1. Objective
Students will be able to explain the difference between renewable energy and non-renewable energy.
Students will be able to describe the difference between energy and work.

2. Energy vs. Work
What is the difference?

3. Energy
What is energy?
Energy is the ability to do work or cause change
Work: the use of force to move an object over a distance
W = F x d
Energy is measured in a unit called Joule (J)

4. Classifying Energy Forms of Energy Renewable/Non-renewable Energy
Mechanical
Thermal
Electromagnetic
Chemical
Nuclear
*Sound
*Electrical
Renewable/Non-renewable Energy
How we classify the source of the forms of energy that we use.

5. Renewable/Non-Renewable Energy
Energy obtained from resources that naturally replenish.
***Energy conversions can be traced back primarily to the sun.***
Earth and Moon also allow us to utilize energy.
Examples
Electromagnetic
Wind
Water
Geothermal
Biofuel
Non-Renewable
Energy obtained from a definite amount of material that comes from the ground in solid, liquid, or gas form.
Material is being consumed faster than it is being generated.
Examples:
Petroleum
Coal
Natural Gas
Nuclear *

6. Renewable Energy
Examples….

7. Solar Energy

8. Wind Energy (Mechanical)

9. Water Power (Mechanical)

10. Biofuel

11. Geothermal

12. Tides

13. Non-Renewable Energy
A nonrenewable resource is a natural resource that cannot be re-made or re-grown at a scale comparable to its consumption
Examples:
Nuclear *
Petroleum
Coal
Natural Gas

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

15. Fossil Fuels (Mechanical)
Include: coal, Petroleum, and natural gas are considered nonrenewable because they cannot be replenished in a short period of time.

18. What is the difference between coal and oil?
Coal – rock high in organic carbon, mainly from plant leaf material.
Oil – liquid hydrocarbon usually formed when a rock high in organic carbon is subjected to heat and pressure.
