Institution COPPE/UFRJ (Cenergia), Brazil,
Solution concept General equilibrium (closed economy)
Solution method The COFFEE model is solved through Linear Programming (LP). The TEA model is formulated as a mixed complementary problem (MCP) and is solved through Mathematical Programming System for General Equilibrium -- MPSGE within GAMS using the PATH solver.

Energy resource endowments in the COFFEE model 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.
