Recent studies indicated that approximately 32% of laboratory and office building electricity consumption is attributed to “plug load” equipment. A plug load is electricity drawn from any equipment plugged into an outlet. Ref.: Inventorying Plug Load Equipment and Assessing Plug Load Reduction Solutions on a University Campus, Moira Hager, Stanford University, 10/2015Laboratory equipment that can be turned off when not in use are pumps, tissue culture hoods, incubators, ovens, microscopes, thermal cyclers, ovens, water baths (install an electrical timer), heating blocks, hot plates, and chilled centrifuges.
