In 2007, wind capacity reached 93,849 MW (WWEA, 2008).• The average annual growth rate in the last 10 years
was close to 30%
In 2007, photovoltaic (PV) capacity reached 9,100 MW (EPIA, 2008).
• Solar PV has a ten-year average annual growth rate of 31%
In 2006, geothermal capacity reached 9,600 MW (BP, 2008).
Assuming there is no intercropping needed, just jatropha plants, testing shows one can obtain an average of 7.5 kilograms of fruit or 3 kilograms of seeds per tree.
Therefore, 6 tons/acre.
At a minimum, several hundred acres of land needed for commercial operation.
How many tons of Jatropha seeds per acre?

How many liters of oil per 1,000 acres?
With an average ratio conversion of 40% from seeds into Jatropha oil, trees can produce 2,400 tons of Jatropha oil per 1,000 acres.
Applying a density rate of 0.9 kg/cm3, it is possible to obtain 2.7 Million liters of oil from 1,000 acres of land per year.
2.646 million liters of biodiesel per 1000 acres
