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 fission uses uranium to create energy.
NUCLEAR ENERGY
Nuclear fission uses uranium to create energy.
Nuclear energy is a nonrenewable resource because once the uranium is used, it is gone!

5. Fossil Fuels
Coal, Petroleum/Oil, and Natural gas are considered nonrenewable because they can not be replenished in a short period of time. These are called fossil fuels.

6. HOW IS COAL MADE ???

7. HOW ARE OIL AND GAS MADE ???

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

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

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

11. Why is energy from the sun renewable?
SOLAR
Energy from the sun.
Why is energy from the sun renewable?

12. SOLAR unable to be used up
Sun – light from the sun supports all the life on Earth as we know it. Considered inexhaustible. (at least for the next 5 billion years)
Inexhaustible means...
unable to be
used up

13. GEOTHERMAL Energy from Earth’s heat.
Why is energy from the heat of the Earth renewable?

14. GEOTHERMAL
Geothermal energy – the heat generated deep within the Earth.
Fueled by the decay of radioactive elements. Used to heat water.

15. Why is energy from the wind renewable?

16. WIND
Wind – caused by the uneven heating of the Earth. Not only renewable but inexhaustible.
(unable to be
used up)

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

18. BIOMASS FUELS
Biomass fuels – are organic matter (wood, plants, animal residues, etc…) that contain stored solar energy.
**Used to supply energy to 15% of the world’s supply.

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

20. WATER Water – constantly renewed/replenished by the water cycle.
However, freshwater resources are somewhat limited.
The use and quality of water must be carefully monitored to ensure future use.
