Fossil Fuels and Energy 1

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

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

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?

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

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

Was it made by a fossil fuel??? paper aluminum electricity sneakers cotton 6. nylon stockings 7. fertilizer 8. crayons 9. spoon 10. candles NO YES NO YES YES YES YES YES NO YES

Where does natural gas come from? 10

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

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

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

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. )

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)

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.

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)

Energy

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.

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.

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

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).

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

Oil Coal Nuclear Natural Gas

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

Energy Resources GREEN Energy 7% 4% 4% Southern California’s Edison’s renewable energy breakdown. % of total renewable energy produced. 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

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

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

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

uses water to generate electricity Hydropower uses water to generate electricity

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

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

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?

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

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