Are Biofuels Really The Answer?
This month’s issue of
Smithsonian magazine has an article about biofuels and asks the question; "Is there actually a positive environmental impact to using biofuels?" After reading the article, it looks like making biofuels isn’t a problem as long as we begin using a cellulosic technology. Unfortunately, there are some major political lobbyists who may have a problem with this.
On the environmental side of things, there is the issue of land usage, the drawback to corn based ethanol is that it takes one acre to produce 60 gallons. Cellulose based ethanol is better, but you still need to more land to produce only a small fraction of the capacity needed by the US alone.
There is also the fact that burning biofuels still produces carbon dioxide. The use of biofuels doesn’t produce as much carbon dioxide as gasoline, but fuel based (usually coal) heat is also still needed in the biofuel production process.
