Marketplace provides data relevant to the production of biofuels from biomass as well as the state of the petroleum markets in which biofuels are used. Cost fluctuations in the price of a bushel of soybeans, the main biodiesel feedstock, and corn, affect the finished products i.e., biofuels. Key indicators in the petroleum industry provide a snapshot of the supply of finished products stocks and production, and how they relate to demand and the price of finished product (i.e. gasoline and diesel). The tables show actual grain prices, indicators which may affect gasoline prices, and the production of ethanol.
