Library Energy Conservation Benchmarks presents detailed data largely from academic and public libraries about their efforts to conserve energy and reduce their greenhouse gas imprint. The report covers a broad range of energy use and environmental issues including but not restricted to: architectural and structural changes to preserve energy, better use of insulation, current and planned use of alternative energy sources such as wind, solar and geothermal; management of library-operated vehicles; use of energy audits and energy-efficient computer workstation management, among other issues.
