The Military Engineer l No. 66249 Army Employs HEVs and LSEVs to Save Fuel The Army is working to reduce gasoline consumption with a variety of strategies, including the use of hybrid-electric ve- hicles (HEV) and light, slow electric vehicles (LSEV). HEVs, which combine a conventional fossil fuel propul- sion system with a rechargeable energy storage system, are more fuel ef?cient than gas-only vehicles but achieve similar performance. The feature most responsible for conserving gas takes over when the vehicle comes to a complete stop, as frequently happens in urban driving: The gas engine shuts off rather than waste gas while idling. The vehicle is technically still running, however, by way of the electric power source, which continues until the car accelerates from the stopped position and begins moving again. The Army began leasing HEVs from the U.S. General Services Administration (GSA) earlier this year, and nearly 500 HEVs have already been delivered to Army installations. LSEVs are fully electric, and can range approximately 40-mi at about 35-mph between charges. LSEVs will mainly be used for administrative trips, transportation at ?ight lines and other trips around post. Before the new vehicles arrive at a post, small re- charging stations will be constructed. Roughly 1,600 LSEVs are expected at Army posts during the next two years.

EMS conformance is a highly-visible requirement for NAVFAC and Commander Navy Installations Command. NAVFAC Far East achieved full compliance ahead of the Sept. 30 deadline at Commander Fleet Activities Yokosuka, Com- mander Fleet Activities Sasebo, Commander Fleet Activities Okinawa, Naval Air Facility Atsugi, Naval Support Facility Di- ego Garcia and Commander Fleet Activities Chinhae. EMS is a formal management framework intended to help an organization achieve its internal environmental goals through repeatable and consistent control of its operations. It systematically uses ?ve basic components—policy, planning, implementation, checking or corrective action, and manage- ment review—to achieve full compliance with legal require- ments and continual improvement in mission performance. Nearly 3,000 employees at the six NAVFAC Far East installa- tions completed EMS awareness training this year. It has exponentially increased employee awareness of how their duties affect the environment, and how to complete the mission in an environmentally-friendly manner, which will ultimately save the Navy countless time, energy and money in the future through proactive environmental management and coordination, Michael Corry, NAVFAC Far East Environ- mental Engineer, emphasized. Corry added that implementation of EMS at NAVFAC Far East has resulted in numerous bene?ts to the organization, such as streamlined training records documentation, envi- ronmental management plans, standard operating proce- dures and guidance.

Hydro- kinetic projects, which produce power from moving water without the use of a dam, include wave-energy systems and in-stream turbines, which can capture the energy from tidal ?ows or the ?ow of a river. The Hastings project, an in-stream turbine from Hydro Green Energy, captures the ?ow from the output channel of an existing hydropower dam. The turbine, anchored down- stream from the dam on a tethered barge, has a nameplate capacity of 100-kW, and an expected output of about 35-kW. After approval of the project by the Federal Energy Regu- latory Commission last December, the turbine was quickly installed on the barge and has been undergoing testing since February. The turbine was evaluated for its impact on ?sh Environment & Energy News
