.

David Spratt and Phillip Sutton argue in their book Climate Code Red that Australia (as part of a concerted global effort) needs to reduce its greenhouse gas emissions down to zero as quickly as possible so that carbon dioxide can be drawn down from the atmosphere and greenhouse gas emissions can be reduced to less than 325 ppm CO2-e, which they argue is the upper "safe climate" level at which we can continue developing infinitely. They outline a plan of action which would accomplish this.
