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 policies for energy in Australia continue to support the coal mining and natural gas industries through subsidies for fossil fuel use and production. Australia is the 10th most coal-dependent country in the world. Coal and natural gas, along with oil-based products, are currently the primary sources of Australian energy usage and the coal industry produces over 30% of Australia's total greenhouse gas emissions. In 2018 Australia was the 8th highest emitter of greenhouse gases per capita in the world.
Energy in Victoria, Australia is generated using a number of fuels or technologies, including coal, natural gas and renewable energy sources. Brown coal, historically, was the main primary energy source for the generation of electricity in the state, accounting for about 85% of electricity generation in 2008. The amount of coal-fired power has decreased significantly with the closure in 2017 of the Hazelwood power station which supplied around 20% of Victoria's electricity, and to a lesser extent with the exit of Anglesea power station in 2015. Brown coal is one of the largest contributors to Australia's total domestic greenhouse gas emissions and a source of controversy for the country. Australia is one of the highest polluters of greenhouse gas per capita in the world.
