Did you know that Australia is the world’s fourth largest coal producer?1
Right now, coal is Australia’s primary fuel source for generating electricity at around 73 percent. Of this, black coal is used to generate around half of all our electricity (51 percent), while Victoria mainly uses brown coal (22 percent) because it’s mined in the state.2
Black coal is found across Australia. It gets its name from its colour and it has higher energy and lower moisture content than brown coal.3 The majority of Australia's black coal resources are located in Queensland and New South Wales in the Bowen, Surat and Sydney basins.4

Brown coal, sometimes called lignite, is a relatively soft material, which has a heating value of about one-quarter of black coal. It has much lower organic carbon content, higher moisture content, and is of lower quality than black coal.
Take a look at how the percentage of Australia’s coal-powered electricity generation compares with the rest of the world:6
Coal is Australia’s second largest export commodity, accounting for about 13 percent of Australia’s total exports in 2012-2013 and worth about $38 billion.7
Burning coal to generate electricity produces greenhouse gases, which cause climate change.
Brown coal is not as efficient at burning as black coal (because of its high moisture and low carbon content) and therefore it produces up to 30 percent more greenhouse gas emissions than black coal when used to generate electricity.
While coal remains one of the cheapest sources of electricity in Australia, and across the world, there’s a global movement towards a greater use of natural gas and renewable energy as communities realise the impacts of climate change.8
