biofuels may provide a substitute for diesel fuel that can be manufactured locally for a lower price, independent of the international oil price. the local production and use of biofuel also offers other benefits such as improved energy security, rural development opportunities and environmental benefits. the jatropha curcas species appears to be a particularly suitable source of biofuel as it already grows commonly in cambodia. local sustainable production of biofuel in cambodia, based on the jatropha or other sources, offers good potential benefits for the investors, the economy, rural communities and the environment.
