1. Do Now Name different forms of energy you and your family use in your daily lives. Recall the CCECHS blackout from last week. What was it like to not have power, even for just an hour?

2. Energy Resources: Fossil Fuels SWBAT describe the formation of fossil fuels and the role they play in our society

3. Until the industrial revolution, we could only harness the power of human and animal musclepower. The Industrial Revolution enabled us to exploit more powerful sources of energy, multiplying our capabilities.

6. Today, industrialized nations require huge amounts of energy to power their economies and produce goods and services. As global population grows, so will energy use. As people in undeveloped nations become richer, they will also use more energy.

8. There are 2 kinds of sources for our energy: 1.Non-renewable energy (energy for which we have a limited supply) 2.Renewable energy (energy for which the supplies are refreshed faster than humans use them)

9. Renewable or non-renewable?

10. What are the 4 non-renewable types of energy? Who uses more renewable energy: USA or the world?

11. Fossil Fuels Oil, Coal, and Natural Gas are the “fossil fuels”. Today, they supply 76% of the world’s total energy needs. Fossil fuels are burned to release heat, which is used to turn a turbine.

15. Oil, Coal and Natural gas were all formed through the same basic steps: 1.Over millions of years, the remains of organisms piled up underwater (where could not decompose). 2.These layers of remains were buried under sediments (like sand) for millions of years. 3.The deeper these layers were buried, the more they were heated and compressed. 4.This process “cooked” the remains in to fossil fuels.

16. Oil and Natural Gas were formed from sea- dwelling organisms such as microscopic phytoplankton and bacteria. As the remains of these creatures were “cooked” by heat and pressure, they first turned in to oil. If they were “cooked” more, they became natural gas.

18. Oil is used to make many products. This is done by boiling crude oil (a.k.a. petroleum), the natural form of oil. Different chemical compounds boil at different temperatures, and they are separated this way.

19. Coal A solid fossil fuel formed from dead land plants that were in ancient forests and swamps. Coal is the most abundant fossil fuel, but compared to oil and natural gas it is not as versatile, has a high environmental impact, and releases much more CO 2 into the troposphere.

20. COAL Figure 16-12

22. COAL Coal reserves in the United States, Russia, and China could last hundreds to over a thousand years. – The U.S. has 27% of the world’s proven coal reserves, followed by Russia (17%), and China (13%). – In 2005, China and the U.S. accounted for 53% of the global coal consumption.

23. Case Study: U.S. Oil Supplies The U.S. – the world’s largest oil user – has only 2.9% of the world’s proven oil reserves. U.S oil production peaked in 1974 (halfway production point). About 60% of U.S oil imports goes through refineries in hurricane-prone regions of the Gulf Coast.

24. 1.What are the 3 “fossil fuels”? 2.How are all fossil fuels formed? 3.How does the formation of coal, oil and natural gas differ? 4.What are 3 disadvantages of coal compared to oil and natural gas?
