How are resources used?
Renewable options
Types of Biofuels
Bioalcohols: alcohols synthesized chemically or biologically, have high octane rating (which means they can ignite well) but lower energy density
Types of Biofuels
Biogases: gases produced by biological breakdown of organic matter (without O2)
Types of Biofuels
Biodiesels: clean burning alternative fuel, produced from domestic, renewable resources
How available are these types of biofuels?How efficient is each type of biofuel?
