Here's a lesson in legislation over-estimating reality. In 1992, Congress passed an aggressive energy bill requiring that 30 percent of the fuel powering U.S. cars come from sources other than gasoline. Sounds great, but the problem is that we're no where near meeting that deadline. Due to a recent environmental group lawsuit, the Department of Energy was required to develop a revised goal. Last Tuesday, the DOE proposed that goal be pushed back 20 years and be set at 2030.
