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.
Marine
Marine is an adjective meaning of or pertaining to the sea or ocean.
Wind
Wind is the flow of gases on a large scale. On the surface of the Earth, wind consists of the bulk movement of air. In outer space, solar wind is the movement of gases or charged particles from the Sun through space, while planetary wind is the outgassing of light chemical elements from a planet's atmosphere into space. Winds are commonly classified by their spatial scale, their speed, the types of forces that cause them, the regions in which they occur, and their effect. The strongest observed winds on a planet in the Solar System occur on Neptune and Saturn. Winds have various aspects, an important one being its velocity (wind speed); another the density of the gas involved; another its energy content or wind energy. Wind is also a great source of transportation for seeds and small birds; with time things can travel thousands of miles in the wind.
Energy
You will soon be able to tax it.
Michael Faraday to William Gladstone on the future use of electricity
Wind
What wind blew you hither, Pistol?
Not the ill wind which blows no man to good.
William Shakespeare, Henry IV, Part II (c. 1597-99), Act V, scene 3, line 89.
Wind
La nuit n'était pas très obscure; c'était une pleine lune sur laquelle couraient de larges nuées chassées par le vent. Cela faisait au dehors des alternatives d'ombre et de clarté, des éclipses, puis des éclaircies, et au dedans une sorte de crépuscule. Ce crépuscule, suffisant pour qu'on pût se guider, intermittent à cause des nuages, ressemblait à l'espèce de lividité qui tombe d'un soupirail de cave devant lequel vont et viennent des passants.
The night was not very dark; there was a full moon, across which large clouds were driving before the wind. This produced alternations of light and shade, out-of-doors eclipses and illuminations, and in-doors a kind of twilight. This twilight, enough to enable him to find his way, changing with the passing clouds, resembled that sort of livid light which falls through the window of a dungeon before which men are passing.
