Energy & Water

In fiscal year 2019, Federal facilities used 316 trillion Btu of energy and 122 billion gallons of water. OFHPGB works closely with the U.S. Department of Energy’s Federal Energy Management Program and other agencies and partners to pilot and promote innovative energy and water saving practices – meeting the requirements of Federal statutes and Executive Orders while saving millions of dollars of taxpayer money.
