1. NONRENEWABLE AND RENEWABLE RESOURCES

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

3. NONRENEWABLE RESOURCES
A nonrenewable resource is a natural resource that cannot be re-made or re-grown at a scale comparable to its consumption.

4. NUCLEAR ENERGY
Formation: It is energy is stored in the nucleus (center) of an atom, and energy is in the bonds that hold the nucleus together. Splitting these bonds releases energy (fission)

5. Fission: Splitting these bonds releases energy
U = Uranium
Kr = Krypton
Ba = Barium

6. Nuclear energy is a nonrenewable resource because once the uranium is used, it is gone!

7. Characteristics of Nuclear Energy
Most widely used fuel from nuclear fission in Uranium (metal found in rocks)
1 pellet of uranium (Size of fingertip) = 150 gallons of oil
Produces dangerous radioactive waste
Does not pollute air

8. What is Nuclear Energy Used for?
We use the heat from fission to produce electricity
Nuclear Energy is also used to create bombs

9. 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.

10. HOW IS COAL MADE ???

11. HOW ARE OIL AND GAS MADE ???

12. WHAT WAS THE DIFFERENCE BETWEEN COAL AND OIL/GAS?

13. Oil - Formation AKA: Petroleum “oil from the Earth”
Oil is formed from the buried remains of microscopic marine (water) organisms and decayed plants

14. Oil - Characteristics
Thick black liquid
Most commonly used energy resource (39.4%)
Found in underground reservoirs

15. What is Oil Used for? Diesel fuel Jet fuel Gasoline
Propane (mix of natural gas and oil)
Ink
Crayons
CD’s and DVD’s
Dishwashing liquids
Deodorant
Tires

16. Natural Gas

17. Natural Gas Formation
Formed from buried remains of microscopic marine organisms and decayed plants. Gas escapes from small gaps.

18. Natural Gas – Characteristics
In a Gas form
Mostly methane (Which is a strong greenhouse gas)
2nd most commonly used resources (23.6%)

19. What is Natural Gas used for?
Propane Gas
Cooking/grilling
Paint
Fertilizer
Explosives
Used to heat ½ homes in U.S.
Production of:
Steel
Glass
Paper
Clothing
Electricity

20. Coal

21. How is Coal Formed
Dead plants in a swampy area are covered by more plants, H₂O, and sediments. Lack of Oxygen (O₂) causes plants to break down (AKA: Peat). Coal forms after millions of years.

22. Characteristics of Coal
Black or brownish sedimentary rock
Most abundant fossil fuel in U.S.
Compact
Brittle
Provides heat energy when burned
Can pollute environment
Extracted by mining
Strip mining: Dug up from surface of Earth
Open-pit mining: Tunnels are dug on side of hill or mountain

23. Open Pit and Strip Mining

24. What is Coal Used for?
93% used to generate electricity
Steel

25. HMMMM....
If nonrenewable resources are resources that cannot be re-made at a scale comparable to its consumption, what are renewable resources?

26. RENEWABLE RESOURCES
Renewable resources are natural resources that can be replenished in a short period of time.
● Solar ● Geothermal
● Wind ● Biomass
● Water

27. SOLAR
Formation:
Energy from the Sun is captured using solar cells/solar panels

28. Solar Energy Advantages
 Can be converted into Thermal (heat) energy  Can be converted into electricity  No pollution  When solar panels are on buildings there’s little impact on the environment

29. Solar Energy Disadvantages
 Amount of sunlight is not constant (depends on: location, time of day/year, and weather)  Requires a large surface for solar panels

30. GEOTHERMAL Break it Down: geo (Earth) thermal (heat) Formation:
Energy from within the Earth in the form of steam or hot water

31. Geothermal Advantages
 Heat is constantly produced inside the Earth and found everywhere
 Little to no pollution

32. Geothermal Disadvantages
Digging can destroy habitats
 Takes a lot of energy to dig wells (1-2 miles deep)

33. Energy from moving air caused by uneven heating of Earth’s surface
WIND
Formation:
Energy from moving air caused by uneven heating of Earth’s surface

34. Why does the Wind Blow?
Due to the uneven heating of the Earth's surface the cold air pushes the warm up creating the wind

35. Wind Advantages
 No pollution  Wind is free  Little harm to environment

36. Wind Disadvantages
 Requires very strong winds  Requires a large area for several windmills  Wind farm  Modern wind turbines are not pretty

37. BIOMASS
Formation: Energy from burning organic Material such as:

38. Biomass
1) Wood/plants stored solar energy
 can pollute when burned
 destroys habitats
 can replaces trees and plants

39. Biomass
2) Alcohol During distillation, biomass fuel, such as corn, is turned into an alcohol (ethanol)
 We put more energy into making it than the energy we get out of it
 Local use of energy

40. 3) Garbage Burning garbage produces heat
Biomass
3) Garbage Burning garbage produces heat
 Cheap
 produces toxic ash/air pollution

41. WATER or HYDROELECTRIC
Formation: Energy from moving H2O turn turbines at the end of dams that then turns generators to make elect. In U.S
Break it down:
Hydro (Water)
Electric (Electricity)

42. Hydroelectric Advantages
 Cheap
 No pollution

43. Hydroelectric Disadvantages
Up stream lakes fill with sediment and downstream erosion increases
Can cause floods
 Can cause damage to habitats

44. Examples of Hydroelectric Energy
Hoover Dam
tidal fences/turbines wave power
underwater wave energy
