  1. 17.1 Energy Resources and Fossil Fuels

  2. I. Fuels for different uses Fossil fuel – Remains of ancient organisms that changed into coal, oil, or natural gas Uses for fuel: Transportation b. Manufacturing c. Heating & Cooling d. Electricity Generation

  3. B. Electricity generation is the main use of fossil fuels The process of turning a fossil fuel into electricity: The fossil fuel is burned. The heat from the burnt fossil fuel is used to turn water into steam b. The steam is used to turn a turbine c. The turbine is connected to a generator that generates an electric current d. As the steam loses energy, it condenses and returns to liquid water. The water will be heated again and the process will start over

  5. II. Energy Use Energy use is much higher for people who live in developed countries Global oil usage: a. Unites States: #1 @ 20,680,000 bbl/day b. China: #2 @ 7,578,000 bbl/day c. Japan: #3 @ 5,007,000 bbl/day d. Russia: #4 @ 2,858,000 e. India: #5 @ 2,722,000 bbl/day 2. 25% of the energy produced in the united states is used for transportation and industry

  6. III. Formation of Fossil Fuels Coal – Formed from layers of sediment composed of plant remains Heat and pressure cause the plant remains to turn into coal Coal forms where swamps existed around 300 to 250 million years ago B. Oil and natural gas – Formed from marine organisms that accumulated at the bottom of the ocean million of years ago Heat and pressure cause the marine organisms to turn into oil and natural gas

  7. C. Coal: • Most of the world’s fossil-fuel reserves are made up of coal • 2. Coal is relatively inexpensive and it needs little refining after being mined • 3. Asia and North America are particular rich in coal deposits • 4. Over half the electricity generated in the United States comes from coal-fired power plants

  8. D. Petroleum • A liquid mixture of complex hydrocarbon compounds that is used widely as a fuel source. • 2. Petroleum, also known as crude oil. • 3. Anything that is made from crude oil, such as fuels, chemicals, and plastics, is called a petroleum product. • 4. Petroleum accounts for 45% of the world’s commercial energy use.

  9. E. Natural Gas: • About 20% of the world’s nonrenewable energy comes from natural gas. • 2. Natural gas, or methane (CH4), produces fewer pollutants than other fossil fuels when burned. • 3. Vehicles that run on natural gas require fewer pollution controls. • 4. Electric power plants can also use this clean-burning fuel.
