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

5. NONRENEWABLE RESOURCES
Natural resource that cannot be
re-made or re-grown at the rate its being used (consumed)

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

7. FOSSIL FUELS Coal, oil, natural gas
Can’t be replenished in a short period of time

Renewable resources are natural resources that can be replenished in a short period of time.

14. SOLAR Energy from the sun SUN: Ultimate sources of energy on Earth
Advantage: No harmful emissions; “free” fuel”
Disadvantage: Need lots of land

15. GEOTHERMAL Energy from Earth’s heat.
Advantage: Doesn’t harm environment
Disadvantage: only available in some places

16. WIND Energy from the wind Advantage: potentially lots of energy
Disadvantage: lots of land used, not pretty

17. BIOMASS Energy from burning organic or living matter
Includes wood, dried field crops
Advantage: renewable
Disadvantage: air pollution from burning

Energy from the flow of water
Advantage: No burning; efficient
Disadvantage: flood habitat

19. ANIMAL & ANIMAL RESOURCES
Provides food and other products
Advantage: Renewable; can grow/produce more
Disadvantage: using too much; waste production

20. EFFICIENCY
Use of energy resources in the most productive ways

21. SUSTAINABILITY
Involves the global management of Earth’s natural resources to meet current and future needs WITHOUT causing environmental damage!
Protecting resources for future generations! 
