2. Our Planet’s Energy Resources
Energy- The ability to do work or cause a change
Potential Energy- Stored Energy
Ex: Chemical, Nuclear, Gravitational, Mechanical
Kinetic Energy- Energy in Motion
Ex: Electric, Radiant, Thermal, Mechanical
Law of Conservation of Energy-
Energy can be converted from one form to another but it cannot be created or destroyed

3. ENERGY CONVERSIONS Identify the initial and final forms of energy
Potential-
Motion, chemical, nuclear, gravitational
Kinetic-
Motion, electrical, radiant, thermal
Example 1: Ice Cream to Bicycling
Example 2: Sunlight to Photosynthesis
Example 3: Gasoline to School Bus

4. Energy Resources

5. Sources of Energy: Renewable vs Nonrenewable energy
Biomass
Hydropower
Geothermal
Wind
Solar
Nonrenewable:
Coal
Natural Gas
Petroleum
Nuclear
Transuranium elements

6. Fossil Fuels
Petroleum (Crude oil)- A liquid fuel made from the remains of dead sea organisms
Hydrocarbons- The major components of petroleum. These compounds contain a tremendous amount of energy and can be easily manipulated to form many products.

7. Petroleum Products FUELS:
Fractional Distillation- Separating a liquid mixture by different boiling points
FUELS:
METHANE
PETROLEUM
GASOLINE
KEROSENE
DIESEL
JET FUEL
HEATING OIL.

8. Other Petroleum Products:
Fertilizers
Pesticides
Solvents
Fabrics
Construction materials
Household Chemicals

9. How Much Petroleum Remains?
At this pace, we have almost 37 years of oil remaining

10. Other Fossil Fuels
Coal- Prehistoric plants buried in swamps transformed by heat and pressure deep within the Earth. It is used most commonly in power plants.
4 types:
Lignite (From Peat)
Subbituminous
Bituminous
Anthracite
Natural Gas- Composed primarily of methane (CH4) A waste product created when petroleum is formed. It is typically a very clean burning fuel used in homes for heating and cooking.

11. The Source of All Energy On Earth
The Sun-
Our star which uses nuclear energy to produce thermal and radiant energy.
Gives energy for photosynthesis by plants and algae.
Autotrophs provide energy at the base of all food webs.
Over millions of years, chemical energy in living organisms form fossil fuels.

12. Creating Electricity
Fossil Fuels are burned to create steam which is forced through pipes to turn turbines. The turbines turn the wires within a generator creating electric current. The current comes to your homes through lines on towers and into wall sockets.

13. The Problems with Fossil Fuels
Sulfuric and Nitrogen Compounds which cause acid precipitation. This harms plants, animals, humans,and destroys buildings and monuments.
Carbon dioxide which is a greenhouse gas. These gasses trap solar energy, increasing the average global temperature.

14. The Problem with Nuclear Energy
Nuclear- supply more electricity than oil, natural gas, and hydropower. But there are major risks involved including nuclear safety, nuclear waste, and nuclear weapons.

15. Alternative Sources of Energy
All are viable sources of energy but there are problems:
1) Costs
Technology, Infrastructure, training,
2) Consumer Confidence
Not the norm, What it is? Why isn’t everyone using it?
3) Unforeseen circumstances
Natural disasters or changes
4) Lack of Reliability
Enough wind, sunlight, water in certain areas of the world
5) Cultures
Not used now, why begin or we have enough of other sources

16. WHAT DIRECTION DO YOU THINK WE’RE HEADING IN?
Keep this in mind as we take a look at some of the energy sources that we rely in the upcoming days.
