1. Alternative Renewables

2. Biofuels Plant or animal material 3 types – Biomass Wood, yard waste Methane from landfills, feedlots Burned and used to create steam  electricity – Biodiesel Oils or algae Byproduct: Glycerin Pure or mixed Energy Information Decreased emissions Storage

3. Ethanol Corn or sugar cane Mixed with gasoline Byproducts used as feed Energy Information – In vs Out – Final product Decreased emissions

4. Biofuels Advantages EES 1 st EES 4 th EES 6 th EES 7 th Disadvantages

5. Geothermal Uses naturally hot air underground Pump air to surface Requires energy Remove toxins Spins turbines, turns generators Cooler air sinks Process repeated Reverse – air conditioning

6. Hydrogen Separated from water Using lots of electricity Burned for energy Cars Clean Energy Information
