Distinction Between Energy and Power

Although in everyday usage the terms energy and power are essentially synonyms, scientists and engineers distinguish between them. In its technical sense, power is not at all the same as energy, but is the rate at which energy is converted (or, equivalently, at which work is performed). Thus a hydroelectric plant, by allowing the water above the dam to pass through turbines, converts the water's potential energy into kinetic energy and ultimately into electric energy, whereas the amount of electric energy that is generated per unit of time is the electric power generated. The same amount of energy converted through a shorter period of time is more power over that shorter time.

Famous quotes containing the words distinction between, distinction, energy and/or power:

    There appears to be but two grand master passions or movers in the human mind, namely, love and pride. And what constitutes the beauty or deformity of a man’s character is the choice he makes under which banner he determines to enlist himself. But there is a strong distinction between different degress in the same thing and a mixture of two contraries.
    Sarah Fielding (1710–1768)

    Genocide begins, however improbably, in the conviction that classes of biological distinction indisputably sanction social and political discrimination.
    Andrea Dworkin (b. 1946)

    A government deriving its energy from the will of the society, and operating, by the reason of its measures, on the understanding and interest of the society ... is the government for which philosophy has been searching and humanity been fighting from the most remote ages ... which it is the glory of America to have invented, and her unrivalled happiness to possess.
    James Madison (1751–1836)

    Rocked in the cradle of the deep
    I lay me down in peace to sleep;
    Secure I rest upon the wave,
    For Thou, O Lord! hast power to save.
    Emma Hart Willard (1787–1870)
