Unit 3 Using Resources, Lesson 3 Energy Resources Quiz

What is the energy source in which a dam plays a key role?

• wind energy

• active solar

• • 
    

    hydroelectric

• geothermal

A community is faced with the burden of rising landfill costs. An environmental consultant explains that these costs can be cut in half over a five-year period. The consultant uses the following data from a nearby town to illustrate this point.

What else could the consultant do that would help demonstrate how to solve the community’s problem?

• Provide a computer model that demonstrates the advantages and efficiencies of curbside pickup.

• Read a report that highlights the need to build multiple new landfills to accommodate the number of reusable materials added.

• Present a flow chart showing how to scale this problem to national and global levels.

• Form a focus group that would be able to address all problems in year one of the project timeline.

What is a heating system that uses solar collectors?

• geothermal power plant

• • 
    

    active system

• passive system

• photovoltaic cell

An engineering team is developing a new type of solar panel that can provide electrical energy more cheaply and efficiently than existing models. Initial tests of a prototype, however, reveal that the ceramic material used in its construction has a lower-than-expected efficiency. Which statement best describes how the researchers could optimize the design?

• Make adjustments to the ceramic material, and retest the design.

• Construct a different design that is expected to have higher efficiency.

• Identify the end goal of what the solar panel must be able to do.

• Use available information, and brainstorm ideas for the solar panel design

What is one disadvantage of wind energy?

• It is difficult to transport the energy from its source to where it is needed.

• • 
    

    Wind turbines generate only a small amount of energy.

• • 
    

    Large amounts of farmland are needed for the turbines.

• Wind turbines are not cost-effective.

What type of energy does a well that is drilled to reach hot water heated by magma harness?

• hydroelectric energy

• solar energy

• nuclear energy

• • 
    

    geothermal energy

What is the source of 7% of the United States’ electricity?

• geothermal power

• hydroelectric energy

• biomass

• wind energy

A design team is discussing how to remodel a city factory to make it as energy efficient as possible. Which statement describes a way the team constrains the project? Choose the correct answer.

• They analyze possible construction methods, such as which materials to use in the renovation.

• They conduct a series of tests to make sure the factory does not pollute local water supplies

• They determine the cost and the time that will be necessary to make the factory energy efficient.

• They identify various features that they want to incorporate into the design to minimize pollution.

Which statement describes solar power plants?

• They are more expensive than nuclear power plants to install and maintain.

• They are inexpensive to install but expensive to maintain.

• They are less expensive than coal power plants to operate.

• They are one of the most expensive power plants to operate.

What is one of the main limitations of using solar energy to generate electricity?

• • 
    

    Maximum efficiency of solar systems is very low.

• Solar systems are difficult to install.

• It is unpredictable in different seasons.

• It cannot be connected to the electrical grid.
