Renewable Sources of Energy

  • Sources of energy that are constantly being supplied.
  • Examples-Sunlight, wind, and trees are naturally replaced in a short amount of time.

Energy from the Sun

  • Solar energy-the sun constantly gives off energy in the form of light and heat.
  • Solar energy does not cause pollution and it will not run out for billions of years.

Wind

  • Wind energy is free and does not cause pollution.
  • Wind now provides less than one percent of the world’s electricity but it is the fastest growing energy source.

Water

  • As water flows over the land into lakes and oceans, it provides another source of energy.
  • Hydroelectric power is electricity produced by flowing water. It is the most widely used source of renewable energy in the world today. It is inexpensive and does not cause pollution.

Biomass fuels

  • Biomass fuels are fuels made from things that were once alive.
  • Examples: wood, leaves, food wastes, and manure.
  • Burning breaks down complicated materials in these fuels, releasing energy. Biomass materials can be converted into other fuels.
  • Biomass fuels are not widely used today.

Geothermal Energy

  • Geothermal Energy is when magma heats underground water to its boiling point and the hot water and steam are used as sources of energy.
  • Geothermal energy can be used to generate electricity and is an unlimited source of cheap energy.

Non-Renewable Resources (Fossil Fuels)

  • A fuel is a substance that provides a form of energy-such as heat, light, electricity, or motion.
  • The energy stored in fuels can be used to generate electricity.
  • Fossil fuels are the energy-rich substances that formed from the remains of once-living organisms.
  • Fossil fuels are made of hydro-carbons.

Three types of Fossil Fuels

1. Coal 2. Oil/Petroleum 3. Natural Gas

Coal

  • Coal is a solid fossil fuel formed from plant remains.
  • Coal is burned to produce heat.
  • Coal provides 23 percent of the energy used in the United States.
  • Coal is the most plentiful fossil fuel in the U.S.

Oil/Petroleum

  • Oil is a thick, black liquid fossil fuel. It is formed from the remains of small animals, algae, and protists that lived in the ocean millions of years ago
  • Oil accounts for more than one third of the energy produced in the world.
  • Oil is used for fuel for most cars, airplanes, trains, and ships.
  • Only three percent of the world’s supply is located in the U.S. The difference must be purchased from countries with large oil supplies.

Natural Gas

  • Natural Gas is a mixture of methane and other gases.
  • Produces large amounts of energy and causes less pollution than oil and coal. It is easy to transport through a network of pipelines underground.
  • One disadvantage is gas is highly flammable.

Fuel Supply and Demand

  • Fossil fuels have become essential to modern life.
  • Remember that fossil fuels take hundreds of millions of years to form.
  • Fossil Fuels are considered nonrenewable resources-natural resources that are not replaced as they are used.

Producing Electricity at a Power Plant

Different types of power plants produce electric energy by using different types of fuel.
