Introduction ENERGY ANALYSIS BY MEANS OF COMPUTER GENERATED INTERACTIVE GRAPHICS Mark Henriquez Energy Analysis Group Lawrence Berkeley Laboratory In an age where resolution of complex technical ques tions is characterized by the use of large data sets, informational display in the term of interactive comp uter graphics has become an increasingly valuable re search tool. The advantages of cartographic output over alternatives such as a tabular format have increa singly become clear to our research group At the time we were involved in the early stages of a study cond ucted by the Energy Analysis (EAP) Group of LBL, on behalf of the Department of Energy. Our work which is known as Technological Assessment of Solar Energy Characterizations, (TASE) is a project in which we participated with other national laborato ries. It is designed to evaluate the potential of alternative energy systems to displace a given fraction of conventional oil based fuels, identify potential applications and to develop engineering specifications of specific technologies for which potential sites are identified on a county-by-county basis within Federal Region IX. This includes California, Nevada, Arizona and Hawaii. A number of factors are examined in the execution of this task; these include county population and demo graphic trends, ambient air quality, land and water use patterns, to name a few. By displaying base case (existing) and scenario specific (proposed) data sets 405
