"There’s enough energy in ten minutes of one hurricane to match the nuclear stockpiles of the world."

"One pound of anything, when it is completely converted into energy, in keeping with Einstein’s mathematical equation E=mc2, will produce 11,400 million kilowatt hours of energy."

"If one gram (one-twenty-eighth of an ounce) of matter could be converted into its equivalent of pure energy and the energy used with perfect efficiency to keep a 1,000 watt light bulb glowing, there would be enough energy to keep it lit for 2,850 years, or from the time of Homer to the present."

"The energy contained in a breaking ocean wave is immense. Measurements made with wave dynamometers have shown some waves striking with a force equal to a pressure of 6,000 pounds per square foot. The energy content of a four-foot swell moving along a hundred mile front would supply power to a city the size of Seattle for almost twenty-four hours."

"The Earth receives only about one-half of one-billionth of the sun’s radiant energy. But in just a few days it gets as much heat and light as could be produced by burning all the oil, coal, and wood on the planet."

"The total quantity of energy in the universe is constant; energy cannot be created, and it cannot be destroyed. One form of energy can be converted into another, or transported from one place to another. But that is as much as can be done. When energy is used, it doesn’t disappear; it merely goes elsewhere or is changed into another form."
