1. Turn in your OLD flashback sheet

2. Traditional Sources of Energy
Harvesting of field crops, wood, fecal material and peat

3. Traditional Sources of Energy – pg. 684
Create a Graphic Organizer that represents the 4 types of traditional sources of energy.
For each type, be sure to include at least 3 important facts.

4. What is 1 traditional source of energy?

5. Fuel is a necessary part of life
Where does it come from?

6. The plants of forests that once covered Earth provide us with the energy we use today.

7. This energy is stored in fuels

8. Fossil Fuels formed from the remains of plants and animals that were buried for millions of years

9. Types of Fossil Fuels: Coal Oil (petroleum) Natural Gas
Coal forms from mostly plants
Oil forms from mostly simple organisms – bacteria, algae, etc..

10. Coal – organic sedimentary rock
Varies in the amount of carbon
more carbon = more energy

11. Different types of Coal
Peat Low Energy
Lignite
Bituminous
Anthracite High Energy

12. HOW IS COAL MADE ???

14. Petroleum – organic liquid plant/animal remains
Contains carbon and hydrogen
Refined as gasoline, kerosene, lubricants, etc.
Must drill wells to tap source
Often found with natural gas

15. HOW ARE OIL AND GAS MADE ???

17. Natural Gas Chain of hydrocarbons created with petroleum
Can be used as an energy source

18. Natural Gas Extraction
“Fracking” Technique for extracting natural gas from “tight” rock(shale) structures deep below surface
Has been used since 1950’s

19. Fossil Fuels do not create energy, they store energy
Where does the energy come from?
The stored energy came from the sun!

22. Burning fossil fuels increases the amount of greenhouse gases in the atmosphere, ice caps melt, ocean levels rise…
