ENERGY RESOURCES BIOMASS BIOGAS QUIZ
1. Wood and Wood wastes were main source of ________ in mid-1800s
a/ machine
b/ I don't listen that much to presentation
c/ energy
d/ water
e/ None of the above
2. . Which of the following cannot be considered biomass ?
a/ Wastewater from your shower, bathtub, washing machine, dishwasher, kitchen sink and
toilet is all considered sewage. It isn't just from the toilet.
Interestingly, sewage is actually 99.8% water.
b/ Agricultural residues. The most significant division is
between those residues that are predominantly dry (such as
straw) and those that are wet (such as animal slurry).
c/
Biomass resources include plant and animal material such
as wood from forests, material left over from agricultural and forestry processes.
d / All types of solid waste generated
by households and commercial establishments, and collected
usually by local government bodies
/
e/ None of the above
3. What can be Biomass made out of?
a/ Garbage and People
b/ Water and Dirt
c/ Wastes and Wood
d/ None of the above
4. Biogas typically refers to a mixture of different gases produced by the breakdown of
organic matter in the absence of oxygen. Biogas can be produced from raw materials
such as agricultural waste, manure, municipal waste, plant material, sewage, green
waste or food waste. It is a renewable energy source and in many cases exerts a very
small carbon footprint. It is produced by the action of
a. the government
b. Bacteria
c. The air
d. No idea!
e.
5. The process of digesting organic waste material can occur in digesters that we have built, or
naturally underground in ………………… sites
a. Landfill
b. Metro
6. The gas can be used to power ………… and used for heating ………in homes and
businesses
a. Vehicles / and cooking
7. s a type of waste which can be broken down, in a reasonable amount of time, into its
base compounds by micro-organisms and other living things
8. Biogas is a mixture containing ……………….
a/ Methane (CH4), Carbon dioxide (CO2), nitrogen (N2), hydrogen(H2), hydrogen
sulphide (H2S), Oxygen (O2)
b/ Carbon dioxide (CO2), Methane (CH4), Nitrogen (N2), Hydrogen(H2), Hydrogen
sulphide (H2S),
c/ None of above!
9. In North America, use of biogas would generate enough electricity to meet up to 3%
of the continent's electricity expenditure. In addition, biogas could potentially help
reduce global climate change. High levels of methane are produced when manure is
stored under anaerobic conditions. By converting cow manure into methane biogas via
anaerobic digestion, the millions of cattle in the United States would be able to
produce 100 billion kilowatt hours of electricity, enough to power millions of homes
across the United States. In fact, one cow can produce enough manure in one day to
generate 3 kilowatt hours of electricity; only 2.4 kilowatt hours of electricity are
needed to power a single 100-watt light bulb for one day. Furthermore, by converting
cattle manure into methane biogas instead of letting it decompose, global warming
gases could be reduced by 99 million metric tons or 4
10. In the 1985 Australian film Mad Max Beyond Thunderdome the post-apocalyptic
settlement Barter town is powered by ………….. system based upon a piggery. As
well as providing electricity, methane is used to power Barter's vehicles
a/ central biogas
b/ high rpm diesel engine
c/ sledges pulled by biomass
d/ who cares!
