AMES, Iowa — The spreadsheets listed below provide data and trends for various components of the renewable energy industry. These files are updated with new information each month.
Energy prices and their grain feedstock prices are commodity prices that are vulnerable to large swings over time. This section provides time-series trends in these prices and their relationship to each other. Comparisons are presented for crude oil, diesel fuel and gasoline with corn and soybean prices. These monthly data series include comparisons between energy prices (crude oil, gasoline and diesel fuel) and crop prices (corn and soybeans).
The profitability of production for corn, ethanol, and biodiesel is extremely variable. Due to the volatile price nature of these products and their feedstocks, profitability can change rapidly from month to month. In addition, price variations of co-products such as distillers grains with solubles and the production facility’s energy source of natural gas add to the variability of profits. The models are updated with monthly input and output prices to show the changes in production profitability.
Balance sheets for ethanol and biodiesel, as well as their feedstocks of corn and soybean oil provide insight on available supplies, various sources of demand, and carryover stocks that are left at the end of the marketing year after all demands have been met.
