1. Energy RESOURCES

2. What do you think nonrenewable resources are?
HMMMM....
What do you think nonrenewable resources are?
Break it down...
Nonrenewable?
Resource?

3. 1. NONRENEWABLE RESOURCES
A natural resource that cannot be re-made or re-grown in a reasonable amount of time….that is, we can use it up faster than it can be remade.

4. 2. COAL, PETROLEUM, AND GAS
Coal, petroleum, and natural gas are considered nonrenewable because they can not be replenished in a short period of time. These are called fossil fuels.

5. 3. They are 85% of the world’s commercial energy.
COAL
NATURAL GAS
OIL

7. 4. HOW IS COAL MADE ???

8. last 200 years at present rate
5. What is COAL?
Fossilized, condensed
carbon-rich fuel
10 X reserves of oil/gas,
last 200 years at present rate

9. 6. Effects on health a. Black Lung Disease (miners)
b. Respiratory illnesses
(public)

10. 7. Effects on land Coal sludge releases Hardpan at strip mines
Mountaintop removal
Huge water use
Slurry pipelines

11. 8. Effects on air Greenhouse gases Toxics sulfur dioxide
nitrogen oxides
carbon dioxide
Toxics
Mercury
Uranium

12. 9. Acidity of rain pH of 6.0 pH < 5.0 Kills insects, crabs
Kills fish, trees

13. HOW ARE OIL AND GAS MADE ???

14. 11. Advantages of natural gas
a. Cleaner to burn - Half as much CO2 as coal
b. More efficient – only 10% energy lost

15. 12. Disadvantages of natural gas
a. Difficult to transport
b. Can be polluting

16. 13. OIL (PETROLEUM)
Buried organic matter
rich in hydrocarbons

17. HMMMM....
If nonrenewable resources are resources that cannot be re-made, what are renewable resources?

18. 14. RENEWABLE RESOURCES
Natural resources that can be replenished in a short period of time.
● Solar ● Geothermal
● Wind ● Biomass
● Water

19. 15. SOLAR
Energy from the sun.

20. Energy from Earth’s heat.
16. GEOTHERMAL
Energy from Earth’s heat.

21. Why is energy from the wind renewable?

22. 18. BIOMASS Energy from burning organic or living matter.
Why is energy from biomass renewable?

23. 19. WATER or HYDROELECTRIC
Energy from the flow of water.
Why is energy of flowing water renewable?

24. SUMMARY
What are the differences between nonrenewable and renewable resources?
