Q: What is a first generation biofuel?
- Ethanol derived from cellulosic materials, such as switchgrass or miscanthus
- Ethanol derived from the fermentation of sugars, derived from crops such as wheat, corn, or sugar cane
- Pretreatment of cellulosic biomass to break apart and release sugars for fermentation to ethanol
A: Ethanol derived from the fermentation of sugars, derived from crops such as wheat, corn, or sugar cane

Q: What are second generation biofuels?
- Ethanol derived from cellulosic materials, such as switchgrass or miscanthus
- Ethanol derived from the fermentation of sugar and starch crops, such as wheat, corn, or sugar cane
- Pretreatment of cellulosic biomass to break apart and release sugars for fermentation to ethanol
A: Ethanol derived from cellulosic materials, such as switchgrass or miscanthus

Q: True or False: The technical parameters for biopower (electricity generated from combustion of biomass) are well developed.
- True
- False
A: False

Q: How are liquid and gas biofuels produced?
- Fermentation (to produce bioethanol)
- Gasification (to produce syngas)
- Pyrolysis (to produce syngas and char)
- Torrefaction (to produce bio-coal)
- Transesterification (to produce biodiesel)
- Anaerobic digestion (to produce pipeline quality gas)
- All of the above
A: All of the above

Q: Why is it important to develop combined heat and power (CHP) units?
- Federal policy mandates it
- Large scale electricity generation facilities have invested heavily in it
- Combined heat and power is many times more efficient than combustion for electricity generation alone
A: Combined heat and power is many times more efficient than combustion for electricity generation alone

Q: What are potential reasons that an electric utility might opt to burn woody biomass in a power plant?
- To meet renewable energy standards
- To reduce amount of materials that would have to be transported to the boiler
- To cut back on pollution from coal burning
- To improve boiler efficiency
- A and C above
- B and D above
A: A and C above

Q: What are the main sources of woody biomass?
- Forests
- Agriculture
- Sawmill waste
- A & B above
- A & C above
A: A & B above

Q: What are the main types of agriculture based energy crops?
- Corn, switchgrass, and miscanthus
- Soybean, sunflower, and canola
- Willow and poplar
- Perennial lignocellulosic crops, lignocellulosic residues, sugar and starch crops, and oil-producing crops
- Corn stover, rice chaff, oat husks
A: Perennial lignocellulosic crops, lignocellulosic residues, sugar and starch crops, and oil-producing crops

Q: What are examples of waste-based feedstocks?
- Sawdust
- Landfill gases
- Construction wastes
- Compostable materials
- Manure
- All of the above
A: All of the above

Q: True or False: Bioenergy co-products are insignificant in determining the profitability of a bioenergy enterprise.
- True
- False
A: False
