Now You Know

After completing this tutorial, you will be able to complete the following:

  • Identify wind power, solar energy, tidal power plants, and geothermic power plants as sources of renewable energy.
  • Explain why some resources are considered renewable.
  • Describe transformations of energy generated by renewable energy sources into electrical energy.

Everything You'll Have Covered

Energy can be converted and stored in different areas, and is often used to provide electricity for human beings. Various energy sources, such as coal and nuclear energy have been used to produce electricity, but these sources are not renewable. It takes a long time to replenish these supplies.

Renewable energy is generally re-supplied quickly by natural sources, such as the Sun, weather, and Earth's inner core. The renewable energy sources described in the Activity Object include tidal power, solar power, wind power, and geothermal power.

Tidal and wind energy convert mechanical energy into electrical energy. These processes generally utilize a turbine to create mechanical energy. Geothermal energy converts heat energy into mechanical energy, and then into electrical energy.

In the solar energy process, light hits photovoltaic cells and an electron breaks loose. This electron is collected, and contributes to the electric current. Solar energy cells are used to provide electricity to homes. They can also power calculators and charge batteries.
