Car Forum / Toyota / Toyota Cars / October 2005And, from the same article:
So, it appears that those who say producing ethanol takes more energy than it returns only gave us half the story: Energy balance in the United States One study has concluded that the use of corn ethanol for fuel would have a negative net energy balance. Namely, the total energy needed to produce ethanol from grain — including fermentation, fertilizing, fuel for farm tractors, harvesting and transporting the grain, building and operating an ethanol plant, and the natural gas used to distill corn sugars into alcohol — exceeds the energy content of ethanol. However, all subsequent studies have concluded that ethanol production yields more energy than it consumes (most agree on a ratio of 1.34:1) This is remarkable when one considers that the two primary sources of fuel for transportation (diesel and gasoline) have a negative energy balance. Both consume about 20% more energy than they yield.

I had always heard the reason for NOT using Ethanol was that it took more energy to produce than was returned. i never heard this about fossil fuels. So, what's the holdup, then? > >> So, it appears that those who say producing ethanol takes more energy than > >> it returns only gave us half the story: [quoted text clipped - 7 lines] > >> ethanol plant, and the natural gas used to distill corn sugars into > >> alcohol — exceeds the energy content of ethanol.

There is no holdup. For the last year, we have been averaging the building of 2 ethanol plants a year. By my house, you can buy e-85 for about 70 cents less a gallon than regular gasoline. I just wish Toyota would pull their heads out of their a.ses and make their cars compatible with it. >>>> So, it appears that those who say producing ethanol takes more energy >>>> than [quoted text clipped - 33 lines] > I just wish Toyota would pull their heads out of their a.ses and make their > cars compatible with it. They do!

Why isn't the car compatible with it? Mods are needed to run ethanol? >>>>> So, it appears that those who say producing ethanol takes more energy >>>>> than [quoted text clipped - 44 lines] > > Why isn't the car compatible with it? Mods are needed to run ethanol? Yeah basically you need to get rid of anything in the fuel system that could possibly rust. You also have to program the computer to work with the higher octane and lower BTU of ethanol. A properly programmed car will only lose a little less MPG. >>>> So, it appears that those who say producing ethanol takes more energy >>>> than [quoted text clipped - 34 lines] > I just wish Toyota would pull their heads out of their a.ses and make > their cars compatible with it. I meant a month... not 2 new plants a year... but two new plants a month |
