A combustible (can catch on fire) material
Found deep in the Earth’s crust
Millions of years old
Made of decomposed plants or animals that died Millions of years ago.
Made by pressurizing and heating decomposed plant and animal material.
Natural 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.

Cleaner burning than other fossil fuels, like Cleaner burning than other fossil fuels, like coal and oil. By using Natural Gas, the US coal and oil. By using Natural Gas, the US has reduced Carbon Emissions (pollution) has reduced Carbon Emissions (pollution) into the air by 7.7%= 84 Billion cars (since into the air by 7.7%= 84 Billion cars (since 2006)2006)

(It takes a long time to create. So once we use it all up it is gone!)
When burning any fossil fuel it puts CO2 into the atmosphere.
(Increased levels of CO2 causes Global Warming. )
If we continue to use Natural gas at the rate we are using it, we will run out!

Global Warming is Global Warming is the gradual the gradual increase of earth’s increase of earth’s temperature. temperature.
Greenhouse gasses Greenhouse gasses like CO2 enters the like CO2 enters the atmosphere and atmosphere and traps heat around traps heat around the earth. the earth.
Why is Global Warming bad?

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.
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 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.
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.
Potential Energy Kinetic Energy Chemical Energy Elastic Energy Nuclear Energy Thermal Energy
Electric Energy = 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).

What are the two most common renewable natural resources used to produce our electricity?
Wind power
captures the energy in wind to produce electricity
Have been around since the 7th century
Used to grind and pump in a circular motion.
Turbines produce electricity.
16,000 turbines in California

uses water to generate electricity
Uses heat from the earth’s core to produce electricity.
Is organic material that is burned to heat water in boilers, which produce steam and spin a turbine to create electricity.
The state of California mandates that by 2020, 30% of all electricity must come from renewable resources.
