Embodied energy use in China's infrastructure investment from 1992 to 2007: calculation and policy implications.

Liu H, Xi Y, Ren B, Zhou H - ScientificWorldJournal (2012)

Bottom Line: We also use the structure decomposition model to analyze the factors impacting the embodied energy use in infrastructure investment for the same time period.The results show that embodied energy use in infrastructure investment accounted for a significant proportion of China's total energy use with an increasing trend and reflect that improper infrastructure investment represents inefficient use of energy and other resources.Some quantitative information is provided for further determining the low carbon development potentials of China's economy.

ABSTRACT
Infrastructure has become an important topic in a variety of areas of the policy debate, including energy saving and climate change. In this paper, we use an energy input-output model to evaluate the amounts of China's embodied energy use in infrastructure investment from 1992 to 2007. We also use the structure decomposition model to analyze the factors impacting the embodied energy use in infrastructure investment for the same time period. The results show that embodied energy use in infrastructure investment accounted for a significant proportion of China's total energy use with an increasing trend and reflect that improper infrastructure investment represents inefficient use of energy and other resources. Some quantitative information is provided for further determining the low carbon development potentials of China's economy.

fig2: China's embodied energy use in infrastructure investment in absolute term (million tons of standard coal).

Mentions: The overall results of China's embodied energy use in infrastructure investment are reported in Figures 2 and 3, in absolute term and percentage of China's total energy use, respectively. China's fast-increasing infrastructure investment, with annual growth rate 25% from 1992 to 2007, has led to accelerated requirements of energy. As shown in Figure 2, China's embodied energy use in infrastructure investment increased from 78 million tons of standard coal in 1992 to 354 tons of standard coal in 2007. The results also show that the embodied energy use in infrastructure investment has increased rapidly from 2002 to 2007. The embodied energy use in infrastructure investment growth from 2002 to 2007 was about 140 million tons of standard coal, which is more than the growth of embodied energy use in infrastructure investment from 1992 to 2002.
