In common with other major economic centres in China, Shanghai's energy consumption has been increasing rapidly to support the high growth rate of its economy. To achieve rational, efficient and clean use of energy, together with improved environmental quality within the city, the Shanghai municipal government has decided to expand the supply and utilization of natural gas. Shanghai plans to increase the share of natural gas in its primary energy mix to 7 per cent by 2010, up from 3 per cent in 2005. This increase in natural gas demand has to be matched with a corresponding increase in supply. To date, the Shanghai region has relied on offshore extracted natural gas but this supply is limited due to the size of the reserves. Since 2005, the West-East pipeline has provided an alternative for Shanghai but demands from other regions could reduce the potential for expanding supplies from that source. Since domestic production will not be sufficient to meet demand in the near future, Shanghai is building a liquefied natural gas (LNG) regasification terminal at the Yangshan deep-water port that would allow an additional supply of more than 3 billion cubic meters per year of natural gas. Malaysia has already committed to supply LNG to the Shanghai terminal at a price that is significantly higher than the wholesale "city-gate" price for natural gas transported via pipeline, but still lower than the gas price to end-use consumers. The presence of both an LNG terminal and a transmission pipeline that connects Shanghai to domestic gas-producing regions will create gas-on-gas competition. This study assesses the benefits of introducing such competition to one of China's most advanced cities under various scenarios for demand growth. In this paper, the impact of imported LNG on market concentration in Shanghai's gas market will be analysed using the Herfindahl-Hirschmann index (HHI) and the residual supply index (RSI). Our results show that Shanghai remains a supply-constrained

Full Text available. As some of the most rapidly urbanizing places in the world, China's cities have a unique relationship with global climate change. The economies found in Chinese cities are extremely resource and energy intensive; as a result, they produce significant levels of greenhouse gas (GHG) emissions. This article provides comprehensive and detailed emissions inventories for Shanghai, Beijing, and Tianjin, which were found to be responsible for 12.8, 10.7, and 11.9 tonnes of carbon dioxide equivalent per capita (t CO2-eq/capita), respectively, in 2006. The majority of emissions were from electricity production, heating and industrial fuel use, and ground transportation. The prevalence of coal in the energy supply mix (including up to 98% in Tianjin) was a fundamental cause of high energy emissions. Non-energy emissions from industrial processes were also significant, including emissions from cement and steel production. The GHG inventories for Shanghai, Beijing, and Tianjin point to sectors requiring the most attention in terms of low-carbon growth. Compared to ten other global cities, Chinese cities are among the highest per capita emitters, alluding to the important challenge China faces of reducing emissions while improving the quality of life for urban residents. Accordingly, this article concludes with a discussion of the opportunities and issues concerning low-carbon growth in China, including the potential for renewable energy and the difficulties associated with emissions relocation and policy adoption.

Hoversten, Shanna, "Electric Vehicles: Market Opportunities in China" (2010). CMC Senior Theses. Paper 1. http://scholarship.claremont.edu/cmc_theses/1 Abstract Electric vehicles (EVs) offer an exciting opportunity in China both in terms of the potential to build a domestic manufacturing base and the potential to create a strong domestic market for the product. The Chinese nation stands to benefit from both supply-side and demand-side promotion due to the economic stimulus from EV manufacturing and export, the environmental benefits of reduced air pollution and reduced greenhouse gas emissions, and the energy security benefits of transitioning away from foreign oil dependence. The Chinese have several advantages when it comes to stimulating EV industry development and EV deployment, including: leadership in battery technology, great potential for cost competitiveness, an enormous and emerging number of new car buyers, and high level government support. Yet a number of challenges must be taken into account as well, including: shortfalls in overall automobile R&D spending, consumer concerns about Chinese cars' safety and reliability, enhancing the appeal of the Chinese brand, and heavy national infrastructure demands. This paper will seek to examine the opportunities and challenges associated with EV deployment in China and identify industry actions and policy measures to facilitate the process.

Local level actions can also assist in proving the effectiveness of new policies or initiatives by demonstrating them at a smaller scale. It is often also shown that innovative policies or practices can be relatively easily implemented at the local level because of the reduced scale and the possibility of exemption from some national legislative bureaucracy. Following success at the local level, the pilot policies or practices could be replicated to other localities or expanded to a national program. For example, China's Top-1000 Enterprise Program was drawn upon the successful experience from a demonstration program implemented in two steel mills in Shandong province that was modeled after the voluntary agreements program in The Netherlands (Price et al. 2003)."

With rapid economy growth, building energy consumption in China has been gradually increased. The energy consumption and indoor environmental quality of 51 office buildings in Hainan Province, a hot and humid area, were studied through collection of verified data in site visits and field tests. The result revealed that, electricity accounted for 99.79% of the total energy consumption, natural gas 0.17%, and diesel 0.04%. The air conditioning dominated the energy use with a share of 43.18%, equipment in the particular areas 26.90%, equipment in the office rooms 11.95%, lighting system 8.67%, general service system 7.57%, and miscellaneous items 1.73%. Statistical method including six indicators obtained the energy consumption benchmark with upper limit of 98.31 kW·h/m2 and lower limit of 55.26 kW·h/m2. According to ASHRAE standard (comfortable standard) and GB/T 18883-2002 (acceptable standard), the indoor environmental quality of 51 sampled office buildings was classified into three ranks: good, normal and bad. With benchmark of building energy consumption combined with indoor environmental quality, it was found that only 3.92% of sampled buildings can be identified as the best performance buildings with low energy consumption and advanced indoor environmental quality, and the buildings classified into normal level accounted for the maximum ratio.

The simulation of land use change is important in environmental impact assessment and land use planning. We assessed the land use scenarios of China in the next 100 years based on the SMLC (surface modelling of land cover change) model and Dyna-CLUE (dynamic conversion of land use and its effects) model. Three SRES scenarios were evaluated: Global Economy (A1FI): lean government, strong globalization; Continental Markets (A2a): lean government, regional culture and economic development; Regional communities (B2a): much government intervention, regional cultural and economic development. Ten land cover types were simulated, which are cultivated land, woodland, grassland, built-up land, water area, wetland, nival area, desert, bare rock and desertification land. The SMLC model was used to calculate changes in area for each land use types in the future at country level while the spatially explicit land use model Dyna-CLUE was used to simulate land use pattern at 2 km2 resolution based on the country level areas demands for each land cover type. The results show that the cultivated land would decrease in all of the three scenarios, while in the A2a scenario, the cultivated land would decrease with the lowest rate because of the high population growth, high level of market protection and low agricultural efficiency; in the B2a scenario, it would decrease with the highest rate caused by the decreased population numbers and increased crop productivity. The nival area would decrease with the highest rate in the A1FI

[ScienceDirect, via Biblio-SHS] Auteur : Guiwen Liu, Zezhou Wu, Mingming Hu Paru dans : Energy Procedia, Volume 14, 2012, Pages 1925-1930 Abstract Around 30% of the national energy consumption in China can be attributed to buildings, of which one-fifth is consumed within public buildings. In recent time, public buildings have been reckoned as the dominant objects for conducting energy efficient management. In order to obtain valuable information for the assessment of energy consumption status, an investigation was conducted in Chongqing - the youngest, largest and most dynamic municipal in China. A number of public buildings, including 28 governmental office buildings, 15 emporiums and 5 hotels, were selected for the investigation from the aspect of energy cost. Based on the collected data of electricity, water and gas, the characteristics of the energy consumption in each type of the public buildings are discussed, and the energy management in each type of public buildings is compared. 2011 2nd International Conference on Advances in Energy Engineering (ICAEE)
