1. Chapter 5 Energy Resources

2. 5.1 Notes Fossil Fuels
energy resources - natural resources that we use for energy (wind/water/fossil fuels)
fossil fuels - nonrenewable energy resources that are found in the Earth’s crust that come from dead plants and animals (can be a liquid, solid, or gas)
liquid fossil fuels = petroleum (crude oil)
solid fossil fuels = coal (used in a barbeque) – changed into heat
gaseous fossil fuels = natural gas (stove, heater) – changed into heat (produces less pollution than coal)

3. 5.1 Notes Fossil Fuels Problems with using fossil fuels for energy:
Pollution (air, land, & water)
Increasing carbon dioxide in atmosphere, which is contributing to global warming
acid precipitation – rain or snow that has a high acid content due to air pollution
smog – a fog that exists when sunlight touches air pollution

4. 5.2 Notes Fossil Fuels
What can you do to help solve the problem of fossil fuels? (please be practical):
Travel by bus
Carpool
Walk, ride a bike

5. 5.3 Notes Alternative Resources
7 types of alternative resources that we use for energy:
nuclear energy - energy that comes from the nuclei of an atom
solar energy – energy from the sun (expensive), uses solar panels and solar cells
wind energy – energy that comes from wind (windmills)
hydroelectric energy – energy produced by falling water (water wheels, dams)

6. 5.3 Notes Alternative Resources
5. biomass - dung that contains stored energy
gasohol - alcohol and gasoline mixed together creates energy
geothermal energy - energy produced by heat in the Earth’s crust
