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.

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
