Fuel for thought

Within a couple of years of the global rush to promote biofuels new questions are being asked about the claimed benefits of these fuels and serious negative impacts are coming to light. It is in this regard that the focus of the biofuel policy in India has been towards utilising an "oil bearing' plant, jatropha carcus, for oil extraction, processing and eventual blending with diesel. The advantage of this plant lies in the fact that it can be grown on cultivable wasteland and requires very little fertiliser and other inputs as normally required in agriculture.
