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.
Why is this important?

(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. )

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.
![Page 22: Natural Gas (fossil fuel). Where does natural gas come from?](https://reader035.vdocuments.us/reader035/viewer/2022081418/56649eb45503460f94bbc3f9/html5/thumbnails/22.jpg)
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.

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).
