The Sources!

• Alternative energy is an umbrella term that
  refers to any source of usable energy intended to
  replace conventional energy sources without the
  undesired consequences of the replaced sources.
• They are divided into 5 categories
• Solar energy (generation of electricity from
  sun)
• Wind energy (generation of electricity from
  wind)
• Geothermal energy (using hot water or steam
  from the Earths interior for heating buildings
  or electricity generation)
• Biofuel and Ethanol (plant-derived substitutes
  of gasoline for powering vehicles)
• Hydrogen (used as clean fuel for airplanes,
  spaceships, and vehicles)
