Fossil Fuels and Energy

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

COALCoal is used for:•Generating electricity •Old coal furnaces •Old locomotives•Power generators at some factories•Making steel

How can you conserve your use of coal in your daily life?

OilOil is used for: •Transportation fuels (gasoline)•Fuel oil for heating•Generating electricity •Road oil (tar/asphalt)

Petrochemicals are products made from fossil fuels, mainly

oil.

Where does natural gas come from?

⬜ 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?

Fossil Fuel Disadvantage

s

⬜ 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.

⬜ 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).

Electricity can be generated (made) by

renewable and nonrenewable

resources. Nonrenewable Energy Clip

What are the two most common renewable natural resources used to produce our electricity?

Renewable (Green Energy)

⬜ Wind power captures the energy in wind to produce electricity

Wind Turbines⬜ Turbines produce

California⬜ 5,000 turbines in

Solar Power⬜ harnesses the energy from the sun to produce electricity

GREEN Energy

Hydropower⬜ uses water to generate 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.

If we don’t start to generate more electricity from renewable

resources.

We will run out!
