Renewable Energy

• Biomass
  Biomass consists of growing plants or the remains of growing things. Examples include trees, grasses, algae, ocean plants, agricultural and food processing wastes, manure, and even garbage.
• Geothermal
  Geothermal energy is the natural heat of the earth, found near areas where volcanic activity has taken place.
• Hydropower
  Water flowing in streams or through pipes can be used to produce electricity.
• Ocean Thermal Energy
  Ocean thermal energy conversion (OTEC) uses the difference in temperature between the warm surface of the ocean and the cold ocean depths.
• Solar
  Energy from the sun is commonly used to heat water (this is called a "solar thermal" system) and to produce electricity (this is called a "photovoltaic" system).
• Wave
  Energy from ocean waves, tides, or currents can be used to produce electricity.
• Wind
  Energy from the wind can be used to produce electricity.
• A Catalog of Potential Sites for Renewable Energy in Hawaii

• How is electricity produced?
  Magnet plus wire plus motion equals electricity.
