all in an effort to keep america from using its own natural resources and drilling for the tons of oil we have available to us in our own country.
All plant life is rich in Nitrogen. So all bio fuels that are burned have a chemical reaction that consist of many things such as H20, CO, CO2, NO2. For example, Natural gas will put out less CO2 than coal; however natural gas puts out much more NO2 than coal.
This is the first I heard NO2 was a greenhouse gas. I thought the concern was NO3, which is theorized to be a carcinogen. That is why compression ratios were turned down in gas engines in the 1970's and diesel engines recently have had exhaust modification to reduce NO3.
However, personally, I do not trust any of these studies and can't keep up with the new dooms day theory of the day. Oh, and ethanol is a boondoggle
