From Environmental Technology

1. Some common disadvantages are:

OK

• ELECTRICITY- technology is limited, higher vehicle cost-lower vehicle range or performance, less convient refueling.
• ETHANOL- High fuel cost, somewhat lower vehicle range.
• METHANOL- Fuel could be imported, lower vehicle range.
• NATURAL GAS (METHANE)- Higher vehicle cost, lower vehicle range, and less convient refueling.
• PROPANE- cosst will rise with demand, limited supply, no energy security or trade balance benefits.
• REFORMULATED GASOLINE- higher fuel costs, few energy security or trade balance benefits.

2. It looks like- Very Low Emissions of ozone-forming hydrocarbons and toxics.

OK

3. I dont know what feasible means. But in my opinion the article does explain in great detail the advantages and disadvantages of using clean fuels. If a person was wanting to look into switching to clean fuels this article would more than likely give them a little of the information they need.

OK

4. Well here goes nothing:

OK

• 1) ELECTRICITY-N/A
• 2) NO.2 DIESEL-8 TO 15
• 3) BIODIESEL-25
• 4) ETHANOL AND METHANOL-100
• 5) LIQUIFIED PETROLEUM-104
• 6) LIQUIFIED NATURAL GAS AND COMPRESSED NATURAL GAS-120+
• 7) HYDROGEN-130+

5. Gasoline, No.2 Diesel, and BIO-Diesel. But gasoline is the main one.

OK

6. Energy content from least to greatest:

OK

• Electicity- N/A
• Hydrogen-3000 BTU
• CNG- 33000 BTU
• Methanol- 56000 BTU
• LNG- 73500 BTU
• Ethanol- 80000 BTU
• LPG- 84000 BTU
• Gasoline-109000 BTU
• Biodiesel-117000 BTU
• No.2 diesel-128000 BTU

7. Gasoline and Bio-Diesel seem to be the safest, after all we have used them for centurys.

OK

8. Well, I would say its true since it is on the U.S. Department of Energy official website. I dont think they would put somethign inaccurate and untrue on here. But i suppose if you wanted to find out wether its true or not you could write them and have them send you a copy or maybe send an email because most of the time you get a quicker response and its just as accurate as a piece of paper.

OK
