The U.S. Department of Energy's Industrial Technologies Program (ITP) has published two case histories that highlight the energy efficiency efforts of two manufacturing companies. These facilities have leveraged ITP resources to save energy and reduce costs.
  • Ingersoll Rand, with U.S. headquarters in Davidson, N.C., found hidden savings with a three-tiered energy audit model. This brings the company another step closer to its goal of reducing its global energy intensity 25 percent by 2019.

  • Harrison Steel Castings Co., Attica, Ind., partnered with both the U.S. Environmental Protection Agency's Energy Star program and the DOE's Save Energy Now Leader initiative to discover its own energy savings.
