The researchers made preliminary estimates based on assumptions about the ultimate design and operation of each prison and its thermal and electrical energy requirements. Each site was reviewed for its potential for using any of the following technologies: cogeneration, wind, solar, refuse, biomass, and geothermal. Development of several sample cases for various technologies permitted a preliminary economic analysis of the associated technologies at each site. Results of these economic analyses determined the attractiveness of equipping a site with an alternative power supply system. Data tables, figures, and site plans.
