Energy Resources and the Role of Nuclear Energy

Abstract

Energy is broadly defined as the ability to produce a change from the existing conditions. Thus, the term energy implies that a capacity of action present. The evaluation of energy is done by measuring certain effects that are classified by descriptive names, and these effects can be produced under controlled conditions. For example, a mass that is located at certain position may have a potential energy or if the same mass is in motion then it may possess the kinetic energy or if its characteristics of composition such as temperature or pressure changes, then it is going through an energy process which is called internal energy. The internal energy can be measured by release of an amount by change in potential energy experienced by external load.
