Biofuels: more heat than light? – ISN

PORT MORESBY — The term ‘Biofuels’ might sound like a catchy green buzzword, but these alternatives to petroleum-based fuels have been around for a long time. The original Ford Model T was configured to run on ethanol rather than gasoline, and Rudolf Diesel ran his first demo engine on peanut oil. Biofuels were revived –  temporarily at least – by the 1970s oil embargo imposed by OPEC, as oil shortages and high fuel prices contributed to western economic stagnation. At the time, alternative energy sources were looked at, but subsequent economic revival and lower oil prices from the 1980s onward put these biofuels on the back burner Biofuels re-emerged in the late 1990s as the US mulled how to diversify its energy sources away from reliance on foreign oil imported from unstable or hostile states such as Venezuela, Saudi Arabia and Nigeria
