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:
“What! Would you make no distinction between hypocrisy and devotion? Would you give them the same names, and respect the mask as you do the face? Would you equate artifice and sincerity? Confound appearance with truth? Regard the phantom as the very person? Value counterfeit as cash?”
—Molière [Jean Baptiste Poquelin] (1622–1673)
“There is a distinction to be drawn between true collectors and accumulators. Collectors are discriminating; accumulators act at random. The Collyer brothers, who died among the tons of newspapers and trash with which they filled every cubic foot of their house so that they could scarcely move, were a classic example of accumulators, but there are many of us whose houses are filled with all manner of things that we “can’t bear to throw away.””
—Russell Lynes (1910–1991)
“I have witnessed the tremendous energy of the masses. On this foundation it is possible to accomplish any task whatsoever.”
—Mao Zedong (1893–1976)
“The dignity and stability of government in all its branches, the morals of the people, and every blessing of society, depend so much upon an upright and skilful administration of justice, that the judicial power ought to be distinct from both the legislative and executive, and independent upon both, that so it may be a check upon both, as both should be checks upon that.”
—Thomas Jefferson (1743–1826)
