An investigation into the present situation and characteristics of china's energy consumption

The present situation of China's energy consumption and its composition in the past decade is introduced in this paper. The characteristics of energy consumption in China are: energy sources are mainly supplied domestically; coal predominates in the composition of energy consumption (average 725%); industrial energy consumption takes the largest proportion of the final energy consumption (average 65.6%); the utilization efficiency of energy is low; serious environmental pollution is caused by coal combustion. It is necessary to conduct technology innovation for energy conservation because of the low efficiency utilization of energy by appliances and the backwardness of industrial technologies. China must carry out continuously the principle ‘lay equal stress on development and conservation and give priority to conservation in the near future’ with the idea that the economy will have a high growth rate.     

影响全国与北京工业能源消费的关键要素对比分析

全国能源强度2002年开始上升,北京能源强度却一直呈现下降态势;这不仅和北京第三产业快速发展相关,而且北京工业能源强度也保持了下降趋势。基于对数均值迪氏指数分解法,将能源消费分解成规模效应、结构效应和效率效应,对1998～2006年的北京及全国工业能源消费量进行了分解及对比分析。研究表明,效率效应对全国工业能源消费下降起到了比较显著的作用,而结构效应和效率效应共同促使北京的能源消费降低。与全国相比,北京大力促进高科技产业的发展,控制黑色金属冶炼及压延加工业、化学工业等高耗能工业的发展,是其工业能源强度迅速降低的一个重要原因。最后,分析了北京能源强度快速下降对全国的启示,并提出了全国能源消费进一步降低的政策建议。

Global overview for energy use of the world economy: Household-consumption-based accounting based on the world input-output database (WIOD)

Globalization has integrated nations into a world economy. Based on the world input-output database (WIOD), this paper explored the energy use of the world economy under a household-consumption-based MRIO (multi-region input-output) accounting scheme. Pertaining to normative economics, the household-consumption-based MRIO accounting scheme corresponds to the value judgement of household consumption being the ultimate driver of the economy, which complements existing accounting methods based on different viewpoints. The energy use associated with the internationally traded products is calculated to be around one-fifth of the global total energy consumption. For China as the largest exporter and also the biggest deficit economy in terms of energy use, its trade imbalance is nearly the summation of that of the United States, the United Kingdom, Japan and Germany. Energy self-sufficiency rates by supply and by demand are respectively proposed. While the United States economy as the largest importer maintains the majority of the energy welfare denoted by the onsite energy use at home, China exports large quantities of energy use abroad. For economies like Germany, South Korea and Taiwan, they could be regarded as hubs that export a considerable amount of energy use abroad and absorb massive energy use from outside simultaneously. For sustainable use of energy resources, economies are suggested to carefully identify their roles in the global trading network of energy use.     

China's natural gas: Resources,production and its impacts

In order to achieve energy consumption targets, and subsequently reduce carbon emissions, China is working on energy strategies and policies aimed at actively increasing the consumption of natural gas—the lowest carbon energy of the fossil fuels, and to enhance the proportion of gas in total primary energy consumption. To do this, it is a necessary prerequisite that China must have access to adequate gas resources and production to meet demand. This paper shows that the availability of domestic gas resources are overestimated by China's authorities due to differences in classification and definitions of gas resources/reserves between China and those accepted internationally. Based on official gas resource figures, China's gas production remains low with respect to the projected demand, and will only be 164.6 bcm in 2020, far lower than the 375 bcm of forecast demand. The gap between gas production and demand will reach 210.4 bcm by 2020. Existing plans for the importation of gas and the development of unconventional gas will not close this gap in the next 10 years, and this situation will therefore present a severe challenge to China's gas security, achievement of targets in improving energy consumption structure and reducing carbon emissions.     

Analysis of China's energy utilization for 2007

China is the world's second-largest energy producer and consumer, so that it is very necessary to analyze China's energy situation for saving energy consumption and reducing GHG emission. Energy flow chart is taken as a useful tool for sorting out and displaying energy statistics data. Energy statistics data is the premise and foundation for analyzing energy situation. However, there exit many differences between China and foreign energy balance. Based on the international criterion of energy balance and some advices given by related experts, the author properly adjusts China's energy balance. And the purpose of this paper is to draft China's energy flow chart for 2007, which is used to study the characteristics of energy production and consumption in China. We find that: (1) coal is the main energy in China, which accounted for 73.2% of total energy supply in 2007; (2) thermal power accounted for 83.2% of the total electricity supply, and 78.43% thermal power was based on coal; (3) in 2007, the secondary industrial sector consumed about 69.93% of energy; (4) China's energy utilization efficiency was about 33.23% in 2007.
