Alternative Energy Transportation Transportation Mr. O’Rourke
Definition A source of energy for transportation that utilizes something other than fossil fuel for power.
Alternative Energy Benefits Low/no environmental impact Reduces dependency of foreign oil Efficient $$$
Biofuel Fuel derived from recently living biological matter (plants). Fossil fuel is derived from long dead biological matter.
Compressed Air Used stored compressed air to power a motor Can be used in addition to electric/solar/gasoline etc. (hybrid)
Types of Biofuels Vegetable Oil- can be used interchangeably with diesel on old engines or can be converted to biodiesel for new ones. Biodiesel- produced from oils or fats and is similar to diesel. Bioalcohol- ethanol, propanol and butanol (all biologically produced alcohols). Biogas- contains methane (landfill gas)
Electric Cars Automobiles that use an on-board rechargeable energy storage systems. Produce no exhaust fumes and minimal pollution Many are capable of accelerating faster than conventional automobiles.
Hydrogen Cars Use hydrogen for fuel Hydrogen is burned through combustion Hydrogen is converted in a fuel cell –Reacted with oxygen to produce water and electricity
Hybrid Automobiles An automobile that uses two or more distinct power sources for propulsion. Most common is internal combustion engine/electric motor. Nearly every large car manufacturer now produces one or more hybrid automobile.
Solar Vehicles Similar to an electric car. PV cells convert sun’s energy into electrical energy. Not as practical for day to day transportation as other alternative energy vehicles.
Any Others? Any other types of alternative energy vehicles you can think of???
