Exergy-based resource accounting for China

摘要: The resource accounting of the Chinese economy in 2000 is presented based on exergy as a unified quantifier for natural resources. Major resources entering economic production include sunlight, wind power, tidal wave geothermal nuclear biomass, straw, hydropower, coal, oil, gas, wood, ores, agricultural and aquatic products. conversion embracing paper, food, iron steel, nonferrous metal, chemical other industries well transportation, household commerce sectors are illustrated. efficiencies thermal procedures including lighting, mechanical work, space heating, cooking, water heating process also estimated. total input was 64.76 EJ, which 51.0 GJ/cap, whereas output contained 12.8 EJ or 10.1 indicating efficiency 20%. present study illustrates possibilities increasing different provides theoretical foundation policymakers establishing effective regulatory mechanism production.
