Production in Sufficient Quantity
The World production of vegetable oil seed is forecast to be 418 million tonnes in 2008/09. After pressing this will make 131 million tonnes of vegetable oil. Much of this is from Oil Palm, and palm oil production is growing at 5% per year. At about 7.5 lb/USgal (900 g/L) this is about 38 billion USgallons (144 billion L). Currently vegetable oil is mostly used in food and some industrial uses with a small percentage used as fuel. The major fuel usage is by conversion to biodiesel with about 3 billion US gallons (11,000,000 m3) in 2009.
In 2004 the US consumed 530 billion litres (140 billion USgal) of gasoline and 150 billion litres (40 billion USgal) of diesel. In biodiesel it says oil palm produces 5940 litres per hectare (635 USgal/acre) of palm oil each year. To make 180 billion US gallons (680,000,000 m3) of vegetable oil each year would require 1,150,000 square kilometres (440,000 sq mi) or a square of land 1,070 kilometres (660 mi) on a side.
"The gradual move from oil has begun. Over the next 15 to 20 years we may see biofuels providing a full 25 percent of the world's energy needs. While the move is good for reducing greenhouse emissions, soaring oil prices have encouraged most countries to 'go green' by switching to greater use of biofuels." - Alexander Müller, Assistant Director-General of Sustainable Development at the FAO.
Algaculture could potentially produce far more oil per unit area. Results from pilot algaculture projects using sterile CO2 from power plant smokestacks look promising.
Genetic modifications to soybeans are already being used. Genetic modifications and breeding can increase vegetable oil yields. From 1979 to 2005 the soybean yield in bushels per acre more than doubled. A company has developed a variety of camelina sativa that yields 20% more oil than the standard variety.

Famous quotes containing the words production, sufficient and/or quantity:
“It is part of the educator’s responsibility to see equally to two things: First, that the problem grows out of the conditions of the experience being had in the present, and that it is within the range of the capacity of students; and, secondly, that it is such that it arouses in the learner an active quest for information and for production of new ideas. The new facts and new ideas thus obtained become the ground for further experiences in which new problems are presented.”
—John Dewey (1859–1952)
“Women have seldom sufficient employment to silence their feelings; a round of little cares, or vain pursuits frittering away all strength of mind and organs, they become naturally only objects of sense.”
—Mary Wollstonecraft (1759–1797)
“Upon looking back from the end of the last chapter and surveying the texture of what has been wrote, it is necessary, that upon this page and the five following, a good quantity of heterogeneous matter be inserted, to keep up that just balance betwixt wisdom and folly, without which a book would not hold together a single year.”
—Laurence Sterne (1713–1768)
