Fossil fuels are harmful to the environment, but they are still widely used. Australia imports a lot of oil, but could produce biofuels instead. Biofuels can reduce greenhouse gas emissions and make Australia less dependent on imported fuel. However, high costs have shut down many biofuel refineries. The government is trying to promote biofuel use with tax breaks, but more investment is needed. Building biofuel refineries locally could save money and reduce pollution. Biofuels could also create jobs and use land that is not being used for anything else.
