Where does our electricity, heat, and fuel come from?
Nonrenewable ResourcesResources that are used up more quickly than they can naturally be replaced.
Renewable Resources Any natural resource that is recycled or replaced constantly by nature.
Renewable Resources -examples
U.S. Energy Use Totals 2009
Make electricity by turning a generator
Fossil Fuels the fuel is burned to boil water to make steamthe steam makes a turbine spin the spinning turbine turns a generator which produces electricity the electricity goes to the transformers to produce the correct voltage
Fossil Fuels (Oil, Coal, Natural Gas)Advantages Inexpensive Currently widely available Disadvantages Non-renewable Polluting Dangerous to mine (coal)
Nuclear Energy Advantages DisadvantagesLess polluting than fossil fuels Provides a great amount of energy inexpensively Disadvantages Non-renewable Radioactive waste (dangerous)
Solar Energy Advantages Disadvantages Non-polluting InexhaustibleExpensive technology Must have sunny area
Wind Energy Advantages Disadvantages Non-polluting RenewableVisual pollution (large windmills) Windy area needed
Hydroelectric Energy Advantages Disadvantages Non-polluting RenewableFlooding (destroys land/habitats) Destroys fish migration routes
Geothermal Energy Advantages Disadvantages Non-polluting InexhaustibleCostly to dig deep into Earth
Biomass –garbage, wood
Biomass Energy Advantages Disadvantages Quick to replace RenewableInexpensive Disadvantages Pollution produced when products are burnt
Without energy nothing happens.

Earth’s Natural Resources
Renewable and Non-renewable Energy Sources
Alternative Energy. Fossil Fuels Fossil fuels are a very efficient way to produce energy! However… – Burning Fossil fuels creates POLLUTION. – Coal mining.
Renewable and Nonrenewable Resources
