Biofuels are fuels made from plants or other organic matter. In Australia, biofuels are commonly used in cars, boats, and other vehicles. This is done by mixing the fuel with petrol or diesel, which makes the fuel burn more efficiently and lowers emissions. Biofuels are a clean and sustainable alternative to petrol and diesel, meaning that they don't cause as much environmental harm. They also help reduce Australia's reliance on imported fuel, saving money and creating jobs.
