According to the Defense Science Board Task Force on DoD Energy Strategy, More Flight, Less Fuel, the military is the largest energy user in the federal government. The Department of Defense spends approximately $20 billion on energy and accounts for 80 percent of the US government’s total energy consumption.
Navy Secretary Ray Mabus has made energy conservation a priority for the Navy. Under his leadership, the Navy has established ambitious goals which include changing the way the Navy and Marine Corps award contracts during the acquisition process to consider the lifetime energy cost of the system; creating a “Green Strike Group” composed of nuclear vessels and ships powered by biofuels; reducing petroleum use in its 50,000 commercial vehicle fleet by 50 percent by phasing in hybrid fuel and electric vehicles; producing at least half the shore-based energy requirements from renewable sources; and ensuring at least 40 percent of the Navy’s total energy consumption comes from alternative sources by 2020.
Examples of how the Navy has begun to implement these ambitious energy conservation goals include:
· Savings of 386,000 barrels of fuel during the first half of fiscal year 2010 as part of the Incentivized Energy Conservation (i-ENCON) initiative which encourages ships to operate in the most efficient manner while conducting their mission;
· Construction of a $613,000 green roof at Naval Station Norfolk to be completed in December 2010; and
· Retrofitting of lighting and HVAC systems in more than 90 naval buildings at four Portsmouth, VA facilities through an Energy Savings Performance Contract (ESPC). The contract, awarded in December 2009, will see a total energy savings of 32,802 million British thermal units (MBTU) per year and an estimated annual cost savings of nearly $687,000.
