If clean water is scarce, is E85 a smart move?

I have not been a big fan of E85 or Flex-fuel vehicles. If you are a consumer that has such a vehicle, and regularly fills up with E85, I applaud you. However, I DO NOT applaud either GM or Ford for flex fuel technology. For many years this technology was simply used to violate CAFE, and I seriously doubt that a line of Flex Fuel Hummers or Tahoes is really going to help the world.

If GM was installing this inexpensive technology in all vehicles, especially their small cars, I'd be a little more supportive. Nonetheless, the potential of ethanol driven from cellulose is definitely worth further investigation.

Still, I do not believe ethanol offers anywhere near a complete solution to America's oil and/or fuel problems.

For decades, the idea of a war for clean water has been gaining steam and even the Pentagon has alluded to such a possibility. Further, a new report by the WWF environmental organization, for example, warns that many First World cities are already facing serious water shortages and the problem is only expected to get worse -much worse - and significant blame belongs to agriculture.

In the very near future, clean water could be worth more than oil, yet vast amounts of water will be required to irrigate and process our ethanol crops. And, what about the pollution from chemical fertilizers and other pesticides that will run off into our ever more important aquifers, lakes and rivers? Is it really worth it?

Certainly, ethanol is an interesting resource to explore, but if automotive companies only focus on fuel, rather than significantly better designed and significantly more fuel efficient vehicles, such as hybrid cars, ethanol addiction could easily lead to as many problems as foreign oil dependency.
