Iowa State researcher David Swenson isn't convinced there will be a jobs bonanza as a result of increased ethanol production. Speaking at a biofuel conference in Canada, Swenson worries that politicians are encouraged by inaccurate economic models. He points to a scenario from the National Corn Growers Assn. that suggests a total of 2,000 new jobs could be generated by a large ethanol plant. Swenson estimates 150 new jobs. Canada is looking to increase its ethanol production and has a goal of five percent ethanol content in all gasoline. The government has predicted 450 jobs directly from ethanol and more from the agriculture industry. One official agreed with some of Swenson's points but stresses there will be economic benefits of increased ethanol production.
