Fossil Fuels vs. Alternative Energy
What is Fossil Fuel? Microorganisms are buried and decay Formed millions to hundreds of millions of years ago Supply is limited Burning produces carbon dioxide (CO 2 ) Contains other impurities that cause pollution
Examples of Fossil Fuels: Extreme emissions and pollution Petroleum (oil) Used to fuel vehicles Coal Powers electricity plants
More examples: Fossil Fuels considered to be less harmful than oil…. But still limited in supply. ► Natural Gas ► Propane Domestically abundant (in the USA) Fossil Fuel Dependence Fossil Fuel Dependence
Alternative Sources of Energy Options to replace fossil fuels Options to replace fossil fuels Solutions to solve environmental problems Solutions to solve environmental problems Reduce carbon emissions Reduce carbon emissions Lowers other greenhouse gases Lowers other greenhouse gases
Biomass energy sources Ethanol –Produced domestically –From corn or other crops –Produces lower greenhouse emissions Biodiesel –From vegetable or animal fats –Produces less pollution Alternative Fuels
Electricity as an Alternative Electric Motor Vehicles 75% of energy is converted to power 75% of energy is converted to power No tailpipe emissions No tailpipe emissions Domestic (self reliant) Domestic (self reliant) Stronger acceleration Stronger acceleration Less maintenance Less maintenance Electric Cars Electric Cars Internal Combustion Engine 15-20% of energy is converted to power Great emissions Political and Economic issues
