Illinois study shows perennial biofuels give off less nitrogen
|
Perennial crops like the tallgrass miscanthus can be turned into ethanol like corn, but give off less nitrogen into the atmosphere, according to a University of Illinois study. Limiting nitrogen is important because it can produce nitrous oxide, a greenhouse gas that furthers global warming. And nitrate can contaminate drinking sources and leach into lakes where it contributes to lethal dead zones for fish life. Ethanol is added to gasoline to reduce dependence on the fossil fuels that contribute to global warming. But it’s counterproductive to produce ethanol in a way that makes yet another powerful greenhouse gas – nitrous oxide.
