Some interesting highlights-
The pro's-
1. The U.S. Environmental Protection Agency has stringently tested it, and it can be used in any diesel engine with little or no modification to the engine or fuel system.
2. More than 200 biodiesel retail pumps have sprouted in the United States just in the last two years.
3. Biodiesel is touted as an environmentally friendlier alternative to petroleum diesel because it produces fewer emissions of greenhouse gases, soot, air toxics, carbon monoxide, and hydrocarbons compared to petroleum diesel.
The con's-
1. It can cost more than petroleum diesel. Consider this report from the Clean Cities Alternative Fuel Price Report: During the week of Dec. 8, 2003, both gasoline and petroleum diesel averaged $1.48 per gallon nationwide, while B20 (20 percent biodiesel) averaged $1.75.
2. Biodiesel has higher nitrogen oxide emissions, which are a contributor to smog and global warming.
The USEPA has this to say about nitrogen oxide emissions-
NOx
-is one of the main ingredients involved in the formation of ground-level ozone, which can trigger serious respiratory problems.
-reacts to form nitrate particles, acid aerosols, as well as NO2, which also cause respiratory problems.
-contributes to formation of acid rain.
-contributes to nutrient overload that deteriorates water quality.
-contributes to atmospheric particles, that cause visibility impairment most noticeable in national parks.
-reacts to form toxic chemicals.
-contributes to global warming.
Just when we start making progress, science throws a monkey wrench into
the wheels of the "discarded bicycle parts" the students are pedaling away on at Oberlin. Furthermore, it's hard to predict long term effects of invention on such a mass scale. Millions of engines burning biodiesel for hundreds of years could result in something worse than what we have now.
Don't you get. WE'RE DOOMED- DOOOOOOOOOOMMMMEEEDD!!!!!!!!!! I feel much better to get that off my chest though.
