Fuel

1
Fuel

• A substance that provides a form of energy as a
  result of a chemical change
• Heat
• Light
• Electricity
• Motion

2
Combustion

• The process of burning a fuel
• Always produces carbon dioxide and water

3
Production of Energy

• Produced from energy stored in fuels

4
Fossil Fuels

• Energy-rich substances formed from the remains of
  once-living organisms
• Coal, oil, natural gas

5
Coal

• Solid
• Formed from plant remains
• Burned to produce heat
• 23 of energy produced in U.S.

6
Oil

• Also called petroleum
• Thick
• Black
• Liquid
• Formed from remains of small animals, algae,
  protists that lived in the oceans millions of
  years ago

7
Locating Oil Deposits

• Very difficult b/c deep below the surface
• Use sounds waves to find oil
• 1 out of 6 wells drilled lead to usable sources
  of oil

8
Refining Oil

• Refinery-factory where crude oil is separated
  into fuels and other products by heating
• Petrochemicals-compounds that are made from oil
• Plastics, paints, medicines, and cosmetics

9
Natural Gas

• Mixture of methane and other gases
• Forms from same organisms as petroleum
• Pipelines are used to transport gas
• Several advantages
• Produces large amounts of energy
• Low levels of pollution
• Easy to transport
• Bad HIGHLY FLAMMABLE!

10
Fuel Supply and Demand

• Fossil fuels take hundreds of millions of years
  to form.
• For this reason, fossil fuels are considered a
  nonrenewable resource
• Uneven distribution causes political issues
• Trying to come up with new sources of energy to
  replace decreasing fossil fuels
