ESS3.2 Renewable and Alternate Sources of Energy

Which of the following resources is a renewable resource?

• Hydropower, because water will not be replenished as quickly as we use it.

• Crude oil, because oil is highly sustainable.

• Natural gas, because it is replaced as quickly as we use it.

• Solar power, because it is replenished faster than we use it.

A student at The University of Tennessee is writing a speech about the increased need for technology using solar power. Which statement would best support his claim?

• Solar panels can take up large amounts of space and cause habitat loss.

• Solar power technology is expensive, and access to solar energy is only available at certain times.

• Some nonrenewable resources such as silver are used in the production of PV Cells.

• Solar power emits no greenhouse gases when used, and recent technologies have allowed us to increase efficiency by absorbing larger amounts of the sun’s energy per solar panel.

The University of Tennessee is currently planting switchgrass in Knoxville and the surrounding areas. The switchgrass will be used to create a fuel source so that we are less dependent on oil-based fuels. Which renewable resource are researchers using?

• Solar Power

• Hydropower

• Biomass

• Fuel cells

The use of switchgrass will benefit Tennessee citizens because… (3 answers)

• Switchgrass is a renewable resource because it can regrow (replenish) quickly

• If we use more land for producing switchgrass, it could cause habitat loss for some species.

• The production of fuel using switchgrass will provide more jobs in Tennessee

• The use of alternative fuels, such as fuel made from switchgrass, will help us to be less dependent on foreign oil.

What answer differentiates renewable resources from nonrenewable resources?

• Nonrenewable resources can easily replaced while nonrenewable resources cannot

• Renewable resources can be easily replaced while nonrenewable resources cannot

• Nonrenewable resources will not run out if we continue using them the way we have been

• Renewable resources will run out in the near future if we are not careful

The word sustainability refers to…

• The using up of a resource

• The variety of species in an ecosystem

• The ability to keep something in existence

• The amount of something that can be used or obtained
