Renewable Fuels – Biofuel
1. Any fuel with an 80% minimum content by volume of materials derived from living organisms harvested within 10 years of fuel manufacture
2. Ford’s “Model T” – 1st affordable automobile – designed to run on ethanol
3. The diesel engine – invented 1897 – was designed to run on biodiesel
4. Like coal, natural gas, and petroleum, biofuel is a form of stored solar energy
5. It is biodegradable

3. Non-edible Parts of FoodsAgricultural residues (peels, skins, husks, straw,
cores, fish heads)4. Algae
1) Yields of algal oil are greater than traditional oilseeds
2) Can grow for from farmlands and forests, minimizing damage to those ecosystems/food chains
3) Can be grown in sewages and next to smokestacks to digest pollutants and give oil

1. Vegetable Oil 1) Lower quality (not quite edible) used for fuel oil2) Used veg. oil increasingly used for biodiesel
Restaurant cooking oil sold/stolen and used2. Bioalcohols
1) Methanol, Ethanol, Propanol, Butanol2) Energy content comparable to gasoline3) “Flexfuel” systems can run on gasoline or ethanol

3. Biodiesel1) Diesel engine was invented to run on peanut oil2) Most common biofuel in Europe 3) Packs as much energy as its fossil fuel counterpart4) Can be used in existing diesel engines with little
modification5) Made from vegetable oils – soybean, canola, hemp6) Made from animal fats7) Made from algae

"The use of vegetable oils for engine fuels may seem insignificant today. But such oils may become in the course of time as important as the petroleum and coal tar products of the present time“
Rudolf Diesel, 1912

4. Biogas 1) Produced by anaerobic digestion of organic material
a) Anaerobic digestion – microorganisms break down biodegradables in absence of oxygen
b) Organic material – a once-living organism, capable of decay, or the product of decay
2) Landfills (70% of landfill) and other biodegradable wastes
3) Manure and other sources currently released into atmosphere
4) Biogas contains methane

5. Solid Biofuels – Biomass 1) Wood, sawdust, grass cuttings, domestic refuse,
charcoal, agricultural waste, non-food energy crops, and dried manure
2) When already in usable form (firewood), can be burned directly for heat or produce steam (for electricity generation)
3) When not in usable form, create pellets out of material to be burned in pellet stove
