The purpose of this report is to present and prioritize the major environmental issues associated with the further development of solar energy as a source of process heat in the industrial and agricultural sectors. To provide a background for this environmental analysis, the basic concepts and technologies of solar process heating are reviewed. The potential effects of these applications of solar energy on the full range of environmental concerns are then discussed in terms of both their relative significance and possible solutions. The environmental impacts of the solar energy producing technologies are discussed. Finally, an environmental work plan is presented, listing research and development proposals and a National Environmental Policy Act (NEPA) document work plan which might help clarify and/or alleviate specific environmental and safety problems.
