Environmental assessment of the US Department of Energy's solar-thermal-technology program
- eds.
Potential environmental, health, and safety impacts associated with the production and use of solar thermal energy systems (STES) appear in most cases to be negligible, easily mitigated, or site-specific. Occupational health and safety hazards do not differ greatly from those in common industrial practice. Public health issues appear to be limited to concern about accidental or mismanaged off-site releases of heat-transfer/storage fluids, or solid waste from solar ponds, and the possible nuisance of misdirected solar glare. Potential ecological and micrometeorological impacts relate to land requirements of large-scale systems in undeveloped areas, but tend to be site-specific. Uncertainties exist regarding the effect of large-scale loss of habitat on surrounding ecosystems, and the presence of the facility on the behavior of nearby wildlife. Secondary impacts are associated with processing, manufacture, and transport of components and subsystems. These are judged minor. In the short term, when analyzed as a replacement for conventional fossil-fuel systems, STES improve environmental quality by reducing air pollutants; in the long term, STES improve environmental quality by reducing CO/sub 2/ emissions and by minimizing mining, drilling, transport of fuel, and solid waste storage. Solar thermal systems appear no more land-intensive than conventional coal-fired systems. For some industrial applications in metropolitan areas, land requirements are likely to impose a constraint. When suitable locations are available, the primary siting constraint will be institutional barriers associated with land use, zoning, sun rights, and utility interfaces. Available water is a common constraint to any development in the arid west. Depending on the system used and the type of energy produced, STT water requirements can be similar or much less than those of comparable fossil-fueled systems. Reasonable management procedures can mitigate the potential for water quality degradation.
