EPA Energy Use 1985-2002

This graph shows EPA's progress towards the energy reduction goals set forth in Executive Order 13123, Greening the Government Through Efficient Energy Management.

Beginning in 1985, with an annual energy consumption of 400 thousand British Thermal Units (Btu) per square foot, EPA rapidly decreased energy use to 357 thousand Btu per square foot in 1990. From 1990 to 2000, EPA energy use was fairly constant, with a slight spike in 1992, a slight dip in 1993, and another slight spike in 1999. Projected energy use at EPA facilities is expected to continue decreasing in the next few years.

EPA purchases green power for a few of its facilities. Green power has little or no associated greenhouse gas emissions. Adjusting the data by eliminating the Btu derived from green power further decreases EPA's BTU per square foot calculation to 373 thousand in 1999 and 359 thousand in 2000. Future green power purchases are expected to cause EPA's energy use to be reduced further.

EPA is constructing new facilities in RTP, North Carolina. Upon completion, EPA estimates that energy use at the facility will be reduced significantly. RTP's contribution is expected to decrease EPA's annual energy use to 310 thousand Btu per square foot in 2002.

These measures will bring EPA closer to its energy reduction goals of 285 thousand Btu per square foot in 2005 and 268 thousand Btu per square foot in 2010.

Energy/Water Reduction Results

These three tables compare EPA's energy consumption for Fiscal Years 1990 and 2000, and Fiscal Years 1999 and 2000, and EPA's water consumption for Fiscal Years 1999 and 2000.

The first table compares EPA's energy consumption in FY 1990 with energy consumption in FY 2000. In FY 1990, EPA facilities consumed 357,334 British Thermal Units (Btu) per square foot and 746,972 million Btu. In FY 2000, EPA facilities consumed 361,933 Btu per square foot and 1,129,171 million Btu. This represents a 1.29 percent increase in Btu per square foot and a 51.17 percent increase in Btu between FY 1990 and FY 2000.

The second table compares EPA's energy consumption in FY 1999 with energy consumption in FY 2000. In FY 1999, EPA facilities consumed 375,263 British Thermal Units (Btu) per square foot and 1,166,926 million Btu. In FY 2000, EPA facilities consumed 361,933 Btu per square foot and 1,129,171 million Btu. This represents a 3.55 percent decrease in Btu per square foot and a 3.24 percent decrease in Btu between FY 1999 and FY 2000.

The third table compares EPA's water consumption in FY 1999 with water consumption in FY 2000. In FY 1999, EPA facilities consumed 59.17 gallons of water per square foot and 184.6 million gallons of water. In FY 2000, EPA facilities consumed 60.02 gallons of water per square foot and 187.3 million gallons of water. This represents a 1.44 percent increase in gallons of water per square foot and a 1.44 percent increase in gallons of water consumed between FY 1999 and FY 2000.
