- Before you make any decisions based on the cleanliness of ethanol as
- motor fuel, be sure to have a look at the lifetime energy costs of the
- technology. In the midwest US, fuel-ethanol comes from fermenting corn
- syrup (same stuff as they put in Coca-Cola over here). Corn takes plenty
- of energy to grow, transport to the fermentation plant(no pipelines, it
- goes by truck and train), and plenty of energy for cooking, fermentation,
- and distillation. And don't forget that modern mass farming methods
- are depleting and eroding the soil with every season, and introducing a
- lot of nasty chemicals into the water table.
-
- Like most things, the use of ethanol in the US is wrapped up in politics,
- with the government paying a subsidy to farmers for growing "fuel crops",
- and subsidies to the processors, making them rich, and artificially
- lowering the lifetime monetary cost of the fuel below that which would
- be reflected by the production process. Then they say it's "cleaner
- burning".
-
- I'm not saying ethanol's actually any dirtier in the long run than
- Dino-fuel, but it's not a panacea, nor is it a truly renewable
- resource.
