The energy problem

  1. 1. The Energy Problem:Alternatives for Fuel Powered Vehicles Nathalie Beneche
  2. 2. How much fuel does the US useevery year?One of the biggest questions that is asked about the United States and its oil usage is: is the US addicted to gasoline? And the fact that the US holds 4.5% of the Earth’s population, yet consumes over 20% of the world’s energy, makes the question seem to be a fact.The US consumes 21 million barrels of oil each day.It also consumes more gasoline than South America, Europe, Africa, and Asia combined.
  3. 3. What can be used instead ofgasoline to power cars?Ethanol is a popular alternative to fueling vehicles. It is an alcohol-based fuel made by fermenting and distilling starch crops, like corn and sugar cane. It produces less greenhouse gases and emissions.E10 means there is 10% ethanol and 90% gasoline.E85 is also used and it contains 85% ethanol and 15% gasoline. This can be used in flexible fuel vehicles.
  4. 4. Biodiesel, Another Option Biodiesel is a renewable, clean-burning diesel replacement made from vegetable oils and animal fats. It produces less air pollutants than the petroleum based diesel and cuts greenhouse gas emissions by over 50%. And therefore, reduces our need on foreign petroleum. Biodiesel can be blended with petroleum diesel and can be therefore be used in compression- ignition engines.
  5. 5. Biofuel and EthanolBiofuel differs from Ethanol primarily because ethanol is used to replace gasoline powered cars and biofuel is used to replace diesel.Also Ethanol is made primarily from corn and Biofuel is made from a variety of different materials.
  6. 6. Natural Gas, A Third OptionNatural Gas is a hydrocarbon gas mixture of methane and up to 90% of other hydrocarbon gases, usually ethane, and some small amounts of carbon dioxide
  7. 7. There are other ways to cut the use of gasoline besides just replacing it…
  8. 8. Hydrogen Vehicles Hydrogen vehicles  The power plants of include space rockets, these cars convert the automobiles and other chemical energy of transportation vehicles. hydrogen to mechanical Hydrogen fuel is an energy either by burning energy carrier and can hydro in an internal be produced from fossil fuels such as coal, combustion engine or by nuclear power or reacting hydrogen with hydropower which is a oxygen in a fuel cell to renewable resource. run electric motors.
  9. 9. Electric CarsElectric cars are powered by an electric motor instead of gasoline.Electric cars were fast, clean, quiet, and loved by those who owned it when it first appeared in
  10. 10. Comparison of Electric Car to Hybrid Car
