Fig. 2.2. Comparative Assessment Classification System microwave interference, and changes in land value because of deployment of an energy technology. The economic and societal category is divided into two parts: macro- economic and socioeconomic. The macroeconomic issues deal with national and regional macroeconomic impacts (e.g., trade, GNP, capital availability, and employment). Socioeconomic issues concern the monetary impact and social stresses on the localities where power systems are sited. Institutional comparisons deal with the effects of existing and potential institutions on the deployment of a technology (regulatory impacts). International institutional issues are addressed in terms of their regulatory impact on energy systems. The resource category includes five subcategories: land, labor, materials, energy, and water. Here, key concerns include resource limits, production limits, dependence on foreign resources, and need for new skilled labor. 2.3 SELECTION OF ENERGY ALTERNATIVES The technologies initially considered for comparison with the SPS listed in Table 2.1 include six fossil options, ten nuclear technologies (including two fusion options), five solar technologies, and three geothermal technologies. The list was narrowed to six technologies according to the following criteria: • Technical data must be available in sufficient detail to allow adequate technical characterization and comparison.
