Vegetable oils as alternative energy carbon dioxide (CO) out of the Earth's atmosphere to make vegetable oil. The same CO is then put back after it is burned in an engine. 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
