Cuban sugar

We get most of our oil from the Middle East. That is really far away and the oil tankers that bring the oil back to the U.S. use a lot of gas, but we could use more ethanol. All imported oil and ethanol have a 2.5% fee. Duty fees are placed most of the time but why do we have to make a duty fee for something that will help the earth? For every gallon of ethanol that is imported to the U.S, 54 cents is charged. That is a lot money if millions of gallons are imported. The U.S. does not use much ethanol. The ethanol that is produced is also made of corn, which is a very expensive process. We could use sugar but we first have to find a lot of sugar. The answer is Cuba. 75% of Cuba's lands are sugar fields. That is a lot of sugar. Sugar is also coincidentally the cheapest method to make ethanol. Why don't we trade with Cuba then? We would only have to pay half of what we pay for gas now. I know a lot of people that need that. I just went to the gas station today, and a gallon is 4.07. I consider that a crisis. If we payed 2 dollars for a gallon of gas that does not hurt the environment as much as gas, that would be a miracle. The problem, though, is that the U.S. forbids any business with Cuba. That is a problem. We could be helping the earth, but instead, we are trying to fight communism. I think that this is a very bad decision by the government. We could have a better economy if gas was cheaper, but the government still does not change.
