The Pentagon in Washington D.C. has decided to go green.  Clean Technica has it that the Department of Defense has decided to install 4,000 LED fixtures to illuminate Wedge 5 of the governmental building. The company working on this project is called Cree and the LEDs will reduce power consumption by about 22%.

The Department of Energy reported that LED lights saved USA 8.7 trillion watt hours in 2007.  The cost is about $380 per fixture.  Installing the LEDs was written about in Title III of a Department of Defense program: “promote creation and strengthening of domestic industrial capabilities to support national security needs.”

The LED program is expected to pay for itself within four years.
