Bio-fuels are in the news again. Here are two concrete facts that disprove the ethanol claims;
1) If ethanol yielded more energy than is required to produce it, everyone would be doing it & getting rich in the process. Obviously if one BTU of energy produced ethanol with two BTU of energy, the chain reaction would see the world swimming in cheap energy before you could say Barack Obama 3 times. Even if the increase was very small, the end result would be the same.
2) Ethanol usage is forced on us and production is subsidized by governments all over the world. If ethanol is cheaper than gasoline, why does it have to be subsidized & why are laws required to force us to use it? You can see that if ethanol production was really competitive with gasoline, production plants would be springing up all over the place. In fact, oil producers PAY taxes and ethanol producers RECEIVE tax dollars.
Using common sense is a far more effective way to gauge the world than relying on every self-serving "scientific study" that rolls across the landscape.
