Thus vegetable oil does not increase the CO in the atmosphere, and does not directly contribute to the problem of greenhouse gas. It is really a way of catching and storing solar energy; it is a renewable energy. However, as with other "renewable" energy sources, there may be a (relatively small) carbon footprint associated with production or distribution of vegetable oil. Vegetable oil is far less toxic than other fuels such as gasoline, petroleum-based
