I firmly believe that America's energy security should be this committee's top priority. 

Home-grown fuels, such as biodiesel, cellulostic ethanol and coal-to-liquids, can help move the United States towards greater energy independence, and can even help to clean the environment. 

As we begin work on energy independence legislation, I look forward to working with the Chairman to include a provision that I'm working on which would incentivize clean diesel. 

Diesel engines get an average of 30 percent greater fuel efficiency as gasoline engines, so putting more diesel cars on the road instead of a gasoline engine is like dramatically increasing the CAFE Standard. 

Using biodiesel in those diesel engines can further reduce our demand for petroleum. 

And, which this is not in our Committee's jurisdiction, I hope that the energy independence legislative package will also include my bill H.R. 927, which would provide parity for biodiesel produced from recycled restaurant grease -- something that we have in abundance in the Dallas-Fort Worth Metroplex. 

There are numerous challenges to be met as we seek to increase our use of alternative transportation fuels -- both in terms of technology, biology and chemistry, and in terms of supporting infrastructure.  I appreciate our witnesses appearing before us today to discuss these issues.

Mr. Chairman, I yield back.
