How many gallons of oil does a super-tanker hold? Now, how may deep fryers will it take to fill up a super-tanker? How many super-tankers arrive in the U.S. every day? There ain't enough animal fat to go around to fill all those tankers. Better start making more cows!
From Wiki: Production levels
Biodiesel production capacity is growing rapidly, with an average annual growth rate from 2002-2006 of over 40%. For the year 2006, the latest for which actual production figures could be obtained, total world biodiesel production was about 5-6 million tonnes, with 4.9 million tonnes processed in Europe (of which 2.7 million tonnes was from Germany) and most of the rest from the USA. The capacity for 2007 in Europe totalled 10.3 million tonnes. This compares with a total demand for diesel in the US and Europe of approximately 490 million tonnes (147 billion gallons). Total world production of vegetable oil for all purposes in 2005/06 was about 110 million tonnes, with about 34 million tonnes each of palm oil and soybean oil.
