1. Fossil Fuels and Energy1

2. What is a Fossil Fuel?
A combustible (can catch on fire) material, found deep in the Earth’s crust that has been under pressure for millions of years.
There are 3 types of Fossil Fuels found in Earth’s crust.
Natural gas
Coal
Oil

3. COAL Coal is used for: Generating electricity Old coal furnaces
Old locomotives
Power generators at some factories
Making steal

5. How can you conserve your use of coal in your daily life?
Pair/share
How can you conserve your use of coal in your daily life?

6. Oil Oil is used for: Transportation fuels (gasoline)
Fuel oil for heating
Generating electricity
Road oil (tar/ashphalt)

7. Petrochemicals are products made from fossil fuels, mainly oil.
Man-made rubber
Plastics
cosmetics
WAX
medicine

8. Was it made by a fossil fuel???
paper
aluminum

sneakers
cotton

10. Where does natural gas come from?10

11. Found deepest in Earth’s crust Found as a gas
Natural Gas
Oldest fossil fuel
Found deepest in Earth’s crust
Found as a gas
Made from decayed animals
Gas companies add a sulfur smell to the fluid.
Why is this important? 11

12. Natural Gas Household Uses
Heat water – hot water heaters
Heat homes – furnaces
Cooking – stoves
Drying clothes – clothes dryers
Natural Gas Household Uses 12

13. Pair/Share What are 4 ways we use Natural Gas in the household.
What are 3 ways you can conserve Natural Gas in your home?
Heat water – hot water heaters
Heat homes – furnaces
Cooking – stoves
Drying clothes – clothes dryers

14. Fossil Fuel Disadvantages
Have a limited supply
(It takes a long time to create. So once we use it all up it is gone!)
When burning any fossil fuel it puts greenhouse gases such as CO2 and methane into the atmosphere.
(Increased levels of greenhouse gasses causes Global Warming. )

15. What is Global Warming? (Climate Change)
Global Warming is the gradual increase of earth’s temperature.
Greenhouse gasses like CO2 and methane enters the atmosphere and traps heat around the earth.
What is Global Warming?
(Climate Change)

18. Why is Global Warming bad?
video and info site
An increase in Earth’s temperature can cause the polar icecaps to melt.
Changes weather patterns: Floods, hurricanes, tornados, effects some biotic factors natural timing.

19. How to Conserve 1. Take shorter showers (less heat is used)
2. Install High Efficiency Fixtures in your home
3. Heat your home only when necessary (keep it at about 68 °F)
4. Switch to electric appliances
5. Only wash with full loads (laundry and dishes)

20. Energy

21. What is Energy? Energy is the ability to do work or to produce change.
We use energy to listen to music, watch TV, play video games, even our bodies use energy.

22. Almost everything requires energy
Our bodies need energy to do things like move, digest food, regulate our body temperature.
Plants need energy from the sun to make their own food during photosynthesis.
Volcanoes need energy to erupt.

23. Different Types of Energy
Potential Energy
Kinetic Energy
Chemical Energy
Elastic Energy
Nuclear Energy
Thermal Energy
Electric Energy = Electricity

24. Electricity
Electricity is a type of energy you use to power appliances that plug into the wall or attached to a switch.
Electricity consumption is measured in Kilowatt-Hour (kWh).

25. Nonrenewable Energy Clip Renewable Energy Clip
Electricity can be generated (made) by renewable and nonrenewable resources.
Nonrenewable Energy Clip Renewable Energy Clip

26. Oil
Coal
Nuclear
Natural Gas

27. Non Renewable Energy Resource
57% of your electricity comes from coal and natural gas!
Remember to turn out the lights!!!

28. Energy Resources GREEN Energy 7% 4% 4%

GREEN Energy 7%
Solar Energy 4% 4%
Biomass Energy
Hydropower Energy
What are the two most common renewable natural resources used to produce our electricity?
41%
44%
Wind Energy
Geothermal Energy

29. Renewable (Green Energy)
Wind power
captures the energy in wind to produce electricity

30. Wind Turbines Turbines produce electricity.
16,000 turbines in California
5,000 turbines in Tahachapi; 75miles north of Los Angeles

31. Solar Power GREEN Energy
harnesses the energy from the sun to produce electricity
GREEN Energy

32. uses water to generate electricity
Hydropower
uses water to generate electricity

33. Uses heat from the earth’s core to produce electricity.
Geothermal
Uses heat from the earth’s core to produce electricity.

35. Biomass
Is organic material that is burned to heat water in boilers, which produce steam and spin a turbine to create electricity.

37. Are you shocked that 80% of our electricity comes from Non-renewable resources?
The state of California mandates that by 2020, 30% of all electricity must come from renewable resources.
Problems with Our Dependence on Fossil Fuel
Is this Really Enough?

39. 5% of the world’s population lives in the USA but the USA uses 26% of the world’s energy.

40. If we don’t start to generate more electricity from renewable resources. We will run out!

41. How do we reduce  the use of non-renewable resources?

42. Think, pair, share How can we reduce the use of
non-renewable resources?

43. Think, pair, share
What can YOU do to conserve energy??
