 NATCHEZ, MS--(MARKET WIRE)--Jul 17, 2007 -- U.S. Sustainable Energy Corp. (PINKSHEETS: USSE) and Sustainable Power Corp. (PINKSHEETS: SSTP) are pleased to jointly announce the dramatic results of testing of its revolutionary new green renewable Biodiesel by AmSpec Services, LLC (http://www.amspecllc.com).
 
 In a report published today on the USSEC Research page, results included improved flashpoint, higher viscosity, dramatically lower sulfur (ppm), less copper corrosion, higher cetane index, dramatically less carbon residue, and improved lubricity over conventional Ultra Low Sulfur Diesel.
 
 John Rivera, CEO, stated, "With these breakthrough test results, we believe we have come up with a solution to stop the importation of foreign diesel fuels. Our 'OD 66' or Oxygenated Diesel meets and exceeds all ASTM specifications. As previously announced, Sustainable Power Corp. has received the exclusive worldwide license to acquire USSEC Bio-Waste products to produce and distribute Biofuel. The companies anticipate that Sustainable Power will commence shipments of this new Biodiesel within 72 hrs."
