The Researches on the Current Energy Consumption and Energy-Saving Potential of Beijing Subway

Energy conservation is a long-term strategic approach of economic development. Subway is a most important way of urban mass transit, the energy consumption of subway accounted for a large part in mass transit. Therefore, retrofitting the subway for energy saving is close to the current policy, it can relieve the energy pressure, so it plays an important role on the sustainable development of economy. This paper conducted a survey of Beijing subway energy consumption, and summed up annual energy consumption data of the Beijing subway lines. Based on this research, this paper shows the energy-saving potential of the Beijing subway. Also it lays the foundation of energy saving transformation for subway.
