Energy

In physics, energy is the quantitative property that must be transferred to an object in order to perform work on, or to heat, the object. Energy is a conserved quantity; the law of conservation of energy states that energy can be converted in form, but not created or destroyed. The SI unit of energy is the joule, which is the energy transferred to an object by the work of moving it a distance of 1 metre against a force of 1 newton.

Energy

If you take a bale of hay and tie it to the tail of a mule and then strike a match and set the bale of hay on fire, and if you then compare the energy expended shortly thereafter by the mule with the energy expended by yourself in the striking of the match, you will understand the concept of amplification.

William Shockley

Energy

It is important to realize that in physics today, we have no knowledge of what energy is. We do not have a picture that energy comes in little blobs of a definite amount.

Richard Feynman, in The Feynman Lectures on Physics (1964) Volume I, 4-1

Energy

Our decision about energy will test the character of the American people and the ability of the President and the Congress to govern this Nation. This difficult effort will be the "moral equivalent of war," except that we will be uniting our efforts to build and not to destroy.

Jimmy Carter, address to the nation on the energy problem (April 18, 1977); Public Papers of the Presidents of the United States: Jimmy Carter, 1977, book 1, p. 656. Carter was quoting William James, who used the phrase in his essay, "The Moral Equivalent of War".

Arctic rivers dump carbon into the sea

Researchers have shown for the first time how Arctic rivers are transporting vast quantities of organic carbon into the oceans. This process occurs as the permafrost melts, which is due to climate change.
