Fossil Fuels. Mrs. Hartman. Fossil Fuels. Most of the energy we use comes from fossil fuels Definition: a nonrenewable energy source formed from the remains of plants and animals that lived long ago. Examples: petroleum, coal, natural gas. 3 types of fossil fuels.
2. Gas: Natural Gas: located under the surface of earth; used for heating and generating electrical energy
3. Solid: Coal: formed underground from partially decomposed plant material.
Used to be used to power trains.
We cut down on our use of coal because it pollutes the air (now we use oil because it’s cleaner)
Power plants still use coal to generate electrical energy.
