The resource information related to the energy system is an important element to the COFFEE model. Energy resource availability influences the choices of how to supply the demand. The resource supply curve is used to define the accessible amount of resource and its costs. This information was developed for the following resources:
• Oil and associated gas resources • Natural Gas and NGL resources • Coal resources • Uranium Resources • Hydro Energy • Solar and Wind Energy • Carbon Transportation and Storage
In addition, agricultural crops and residues are increasingly seen as sources of feedstocks for energy to displace fossil fuels. A wide range of materials has been proposed for use, including grain, crop residue, cellulosic crops (e.g., switchgrass, sugarcane), and various tree species (IPCC, 2007). In this model the feedstocks considered for bioenergy production include primary sources and secondary sources, such as residues.
