Energy

Non Renewable and Renewable

Fossil Fuels

Fossil fuels are formed from organisms that changed radiant energy from the sun to chemical energy. Fossil fuels are found in the earth.
This is a picture of where fossil fuels are found.

Petroleum

Gasoline, fuel oil, diesel, and kerosene are all made from petroleum.

Coal

Electric power plants burn around 90% of the coal that is used in the U.S. Coal is also used to heat buildings and make steel and concrete.

Natural Gas

Around half of all of the homes in the U.S. use natural gas for heating. Electric power plants burn about 30% of natural gas in the U.S. Burning creates less pollution than burning other fossil fuels.

Pros of Fossil Fuels

  • It is easy to transport.

  • There is a lot of it.
  • It is inexpensive to build and operate.

Cons of Fossil Fuels

  • Drilling/mining damages the earth.
  • Oil spills can harm wildlife.
  • It can produce air pollution.

Wind Energy

Big image
This is a picture of wind turbines.
Wind energy is an inexhaustible energy resource. Modern wind turbines convert kinetic energy in the wind to electric energy. The wind spins a propeller that is connected to the electric generator.

Wind Turbines

Wind turbines create no pollution in the air or water. But wind turbines can only be created where the average speed 5 m/s or more. Wind turbines cover large areas of land needed to obtain as much electric energy as one fossil fuel- burning power plant.

Pros of Wind Energy

  • Wind energy doesn't pollute air or water.
  • It can be used in isolated areas where there is no electric energy.

Cons of Wind Energy

  • Wind turbines can be noisy.
  • They are disrupting to wildlife.
  • It only works when wind is blowing.
