Variable speed pumps in a recreation complex save a college thousands of dollars per year in energy costs.

Pumping systems consume a significant portion of global electrical energy, accounting for nearly 20 percent of the energy used by electric motors and 25 to 50 percent of the total electrical usage in certain industrial facilities.
Ironically, pumping systems are rarely included in energy-efficiency calculations, even though pumps present such energy-savings potential. One could argue that mentioning “motor” or “variable speed drive” (VSD) is sufficient because these components indicate the greatest energy-savings opportunity in a pumping system.
