摘要

Industrial energy consumption tracks industrial production: globally, the largest industrial output is from China, followed by the United States, and then by Germany. Some 45–50% of China’s energy consumption is used in industry; for the US it is 28%. Analysis from Germany indicates significant variation across industrial sectors in value added per MJ of energy used. There is significant potential for increased energy efficiencyEfficiency (Energy Efficiency) and productivity. Industrial ecology provides a systematic view of opportunities for improvement, with consideration of dematerialization, recycling, and industrial symbiosis.
