Which statement is NOT TRUE about Thermal Mass?
Thermal mass is a property that allows a building material to retain heat or cold.
Materials with high thermal mass stay hot once they have been heated.
Stone and concrete have a high thermal mass
Wood and glass have low thermal mass
Materials with a positive thermal mass will stay cooled for a very short amount of time.
Which of the following is NOT a major form of Biomass energy?
wood and charcoal
animal products and manure
plant remains and MSW
ethanol and biodiesel
Municipal Solid Waste and Fossil Fuels
Why is energy from modern carbon potentially carbon neutral?
The carbon in biomass fuels may have been captured through photosynthesis as recently as a few months ago, in the case of a corn plants, or up to several hundred years ago, in the case of wood from a large tree.
Burning biomass should result in a net increase in atmospheric CO2 concentrations because the carbon it releases has recently been in the atmosphere.
O2 will be taken up by plants and not be released back into the atmosphere.
Biomass combustion emits more carbon monoxide which balances the carbon dioxide given off by plants making the atmosphere carbon neutral.
How can water be used as a renewable energy resource?
Moving water, either falling over a vertical distance or flowing with a river or tide, contains kinetic energy; turbines are turned by kinetic energy.
A Hydroelectric plant releases potential energy from moving water causing steam to turn turbines in a coal fueled power plant.
Water contains bioorganisms that over years pile up, decay and become crude oil.
Dammed water holds potential energy causing flooding and running water after rain.
What are the two types of hydroelectricity?
run-of-the-river system and water impoundment system
Reverse Stream Flow System and Dam Water System
Hydro Kinesis System and Hydroflow Rate System
MSW and Hydroenergy System
Which of the following is NOT a way that humans capture solar energy for their use?
Passive energy systems
Active energy systems
Photovoltaic energy systems
Solar thermal power plants
Solar Heat Exchanger
As water runs into an area that has been dammed it carries sediments that build up in the still waters near the dam called silt. Silt builds up and reduces the generating capacity and the lifespan of a dam.
How can siltation be fixed?
Silt removal is the only way to reverse excess siltation through dredging from behind the dam, using large equipment to dig it out.
Silt is biodegradable and over time will reduce opening the dam area.
The addition of fish to the impounded area will keep the bottom stirred up reducing the build up of silt near the dam area.
Opening the dam, allowing water to flow through, stirs up silt reducing sediment accumulation.
Aquatic plants use nutrients in silt reducing the amount of silt impaction.
The most common method of hydroelectric generation is
run-of-the river
tidal
water impoundment
gorge dams
siltation
Which of the following is NOT a disadvantage to photovoltaic cells?
