Explain how a global dependence on fossil fuels can lead to international security risks.
Which of the following is an example of a renewable resource?
Which of the following imports has increased over the past 6 years?
How do the uses of renewable resources compare to the uses of nonrenewable resources?
Both renewable and nonrenewable resources can be used to generate electricity, as a heat source, and for vehicle fuel. Not all types of renewable and nonrenewable resources can be used for every application, but at least one type of each can be used for each type of application. Renewable resources are more restricted by location than nonrenewable resources. Solar, wind, geothermal, and water energy use are dependent on location. Nonrenewable resources can be transported to locations where the resource is not readily available. The use of renewable resources typically has less environmental impact in the form of pollution than the use of nonrenewable resources.
