ABSTRACT:
The environmental data presented in this report are in partial response to the Technology Assessment of Solar Energy (TASE) program. TASE is an assessment of the potential environmental, socioeconomic, and institutional impacts of solar technologies on the national, regional, and local
The results of studies of seven solar thermal energy applications are presented. Five of these are residential applications: space heating--active liquid, space heating--active air, domestic hot water--active, space heating--passive, and space heating and cooling--active liquid. Denver, Colorado, was selected as a representative location for each of the above applications. The remaining two applications produce industrial process heat: a flat-plate collector system producing 50°C - 100°C hot water for a commercial laundry in Indianapolis, Indiana; and a concentrating collector system that could produce 100°C - 300°C process heat adequate to the needs of a pulp mill in Madison, Wisconsin.
For each application, a representative system model and preliminary de-signs of major system elements were established. Then the following data were generated: annual useful energy produced, type and weight of the basic component materials, environmental residuals generated during system operation, and land and water requirements. These data were generalized for other TASE study purposes by expressing them as quantities per 10^15 Btu of useful energy. This report discusses the system characteristics and evaluates the environmental impacts. To allow the reader to estimate system performance at other geographic locations than those studied, insolation and other pertinent data are provided.
There is an almost unlimited variety of solar and conservation elements that can be combined in a system for any application. Also, there are many potential improvements that can be speculated upon, but which were not included in these studies. Therefore the data developed here must be regarded as a "first-cut" at the subject area and it is recommended that more model systems be added for future TASE studies.
For solar space heating and cooling, the direct operating residuals were found to be minimal. Material requirements are high, however, and indirect residuals and impacts may be significant. The latter were not addressed in these studies but will be included in future TASE studies.
The same comments apply to the industrial process heat systems. The potential for the application of solar energy to meet industrial process heat loads appears very favorable. This is because industrial demand is approximately constant throughout the year, competent maintenance and operating personnel would be available as an inherent element of industrial operations, and the systems would be both larger and fewer in number, probably making it easier for the government to develop effective incentives for commercialization.
