Energy policy of Australia
The energy policy of Australia is subject to the regulatory and fiscal influence of all three levels of Government in Australia, although only the State and Federal levels determine policy for primary industries such as coal.Federal energy policies continue to support the coal mining and natural gas industries through subsidies for fossil fuel use and production as the exports by those industries contribute significantly to the earnings of foreign exchange and government revenues. Australia is one of the most coal-dependent countries in the world. Coal and natural gas, along with oil-based products, are currently the primary sources of Australian energy usage, despite the fact that the coal industry produces approximately 38% of Australia's total greenhouse gas emissions. Federal policy has reverted to a pro-coal economy with drastic cuts to alternate and renewable energy government offices, targets and subsidies ""With proposals to repeal the carbon price, dismantle the Climate Change Authority and the Clean Energy Finance Corporation, and the dilution of the Renewable Energy Target already in train, the budget measures, which include the closure of the Australian Renewable Energy Agency, the dumping of the million solar roofs program (both contrary to election promises) and the research funding cuts at the CSIRO, Bureau of Meteorology and elsewhere,...the obliteration of the Clean Energy Future package] is complete"". The Conservative government has implemented many of the 75-point wish list drawn up by the influential Institute of Public Affairs. The Institute of Public Affairs (IPA) is a right-wing, corporate funded think tank based in Melbourne. It has close links to the Liberal Party of Australia. The IPA's key policy positions include: advocacy for privatisation and deregulation; attacks on the positions of unions and non-government organisations; support of assimilationist indigenous policy (cf. the Bennelong Society) and refutation of the science involved with environmental issues such as climate change. Federal policy was beginning to change during the previous Liberal government with the publication of the Garnaut report and Carbon Pollution Reduction Scheme White Paper, the announcement of an Emissions Trading Scheme to commence in 2010, and the announcement of a national mandatory renewable energy target of 20% of electricity supply in Australia by 2020.State energy policies such as Mandatory Renewable Energy Targets ensure that renewable energy contributes a greater percentage of the country's energy supply.Due to Australia's reliance on coal and gas for energy, in 2000 the country was the highest emitter of greenhouse gases per capita in the developed world, irrespective of whether or not emissions from land clearing were included. It is also one of the countries most at risk from climate change according to the Stern report.Renewable energy commercialisation in Australia is an area of relatively minor activity compared to the fossil fuels industry. Australia's renewable energy industries are diverse, covering numerous energy sources and scales of operation, and currently contribute about 8–10% of Australia's total energy supply. The major area where renewable energy is growing is in electricity generation following the introduction of government Mandatory Renewable Energy Targets. The two most populous states, New South Wales and Victoria have renewable energy targets of 20% and 25% respectively by 2020.
