EdWort said:I don't understand where the potential is. It uses more fuel to produce than it makes (net fuel loss for each gallon), it makes more pollution, it is less efficient which means you must use more to go the same distance, it wastes tons of water (literally), and it is driving up the prices of food and beer.
I think the point of the OP is that ethanol production is in it's infancy. As it matures, breakthroughs will happen and it will become a much more efficient fuel to produce. Just like when oil, coal and natural gas were in their infancies, it took much more to labor/fuel to produce a gal/pound that was actually extracted. Given time for infrastructure and advancements in production, ethanol could be a very viable source.
Ethanol, however, is not at all responsible for the higher prices in food and/or beer. You want to blame something, blame the soaring costs of oil. Ethanol production last year was the same as it's been in the past five years. It's the costs to produce, package (in plastic made from oil) and ship (using gas and diesel) food products that is driving up the costs of food. Another big reason for the skyrocketing costs of food is the declining value of the dollar. Products imported are no longer as cheap as they used to be and those costs are passed on to the consumer.
