As A Possible Renewable Energy Source
See also: Biomass energy, Algae fuel
Kelp has a high rate of growth and its decay is quite efficient in yielding methane, as well as sugars that can be converted to ethanol. It has been proposed that large open-ocean kelp farms could serve as a source of renewable energy. Unlike some biofuels such as corn ethanol, kelp energy avoids "food vs fuel" issues and does not require irrigation.

Famous quotes containing the words energy and/or source:
“Because humans are not alone in exhibiting such behavior—bees stockpile royal jelly, birds feather their nests, mice shred paper—it’s possible that a pregnant woman who scrubs her house from floor to ceiling [just before her baby is born] is responding to a biological imperative . . . . Of course there are those who believe that . . . the burst of energy that propels a pregnant woman to clean her house is a perfectly natural response to their mother’s impending visit.”
—Mary Arrigo (20th century)
“If, for instance, they have heard something from the postman, they attribute it to “a semi-official statement”; if they have fallen into conversation with a stranger at a bar, they can conscientiously describe him as “a source that has hitherto proved unimpeachable.” It is only when the journalist is reporting a whim of his own, and one to which he attaches minor importance, that he defines it as the opinion of “well-informed circles.””
—Evelyn Waugh (1903–1966)
