You may or may not know, but most food production uses a lot of oil. A lot of this oil is used in the production of fertilizer. As mentioned in the previous post, the University of Minnesota is working on a way to use windpower air and water to create nitrogen fertilizer. This would significantly reduce the amount of oil that is used on our nations fields. Providing a sustainable way to create fertilizer (if using fertilizer is a good idea or not I leave to another debate).
