31Water efficiency — can be defined as *1) the accomplishment of a function, task, process, or result with the minimal amount of water feasible; *2) an indicator of the relationship between the amount of water required for a particular purpose and the amount of water …
32Renewable Energy and Energy Efficiency Partnership — The Renewable Energy and Energy Efficiency Partnership (REEEP) is an active, global public private partnership that was launched by the United Kingdom along with other partners at the Johannesburg World Summit on Sustainable Development (WSSD) in …
33Spectral efficiency — Spectral efficiency, spectrum efficiency or bandwidth efficiency refers to the information rate that can be transmitted over a given bandwidth in a specific communication system. It is a measure of how efficiently a limited frequency spectrum is… …
34Energy conversion efficiency — Output energy is always lower than input energy …
35Volumetric efficiency — in internal combustion engine design refers to the efficiency with which the engine can move the charge into and out of the cylinders. More correctly, volumetric efficiency is a ratio (or percentage) of what volume of fuel and air actually enters …
36Data Efficiency — refers to efficiency of the many processes that can be applied to data such as storage, access, filtering, sharing, etc., and whether or not the processes lead to the desired outcome within resource constraints.A management definition of Data… …

38Distributive efficiency — In welfare economics, distributive efficiency occurs when goods and services are received by those who have the greatest need for them. Abba Lerner first proposed the idea of distributive efficiency in his 1944 book The Economics of Control.… …
39Thermal efficiency — In thermodynamics, the thermal efficiency (eta {th} ,) is a dimensionless performance measure of a thermal device such as an internal combustion engine, a boiler, or a furnace, for example. The input, Q {in} ,, to the device is heat, or the heat… …
40Exergy efficiency — (also known as the second law efficiency or rational efficiency) computes the efficiency of a process taking the second law of thermodynamics into account.MotivationFrom the second law of thermodynamics it can be demonstrated that no system can… …
