GASOLINE & PETROLEUM
The most commonly used biofuel today - made from biomass that died millions of years ago (think dinosaurs and ancient jungle growth!) Also, the leading cause of global warming. Hmmm... What are some other options?
CORN
Yup, fuel made from corn! Emissions are lower, but not by much. Growing all that corn may also require more energy than it actually produces.
SUGAR CANE
A totally sweet fuel! Fuels made from sugar cane crops can reduce greenhouse gas emissions by up to 56%! A big success so far in Brazil.
SWITCHGRASS
This amazing plant turned biofuel can reduce greenhouse gas emissions by up to 90%! Some kinds of switchgrass can also remove CO2 from the atmosphere and store it in the ground.
USED COOKING GREASE
The cooking oil used to deep fry things like french fries and chicken wings can be recycled into fuel! Fuel made from used cooking grease releases fewer gases and is a great way to REUSE something that would have been thrown away.
KELP
Scientists have recently found that seaweed can be used for fuel as well. Breaking down the sugars in kelp can create five times as much ethanol as corn.
