2  Renewable Energy from the Sun Wind Water Wood Fruits and Vegetables Meat from animals  Nonrenewable Fossil Fuels Coal Petroleum (oil, gasoline) Natural Gas Rocks Minerals Metals Plastics

3 Where do humans get useful energy? Energy Resources – natural resources that humans use to produce energy.

4 Remember…  There are many types of renewable and nonrenewable energy resources and all of the energy released from these resources ultimately comes from the sun.

5 Where do humans get useful energy?  The energy resources on which humans currently depend the most are fossil fuels.

6 What are fossil fuels? Fossil Fuels – nonrenewable energy resources that form in the Earth’s crust over millions of years from the buried remains of once-living organisms.

7 How do fossil fuels work?  Energy is released from fossil fuels when they are burned.  There are many types of fossil fuels, which exist as liquids, gases, and solids, and humans use a variety of methods to obtain and process them which can sometimes have negative effects on the environment.

10 Liquid Fossil Fuels Petroleum – crude oil, an oily mixture of flammable organic compounds from which liquid fossil fuels and other products, such as asphalt, are separated.

11 What is separated from petroleum?  Gasoline  Jet Fuel  Kerosene  Diesel Fuel  Fuel Oil

12 Gaseous Fossil Fuels Natural Gas – a gaseous fossil fuel. Most natural gas is used for heating and for generating electricity.

13 Components of Natural Gas  Methane Fuel  Butane Fuel for camp stoves  Propane Heating fuel and as a cooking fuel

14 Solid Fossil Fuels Coal – a solid fossil fuel formed underground from buried, decomposed plant material.

15 Importance of Coal  Coal, the only fossil fuel that is a rock, was once the leading source of energy in the United States.  People burned coal for heating and transportation.

16 How do fossil fuels form?  All fossil fuels form from the buried remains of ancient organisms.

17 How does coal form?  Coal forms underground over millions of years from decayed swamp plants.

18  The higher the carbon content, the cleaner the material burns.

19 OUT: What would happen if we used up all of the Earth’s fossil fuels?
