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
