摘要: Six electricity production systems are evaluated using energy and emergy (Environmental Accounting. Emergy and Environmental Decision Making. New York: Wiley, 1996. 370pp.) accounting techniques, in order to rank their relative thermodynamic and environmental efficiencies. The output/input energy ratio as well as the emergy-based emergy yield ratio (EYR) and environmental loading ratio (ELR) have been jointly used to explore and compare system performances. Generation of CO2 has also been accounted for in order to …
