This letter was written as a follow up to the oral testimony by Amory Lovins to the Congressional Committee on Commerce, Science, and Transportation. The letter outlines measures that would have a significant effect on U.S. demand for conventional petroleum. Lovins’ proposed measures would add up to between a 5% and 9% reduction in the U.S. demand for conventional crude oil, and do so with little or no interruption of our way or quality of life. Lovins’ measures target consumption by eliminating gas and diesel use by changing policy to make vehicle trips more efficient. The recommendation letter also includes proposed measures to increase the supply of energy.
