Unit 5

Earth's Energy Resources Learning Target's:

  • through energy conservation, the total amount of energy in our universe will not change.

  • the use of Earth’s resources requires the consideration of advantages/disadvantages and ethical/social issues.

  • human consumption contributes to the need for research and development of energy resources.

    • the types of Earth’s resources:  coal, oil, natural gas, nuclear power, biomass, wind, hydropower, geothermal, and solar.

    • Earth's energy resources are categorized as either renewable (available on a nearly consistent basis) or nonrenewable (once depleted are essentially no longer available).

    • the total amount of energy remains the same yet the forms of energy can change (Law of Conservation of Energy) all energy can be stored or transferred in the form of potential or kinetic energy.

      • potential: chemical, nuclear, elastic, gravitational

      • kinetic: mechanical (motion), sound, thermal, electrical, radiant (electromagnetic/light)

    • energy transformations occur within many different systems in our everyday lives.

    • thermal energy can be transferred by conduction, convection, or radiation.
