Overview

In this video from NOVA’s Energy Lab, learn about renewable energy sources and renewable energy technologies. A renewable source of energy is so plentiful that it can be considered limitless. Scientists and engineers are working on alternative energy technologies that make use of renewable energy sources (such as solar, geothermal, and tidal energy) and have less impact on the environment. The sun is our greatest energy resource; solar technologies use its energy directly in the form of light or heat, while other technologies use its energy after it has been converted into another form.

This video is available in both English and Spanish audio, along with corresponding closed captions.

SC15.4.5

Compile information to describe how the use of energy derived from natural renewable and nonrenewable resources affects the environment (e.g., constructing dams to harness energy from water, a renewable resource, while causing a loss of animal habitats; burning of fossil fuels, a nonrenewable resource, while causing an increase in air pollution; installing solar panels to harness energy from the sun, a renewable resource, while requiring specialized materials that necessitate mining).

Knowledge

Students know:
  • How energy is derived from natural resources.
  • How energy resources derived from natural resources address human energy needs.
  • Positive and negative environmental effects of using each energy resource.
  • The role of technology in improving or mediating the environmental effects of using a given resource.

Skills

Students are able to:
  • Waves, which are the regular patterns of motion, can be made in water by disturbing the surface.
  • When waves move across the surface of deep water, the water goes up and down in place; there is no net motion in the direction of the wave except when the water meets a beach.
  • Waves of the same type can differ in amplitude (height of the wave) and wavelength (spacing between wave peaks).

Understanding

Students understand that:
  • Energy and fuels that humans use are derived from natural sources, and their use affects the environment in numerous ways.
  • Resources are renewable over time, while others are not.
