The Concept Of Efficiency

A primary pre-requisite for the specifications and computations of energy resource conservation measures is parameter for evaluating the efficiency of the energy system or procedure with reference to energy utilization. However “efficiency” is generally used idea in engineering, and has an aura of decency and comprehensiveness about it, it is frequently an ambiguous and vague measure, mainly when it is not defined and fit rightfully.

For illustration, what does it mean in the statement below in Asimov’s Book of particulars: ‘Early guns took too long to load and fire which bows and arrows – in trained hands – were twelve times more efficient’?

In a given circumstance, it is generally possible to state numerous different forms of efficiency, based upon what is considered to be the output and what is considered as the input, all of which will not have similar importance or relevance.
