Noun

negawatt (plural negawatts)

1. A unit of saved energy.
   • 24 December 2000, Barbara Whitaker, “A Lightning Rod in California”, in New York Times:

     And he has suggested ways to help consumers buy the so-called time-of-use-meters […] so they can benefit from using energy at off-peak times and through "negawatts," or credits for not using power.

   • 7 July 2008, Amory B. Lovins, “The Case For Efficiency”, in Forbes:

     Three-fourths of U.S. electricity--69% of which is used in buildings, nearly all the rest in industry--can be saved for less than the price of just running a coal or nuclear plant. This "negawatt" potential is not just in smarter motors, lights, appliances, etc., but even more in their larger systems.
