Hybrids have saved 230 million gallons of gas so far

Still just a drop in the gas bucket

Since hybrid vehicles first hit the road, they have saved 230 million gallons of gas according to the U.S. Department of Energy's National Renewable Energy Laboratory (NREL).

Unfortunately, that amount of fuel saved doesn't even equal a full day's worth of gasoline consumption. Nonetheless, NREL believes hybrids can have a huge impact on fuel consumption.

"Although the fuel savings from hybrid vehicles to date is relatively small compared to the total fuel use, as the technology matures and these numbers increase, they can have a significant impact on reducing our overall transportation fuel use."
