As of 2021, Australia was the 12th-largest national economy by nominal GDP, the 18th-largest by PPP-adjusted GDP, and was the 25th-largest goods exporter and 20th-largest goods importer. Australia took the record for the longest run of uninterrupted GDP growth in the developed world with the March 2017 financial quarter. It was the 103rd quarter and the 26th year since the country had a technical recession. As of June 2021, the country's GDP was estimated at A$1.98 trillion. The Australian economy is dominated by its service sector, which in 2017 comprised 62.7% of the GDP and employed 78.8% of the labour force. Australia has the tenth-highest total estimated value of natural resources, valued at US$19.9 trillion in 2019. At the height of the mining boom in 2009–10, the total value-added of the mining industry was 8.4% of GDP. Despite the recent decline in the mining sector, the Australian economy had remained resilient and stable and did not experience a recession from 1991 until 2020. Petroleum, also known as crude oil and oil, is a naturally occurring, yellowish-black liquid found in geological formations. It is commonly refined into various fuels and chemicals. Components of petroleum are separated by means of distillation. Petroleum mainly consists of hydrocarbons as well as traces of other organic compounds. The name petroleum covers both naturally occurring unprocessed crude oil and petroleum products that are made up of refined crude oil. A fossil fuel, petroleum is formed when large quantities of dead organisms, mostly zooplankton and algae, are buried underneath sedimentary rock and subjected to both prolonged heat and pressure. Fuel oil (also known as heavy oil, marine fuel, bunker, furnace oil, or gasoil) is a fraction obtained from the distillation of petroleum (crude oil). It includes distillates (the lighter fractions) and residues (the heavier fractions). Oil has many uses; it heats homes and businesses and fuels trucks, ships, and some cars. A small amount of electricity is produced by diesel, but it is more polluting and more expensive than natural gas. It is often used as a backup fuel for peaking power plants in case the supply of natural gas is interrupted or as the main fuel for small electrical generators.
