Read Clean fuels: an overview, then answer the following questions.

1) What is a common disadvantage of switching to clean fuels for vehicles?

  It would be hard to replace all the current forms of fuel because of their mass establishment. The main reason for this is the cost it would take. Plus the technology right now is iffy. They are slow. 

2) What is the most overwhelming common advantage of switching to clean fuels?

  Up to 90% lower in toxins and ozone-forming hydrocarbons which is expected to reduce emissions up to 25% over today's gasoline.

3) Does this article really answer whether clean fuels are feasible?

  I think it does, yes.

Read about alternative fuels at the AFDC. Pay close attention to the section Compare Alternative Fuel Properties, then answer the following questions:

4) List the fuels on the Comparison chart by octane rating, from lowest to highest:

  Biodiesel 25, Methanol (M85) 100, Ethanol (E85) 100, Liquified Petroleum Gas (LPG) 104, Liquified Natural Gas (LNG) 120+, Compressed Natural Gas (CNG) 120+, and Hydrogen 130+.

5) Which alternative fuel has the most diversity to date for types of vehicles?

  Biodiesel

6) Rank the all the fuels on the chart by their energy content from highest to lowest:

  1. Biodiesel 2.LPG 3.Ethanol (E85) 4.LNG 5.Methanol (M85) 6.CNG 7.Hydrogen

7) Gaging by the chart, what seems to be the safest fuel?

  Biodiesel maybe Hydrogen I cant really tell from the chart.

8) Do you have any way of gaging whether this chart was accurate or not? How would you go about finding out if it is true or not?

  Yes because it has a link to the EPAct web site and also others. I would surf the web looking for ligitament sites to find info.
