The methodology, schematically displayed in Figures 3 and 4, responds to the need to perform an in-depth analysis of the agricultural sector's ability to be a significant source of energy. Figure 3 is a schematic of the process to achieve the first objective that begins with the definition of the energy targets for energy produced with agricultural feedstocks. This information plus data on conversion costs for agricultural and forest feedstock is introduced into POLYSYS to estimate the quantity and type of energy to be produced from agriculture, as well as the price, income and other economic impacts derived from producing such a level of energy production. The second diagram, Figure 4, reflects the process to estimate the overall economic impacts of producing renewable energy from agricultural feedstock. This estimation seeks not only to quantify the impacts of producing the feedstock but also the impacts of the conversion processes on the overall economy.

From the diagrams it is clear that the key analytical instrument for the first objective is POLYSYS, a dynamic agricultural sector model. For the second objective the two main components are PII, the POLYSYS IMPLAN Integrator that takes information from POLYSYS, aggregates the information to a state level and modifies IMPLAN input files, and IMPLAN, an input-output model. These models are combined to provide a detailed picture of not only the agricultural sector and potential impacts of providing energy feedstocks, but also the impacts to the economy as these feedstocks are produced, transported, and converted to energy.

Global warming is a huge problem which will significantly affect every country in the world. Many people all over the world are trying to do whatever they can to help combat the effects of global warming. One of the ways that people can fight global warming is to reduce their dependence on non-renewable energy sources like oil and petroleum based products.
