Parabolic-trough solar water heating is a well-proven technology that directly substitutes renewable energy for conventional energy in water heating. Parabolic-trough collectors can also drive absorption cooling systems or other equipment that runs off a thermal load.
There is considerable potential for using these technologies at Federal facilities in the Southwestern United States or other areas with high direct-beam solar radiation. Facilities such as jails, hospitals, and barracks that consistently use large volumes of hot water are particularly good candidates. Use of parabolic-trough systems helps Federal facilities comply with Executive Order 12902’s directive to reduce energy use by 30% by 2005 and advance other efforts to get the Federal government to set a good example in energy use reduction, such as the 1997 Million Solar Roofs Initiative.
