FOSSIL FUELS

FOSSIL FUELS. What are fossil fuels?. Fossil fuels (coal, oil and natural gas)are forms of stored energy that are formed when plant and animal remains are trapped in the earth’s crust for millions of years and heat and pressure act on them. Natural Gas. Coal. Oil.

  1. FOSSIL FUELS

  2. What are fossil fuels? • Fossil fuels (coal, oil and natural gas)are forms of stored energy that are formed when plant and animal remains are trapped in the earth’s crust for millions of years and heat and pressure act on them Natural Gas Coal Oil

  3. Why are fossil fuels important • Fossil fuels are used to produce heat and also power machines in factories. • Fossil fuels power machines called turbines that help produce electricity • Fossil fuels are refined to make gasoline used by cars Turbines Gasoline

  4. Evaluating Energy Resources • The types we use determine our quality of life and the amount of harmful environmental effects • Questions to ask ourselves: • How much of the energy source will be available in the future? • What is this source’s net energy yield? • How much will it cost to develop, phase in, and use this resource? • How much will extracting, transporting, and using the energy resource affect the environment? • What will using this energy source do to help sustain Earth?

  5. Net Energy The total useful energy available from the resource over its lifetime minus The amount of energy used, lost, and wasted in finding, processing, concentrating, and transporting it to uses

  6. COAL Fossil Fuels

  7. OIL Fossil Fuels

  8. NATURAL GAS Fossil Fuels Natural gas is commonly used as a source of heat for cooking

  9. Poster & Gallery Walk • On your poster you must include the following: • Title • Picture • What is this fossil fuel and how is it formed? • Where is this fossil fuel found and how do we find it? • How do we use this fossil fuel and what is the net energy yield? • What are the benefits (pros) of this fossil fuel? • What are the cons for this fossil fuel? • Information needs to be easy for others to find.

  10. When fossil fuels are burned in excess, they can cause air pollution

  11. Fossil fuels: Reduce, Reuse & Recycle • Fossil fuels are non-renewable resources and therefore they have to be used wisely • Excess burning of fossil fuels releases a lot of carbon dioxide gas into the atmosphere • Excess carbon dioxide destroys the earth’s ozone layer which protect us from skin cancer

  12. Fossil fuels are unevenly distributed What % of the world’s oil does Iraq have? What % of the world’s natural gas does the U.S. have? 3.0% 9.6% Why do you think some countries have more fossil fuels than others?

  13. Usage of fossil fuels Global consumption of fossil fuels is at its highest level ever. How much does the average American use compared to the average Indian? The average American uses 100 times more energy than the average Indian.

  14. When in your day do you use fossil fuels?
