ECONOMIC IMPACT Cars that run on biodiesel can help the people. Modern diesel engine technology has advanced to the point where the advantages of biofuel usage are becoming much greater than the disadvantages. Modern diesel engines produce less noise, smoke or vibrations and they are more fuel-efficient than older model engines. Engines will last longer on when running on biodiesel. This would affect more developed countries who basically rely on vehicles for their main transportation. (Reference 7) |  |
 | SOCIAL IMPACT While corn farmers and palm oil plantation owners have been elated by the policies, critics have warned all along about the short-sightedness of these policies. Some, like Cornell Professor David Pimentel and Berkeley Professor Tad Patzek, argued that a full life-cycle analysis showed that most biofuels are actually net energy negative – that is it takes more fossil fuel energy to produce biofuels like ethanol than is returned in the process. This assertion, if true, would imply that expansion of biofuels would actually increase greenhouse gas emissions. However, Professors Pimentel and Patzek have their own critics, who assert that their studies made flawed assumptions. Farmers and maybe even food prices would rise and affect everyone in both positive and negative. (Reference 8) |
