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 is nothing more likely to drive a man mad, than the being unable to get rid of the idea of the distinction between right and wrong, and an obstinate, constitutional preference of the true to the agreeable.”
—William Hazlitt (1778–1830)
“I realized early on that the academy and the literary world alike—and I don’t think there really is a distinction between the two—are always dominated by fools, knaves, charlatans and bureaucrats. And that being the case, any human being, male or female, of whatever status, who has a voice of her or his own, is not going to be liked.”
—Harold Bloom (b. 1930)
“All my energy and attention were devoted to trying to help her solve her problems. Unfortunately I didn’t have much success.”
—Arthur Miller (b. 1915)
“No power on earth or above the bottomless pit has such influence to terrorize and make cowards of men as the liquor power. Satan could not have fallen on a more potent instrument with which to thrall the world. Alcohol is king!”
—Eliza “Mother” Stewart (1816–c. 1908)
