  • Sources of Tidal PowerAlternative Energy Primer

    But what are the sources of tidal power What drives the twice daily motion of all that water Tidal energy is unique in that it derives from the gravitational pull of the moon and to a much lesser extent the sun. This is unique because virtually all other forms of energy on planet earth derive ultimately radiation energy from the sun.

  • How Do Wind Turbines Work Department of Energy

    The terms "wind energy" and "wind power" both describe the process by which the wind is used to generate mechanical power or electricity. This mechanical power can be used for specific tasks (such as grinding grain or pumping water) or a generator can convert this mechanical power into electricity.
