Energy Consumption
A RAND study in 2005 estimated that production of 100,000 barrels per day (16,000 m3/d) of oil (5.4 million tons/year) would theoretically require a dedicated power generating capacity of 1.2 gigawatts (10 billion kWh/year), assuming deposit richness of 25 US gallons (95 l; 21 imp gal) per ton, with 100% pyrolysis efficiency, and 100% extraction of pyrolysis products. If this amount of electricity were to be generated by a coal-fired power plant, it would consume five million ton of coal annually (about 2.2 million toe).
In 2006, Shell estimated that over the project life cycle, for every unit of energy consumed, three to four units would be produced. Such an "energy returned on energy invested" would be significantly better than that achieved in the Mahogony trials. For the 1996 trial, Shell applied 440,000 kWh (which would require about 96 toe energy input in a coal-fired plant), to generate 250 barrels (40 m3) of oil (37 toe output).

Famous quotes containing the words energy and/or consumption:
“Three elements go to make up an idea. The first is its intrinsic quality as a feeling. The second is the energy with which it affects other ideas, an energy which is infinite in the here-and-nowness of immediate sensation, finite and relative in the recency of the past. The third element is the tendency of an idea to bring along other ideas with it.”
—Charles Sanders Peirce (1839–1914)
“The basis on which good repute in any highly organized industrial community ultimately rests is pecuniary strength; and the means of showing pecuniary strength, and so of gaining or retaining a good name, are leisure and a conspicuous consumption of goods.”
—Thorstein Veblen (1857–1929)
