Abstract | Oil consumption and import of China increase very quickly in recent years. Because of vehicle population growing in a tremendous speed, nearly 40% of oil has already used in transportation sector in today's China. Many kinds of alternative fuel vehicles are introduced, demonstrated and used in cities to reduce the traditional gasoline and diesel not only to reduce the regulated emissions, but also to improve the oil security of China. When the Kyoto Protocol became effective in last year, Chinese government and experts began to focus on greenhouse gas (GHG) emissions of alternative vehicle fuels. In order to comprehensively evaluating energy and global warming impact lead by production and utilization of alternative vehicle fuels in China, Well-to-Wheel analysis is used in this paper to quantitatively calculate energy use and GHG emissions of recovery, production, transportation and distribution, and end-use of compressed natural gas (CNG), liquefied petroleum gas (LPG), ethanol, methanol, dimethyl ether (DME) and Fischer-Tropsch diesel (FTD). The feedstock of ethanol includes corn and wheat. The energy use and GHG emissions of alternative vehicle fuels are compared with traditional gasoline and diesel. The results show that CNG and LPG is good choice from energy saving and GHG reduction in China. NG-based and coal-based methanol, DME and F-T diesel have lower lifecycle petroleum consumption than traditional gasoline and diesel, so that they may be an answer to Chinese oil security. The lifecycle total energy use, fossil energy use and GHG emissions of NG-based synthesized fuels are lower than coal-based fuels, but obviously higher than traditional gasoline and diesel, so that utilization of them will lead to potential pressure to China GHG reduction responsibility. The GHG emissions performance of China ethanol fuel is not as good as U.S. ethanol. The main reason is abuse of agriculture chemical in corn farming, especial the nitrogenous fertilizer, which is caused great N20 emission |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
