Turn off the lights! Feds' $7B power bill in cross hairs

The government has just three years left to cut energy at its facilities by nearly one-third. And with power costs rising and Congress slashing budgets, energy conservation efforts are all the more pressing.

Energy spending government-wide increased 7 percent from more than $18.6 billion in fiscal 2009 to $20.0 billion in fiscal 2010, mainly because of price increases for petroleum-based fuels, according to the Energy Department.

Agencies are seeking savings from that spending so energy costs for buildings, vehicles and equipment can be cut and funds can be repurposed to pay for unfunded green-government mandates. More specifically, they see reducing the $7 billion spent to light, heat and cool their buildings as one way to be successful.

Agencies must reduce energy use in their facilities by 30 percent from a 2005 baseline by 2015 — a requirement of the 2007 Energy Independence and Security Act.

"There is nothing overly sexy about the projects we do — they are just basic projects that allow us to make the buildings more efficient," said Thomas Day, chief sustainability officer at the U.S. Postal Service.

The Postal Service established "green teams" in 2009 to emphasize more efficient behavior at its facilities.

Employees helped save $5 million in 2010 by reducing spending on consumable materials such as office supplies and electricity.

Further, the agency tracks all utility bills through a main system that helps identify areas for savings or efficiency projects. Such projects include upgrading heating and ventilation systems, replacing old windows and lights, and installing motion sensors to turn off lights when an employee leaves the room.Cost effective energy efficiency brightstalo is the goal and daylight harvesting is increasingly recognized as a solution by both the private

The agency has reduced its energy footprint from 115,000 BTUs per square foot in 2003 to 74,000 in 2010, Day said.

BTUs — or British thermal units — are a standard energy industry measure for energy use. Cutting 10,000 BTUs per square foot can save, on average, more than $2,500 a year per square foot in energy costs, based on Energy Information Administration data.LED current and ledbulbsui handle the peak input voltage minus the drop across two of the four rectifier diodes

In addition to installing energy-efficient lighting and motion sensors to detect when lights and heat can be turned off, it has trained 31 building energy managers to conduct weekly or monthly building inspections to identify where energy is being wasted and how money can be saved.

Norma Barrera, Kingsville's energy manager, said the Navy incorporates suggestions from the inspections into energy-efficiency programs, such as providing weather stripping to exterior doors in their buildings and vestibules.News on solar energy harvesting bestledlightbulbs has been focused lately on individual success with the older style of solar paneling.

Other agencies such as the Justice Department are turning to contractors for help in reducing their building energy costs.
