hmmm, I wonder if these scientists are the same guys who figured out Global Cooling, or Warming...maybe? Oh, heck - let's just call whatever it is Climate Change, yeah - that's it.....
But I digress, EVERYTHING I've read so far has shown that Ethanol from ground to exaust pipe
reduces emissions compared to gasoline from well to exaust pipe. But most of that reduction is taking into account the C02 emissions that would have occured due to these plants decaying in the landfils after we've eaten them, or just the waste siting on the ground anyways. However, I will scede that Corn Ethanol, though still advantageous...isn't great. It's reduction is only like...20%?
After reading up and learning about this stuff, the way I like to describe it, is that gasoline is pumping out Mother Earth's crap, and reintroducing it into the atmosphere...it would have stayed where it was if it wasn't for us. Plants, however, would always keep decaying, making emissions by burning it instead of letting it decay doesn't make much of a difference.
Plus, how can ANY study show anything like that 30 years into the future? By using a very narrow view of everything staying the same as it is now. Efficiency will change; and by that time, there's been talk of growing the 1.5 - 2x the amount of corn/switchgrass in the same landspace....
And if anybody even suggests that we cut down rainforests for biofuel, me and Billions of other people will personally wring their necks. Wrong. Ain't gonna happen.
It seems to me, I'm no physcic and I'd hate to be wrong, but it seems this guy doesn't like Ethanol very much...and has his own gains to be made off of other energy sources.......
