In 300 BC, the Syrian city of Antioch had public street lighting fuelled by olive oil. At the 1900 Paris World Fair, German inventor Rudolph Diesel demonstrated his engine powered by peanut oil. Biofuels are not new, but many of the technologies are, and interest in renewable, sustainable biofuels has recently been rising due to worry about peak oil and price pressures, vulnerability of energy supplies, dependence on imports, and greenhouse emissions. In April this year,
Qantas made its first flight using a 50-50 blend of refined cooking oil and regular jet fuel. Qantas chief executive Alan Joyce told the Australian: “We need to get ready for a future that is not based on traditional jet fuel or frankly we don’t have a future … And it’s not just the price of oil that’s the issue – it’s also the price of carbon”. Australia’s tax on carbon emissions is scheduled to come into force on 1 July 2012.
