Biofuels are an alternative to fossil fuels. They include aegis ethanol and derivatives of plant sources such as sugar cane, and vegetable oils. According to The International Energy Agency (IEA), biofuels may comprise as much as 10% of the global gasoline supply by 2025.
However, we are still in the process of developing biofuels that have the same energy efficiency of petroleum-based gasoline. Many nations are investing in biofuels. For example, Brazil has an ethanol output of 3 ½ billion tones/ year.
