1. The types of energy in our world
Energize!
The types of energy in our world

2. What are natural resources?

3. Natural resources are items we take from the Earth to use for living.
Who makes natural resources?
Can you name some natural resources?

4. Two types of natural resources:
Nonrenewable Resources
2. Renewable Resources

5. Nonrenewable Resource:
A resource we get from the earth, that we can run out of someday. Once these resources are gone, we can NEVER get them back again in our lifetime.
Fossil fuels
Petroleum oil
Natural gas
Coal

6. Fossil Fuels takes millions of years to form (make)
animals and plants die and are buried under layers of sedimentary rock
Types of fossil fuels:
coal
natural gas
oil
Gasoline is NOT a fossil fuel but fossil fuels are used to make gasoline/petroleum

7. Fossil fuels are natural resources.

8. Fossil fuels are made out of plants and animals that died many, many years ago…..over 50 thousand years ago. Here is how it
goes…

9. Plants or animals die
Bummer, I died!

10. Sediments pile up on top of the plant or animal’s body for thousands of years.

11. The body starts to rot under all of that pressure from the layers.

12. This takes many hundreds of thousands of years to happen.

13. The rotted body and plants start to decompose and turns into fossil fuels.

14. Humans dig into the ground to dig out the fossil fuels.

16. We mine out the COAL.

17. Coal

19. and burn it in electric companies to make steam to make turbines spin to make electricity for our homes.

20. But Coal creates A LOT of pollution.

21. Or we bring it out
in oil wells…..

22. Petroleum / Oil
Wells used today
Old wells

23. Oil can be found on land or in the ocean

24. once again to burn it in electric companies to make steam to make turbines spin to make electricity for our homes.

25. But oil creates A LOT of pollution too.

26. Or we pump it out as natural gas..

27. Natural Gas

28. Natural gas can be found in land and water

29. once again to burn it in electric companies to make steam to make turbines spin to make electricity for our homes.

30. But natural gas creates A LOT of pollution too.

31. Plus……it is very expensive to mine coal or to pump natural gas and petroleum oil from the ground.

32. Plus……we are running out of fossil fuels…
Plus……we are running out of fossil fuels….so we need to find other sources of energy.

33. non renewable resources.
And once we run out of fossil fuels, we can not get them back again ….
That is why they are called
non renewable resources.

34. Examples of Thermal heat using nonrenewable resources

36. Can you think of any new resources we can use for energy???

37. Alternative or Renewable Resources:
A resource we get from the earth, that we can run out of, but we can always get more of.
All Plants
All Animals
Soil

38. Soil is considered a renewable resource because when we use it, we take the minerals and vitamins out of it.

39. Once gone, we must replace those minerals and vitamins with fertilizer….or the plants we plant in that location will not grow strong. They will be weak and not produce much food. or

40. Can you name some more alternative or renewable resources?
Water
Air or wind
Sun’s energy
Biofuels
Biomass

41. Solar Energy comes from the sun natural resource
does NOT cause pollution
cheap…sun’s rays are free
solar panels can be expensive
inexhaustible resource (never used up)

42. Examples of Solar energy

43. Wind energy comes from the wind natural resource
does not cause pollution
cheap, wind is free
unreliable because sometimes the wind does not blow
wind farms becoming more popular
inexhaustible resource (never used up)

44. Examples of wind energy

45. Hydro Energy comes from moving water natural resource
does not cause pollution
cheap, water is free
unreliable because sometimes water is not available
inexhaustible resource (never used up)

46. Examples of hydro energy
long ago

47. Static Energy comes from friction manmade and natural
does not cause pollution
cheap, rubbing 2 surfaces together
not powerful enough for human to always use
inexhaustible resource (never used up)

48. Examples of Static Energy
sometimes called “static electricity”

49. Chemical Energy comes from batteries or combustion
manmade from natural resources
expensive to create
causes pollution sometimes
If using fossil fuels to make
researching new ways to make (wind, water)
both inexhaustible and nonrenewable depending on how its made

50. Examples of Chemical Energy

51. Batteries

52. (heat energy) Thermal Energy comes from the earth – fossil fuels
natural resource
decaying/decomposing plants and animals that died MILLIONS of years ago
causes pollution
expensive to get out of the earth
we will run out someday
nonrenewable resource (cannot be made)

53. All make electric energy
Hydro
Thermal
Solar
===Wind
