1. Resources

2. What is a resource?
Supplies used to meet some kind of need. (ex. A pencil is a resource that allows you to write and take notes in class.)

3. Natural Resources Resources found on the planet that occur in nature.
Serve a variety of needs such as food or shelter
One of the greatest needs is energy

4. Renewable vs Nonrenewable
What is the difference between these two types of resources?

5. NONRENEWABLE RESOURCES
A nonrenewable resource is a natural resource that cannot be re-made or re-grown within the span of one human life.

6. 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!

7. 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.

8. HOW IS COAL MADE ???

9. HOW ARE OIL AND GAS MADE ???

10. Non-renewable Pros
Most nonrenewable sources of energy are easy to transport from one area to another. For example petroleum oils which can be transported via pipes.
Cost of producing nonrenewable energy is low since they are naturally available. Furthermore they are cheap to transform from one form of energy to another.
Most of this energy sources are abundantly available in different areas. Their availability is not affected by climatic condition
For Notes:
Easy to transport
Very low cost
Not affected by climate or area.

11. Non-renewable Cons
Produce harmful green house gases which contribute global warming. Coal once burnt produces carbon dioxide harmful to the environment.
Once they are depleted they cannot be replaced making them expensive to obtain
For Notes:
Cause pollution to the environment
Cannot be reproduced (they will run out eventually)

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

13. It will never run out as long as the sun still exists
SOLAR
Energy from the sun.
It will never run out as long as the sun still exists

14. Energy from Earth’s heat.
GEOTHERMAL
Energy from Earth’s heat.
It can be difficult to harvest, but it provides and endless supply of energy

15. WIND Energy from the wind.
Can be unreliable in certain areas (if its not windy then there is no power)

16. WATER or HYDROELECTRIC
Energy from the flow of water.
Depends upon finding a river or other water source sufficient to collect energy.

17. Soil
Soil is a combination of dirt and dead plants and animals. It forms a very thin layer on the surface of the planet. It allows us to grow food. Though soil does deplete (run out) depending on the environment it can be fairly simple to return nutrients to the soil so you can continue to use it.

18. Renewable Pros
Renewable sources of energy are renewable and easily regenerated. This is unlike fossil fuels which are perishable once used.
Renewable source of energy such as solar produce clean energy that does not pollute the environment. This is because no burning is required during usage of the energy.
Most importantly, renewable energy are available everywhere throughout the world thus there is no chance of the sources becoming depleted in future. For example, solar energy is everywhere as the sun will always be there every day.
Maintenance cost needed to install and use the renewable energy is relatively cheap. Solar energy can be trapped easily and used for domestic needs.
For Notes:
Constantly Regenerate (will never run out)
Does not pollute the environment
Available all over the planet
Maintenance cost is low

19. Renewable Cons
Difficult to produce the energy quantity that is equivalent to that produced by nonrenewable fuels
Technology required to trap renewable energy is costly. Setting of dams requires high initial capital to construct and maintain
Most renewable sources of energy are affected by weather thus reducing their reliability. For example, hydro generators need constant rainfall that will overflow the dams, wind turbines only rotate if there is wind of a given speed.
For Notes:
Difficult to produce enough energy to meet demand
It costs a very large amount to set up something to trap and convert the energy
Energy is subject to the weather and environment meaning that not every type of energy will be available.
