1Engine efficiency — of thermal engines is the relationship between the total energy contained in the fuel, and the amount of energy used to perform useful work. There are two classifications of thermal engines (1) Internal combustion (gasoline, diesel and gas… …
2Energy efficiency in British housing — Domestic housing in the United Kingdom presents one of the major opportunities for achieving the 20% overall cut in UK carbon dioxide emissions targeted by the Government for 2010.Carbon emissionsAlthough carbon emissions from housing have… …
3High efficiency solar cells — are solar cells specifically designed to generate electricity in a cost effective and efficient manner. In 1994, the University of New South Wales reported the highest silicon solar cell efficiency of 24.7% with their PERL cell technology. In… …
4Algorithmic efficiency — In computer science, efficiency is used to describe properties of an algorithm relating to how much of various types of resources it consumes. Algorithmic efficiency can be thought of as analogous to engineering productivity for a repeating or… …
5Propulsive efficiency — In aircraft and rocket design, overall propulsive efficiency eta is the efficiency, in percent, with which the energy contained in a vehicle s propellant is converted into useful energy, to replace losses due to air drag, or gravity, or to… …
6Renewable 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 …
7Quantum efficiency — (QE) is a quantity defined for a photosensitive device such as photographic film or a charge coupled device (CCD) as the percentage of photons hitting the photoreactive surface that will produce an electron–hole pair [… …
8Battle Efficiency Award — The Battle Efficiency Award, commonly known as the Battle E is awarded annually to the small number of U.S. Navy ships, submarines, aviation and other units that win their battle efficiency competition.The criterion for the Battle Efficiency… …
9Productive efficiency — occurs when the economy is operating at its production possibility frontier (PPF). This takes place when production of one good is achieved at the lowest cost possible, given the production of the other good(s). Equivalently, it is when the… …
