It has only been in the past few years that interest in jatropha as a biofuel crop has mounted, particularly because of its purported ability to thrive on marginal land and in drought conditions.
As for claims about the tree's fast-growing nature, early fruiting, pest and disease resistance due to its toxicity, and its potential to not only produce biodiesel, but also as fuel for light and heat for cooking.

With the UK going coal-free for a record-breaking 90 hours over the weekend, energy sources such as solar and onshore wind now play a key role in generating electricity. However, with the urgent need for new energy sources to replace the 60% of the electricity produced worldwide by fossil fuel combustion, it has become necessary to look further afield to alternative energy sources.

-
The main finding of the Reality Check is that jatropha is not economically viable when grown by smallholders in Kenya, either in a monoculture or intercrop plantation model. This is due to low yields and high production costs, and a lack of guidelines for applying agronomic and silvicultural best practices.
