Hemp fuel could be used in trucking, trains and power plants. That would free up enough petroleum to lower the price of gasoline considerably. Here in the US, we pump more oil from our own wells than we import from the mideast. Hemp would allow us to break free from the mideast mess.
What are the complication factors preventing us from doing that?
How about this? If Canada has allowed cultivation of hemp for commercial purposes, they could process it into fuel and sell it to us.
