As of October 2007 US Energy is operating in 3 segments due to its recent acquisition of Seaspray Aerosol, Inc.

The alternative fuels market segment through the design and sale of our patent dual-fuel, diesel-natural gas conversion systems. In June of this year General Motors announced that our dual fuel kit had successfully completed the 100,000 km and that further development was not needed. The next step is to commence kit sales and conversion of GM vehicles in Thailand. Having the GM certification in hand, it was decided to cancel all further R&D expenses and to shut down the Atlanta Facility and sell all R&D equipment and excess Inventory. The Atlanta facility did not support the manufacture of kits and AEC was already producing all of the electrical components and has successfully outsourced all of the mechanical components. This decision dramatically reduced the expenses of USEI.
