2. Natural Resources

3. What is a natural resource? What are the 2 types of natural resources?
HMMMM....
What is a natural resource?
What are the 2 types of natural resources?

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

5. 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!

6. Pros and Cons of Nuclear Energy
Low greenhouse gas levels
Large power-generating capacity
Very little air pollution because it is not burned
Cons:
Non-renewable
High construction cost
High risks in an accident
Not easy or safe to ship

7. Fossil Fuels
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.

8. HOW IS COAL MADE ???

9. HOW ARE OIL AND GAS MADE ???

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

11. Pros and Cons of Fossil Fuels
Considered to be highly efficient
Widely used
Delivery system already exists
Cons:
Non-renewable
Emits pollutants into the air when burned
Explosive and potentially dangerous

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

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

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

15. Pros and Cons of Solar Energy
Renewable
Non-polluting
Low maintenance
Cons:
Intermittent
Expensive
Produce low grade energy

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

17. Pros and Cons of Geothermal Energy
Renewable
Clean
Stable
Cons:
Initial cost is very high
Only reasonable to extract it in certain places
Generates very little energy compared to other sources

18. Why is energy from the wind renewable?

19. Pros and Cons of Wind Energy
Clean Energy
Renewable
Power essentially free once infrastructure is paid for
Cons:
Inconsistent
Wind from turbines and land needed make them only good in rural areas
Wildlife fatalities

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

21. Pros and Cons of Biomass Energy
Renewable
Widely Available
Low cost
Cons:
Some fuels are seasonal
Energy intensive to produce
May compete directly with food production (corn, soy)

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

23. Pros and Cons of Hydroelectric Energy
Little to no pollution
Renewable
Little cost after building dam
Cons:
Building the power station is VERY expensive
Flooding disrupts the ecosystem
Dams prevent fish from swimming upstream

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

25. Write this in the bottom of your notes:
Renewable resources can become non-renewable if we overuse them
