Figure 9. Detailed energy model of Hillsborough County (Sipe et al . 1979), 



The energy circuit model of Hillsborough County, used as an example in 

 this section, was developed as part of the Energy Basis of the Hillsborough 

 County Project at the Center for Wetlands, University of Florida, sponsored by 

 the Hillsborough County Environmental Protection Agency, John F. Alexander, 

 Jr., and H. T. Odum, principal investigators. The simulation model was devel- 

 oped as part of the project by Dennis Swaney and report by Sipe, Swaney, and 

 McGinty (1979).
