The Earth's Sources of Energy
Broad Concept: Numerous earth resources are used to sustain human affairs. The abundance and accessibility of these resources can influence their use.
|2.1 ||Recognize, describe, and differentiate between renewable (e.g., solar, wind, water, biomass) and nonrenewable (e.g., fossil fuels, nuclear [Ura-235]) sources of energy.|
|2.2 ||Explain the advantage and limitations of renewable sources of energy.|
|2.3 ||Explain the advantage and limitations of nonrenewable sources of energy.|
|2.4 ||Describe ways in which people have tried to control the use of renewable and nonrenewable sources of energy, e.g., scientific advances, prices.|
|2.5 ||Describe the effects on the environment of using both renewable and nonrenewable sources of energy.|
|2.6 ||Describe ways in which scientists are addressing effects on the environment of using both renewable and nonrenewable sources of energy, e.g., creation of new technologies.|
