Fluid power is a term describing hydraulic and pneumatic technologies. Both technologies use a fluid (liquid or gas) to transmit power from one location to another. It is a workhorse of the U.S. economy. Fluid power systems transmit more power in a smaller space than other forms of power transmission, making it the cross-cutting technology of choice for dozens of industries and hundreds of applications.

These and other facts about fluid power can be found in the 2014 Annual Report on the U.S. Fluid Power Industry, published by the National Fluid Power Association. The report reviews both the size and economic impact of the industry, as well as explores the energy consumption, best practices and current R&D directions of fluid power technology.
