中国新能源汽车行业尚处于起步阶段,在我国汽车市场中所占份额仍然微不足道。在这一阶段,中国新能源汽车的发展表现出三个方面的特点:一是示范意义大于现实意义,二是主要依靠政府部门的各种扶持政策和财政补贴,三是为数不多的新能源汽车集中在北京、上海和广州等少数几个中心城市。发展新能源汽车的政策性理由主要是节约能源和减少污染,而高能耗与重污染正是传统动力汽车显著的负外部性特征。我国的新能源汽车注定具有广阔的发展前景,但其发展过程又注定是独特的。在考虑我国新能源汽车的发展问题时,我国整体的经济发展阶段和能源结构,以及由此决定的我国经济发展战略和能源战略,是我们始终无法回避的前提。 相似文献

新能源汽车技术创新的外部激励路径主要是政策和知识产权保护。政策工具可以快速培育新能源汽车市场,但也养成了新能源汽车企业依赖政策红利,而不是依靠技术创新获得发展的习惯。知识产权保护可以激励新能源汽车企业之间持续地进行公平与有效率的技术创新。我国新能源汽车技术创新外部激励路径转换的重点是在国家和企业层面进行知识产权保护战略规划,为新能源汽车企业技术创新活动提供稳定和可预期激励机制。 相似文献

Changes in the trends in the material composition of domestic and imported automobiles and the increasing cost of landfilling the non-recyclable portion of automobiles (automobile shredder residue or ASR) pose questions about the future of automobile recycling in the United States. In response to these challenges, new and innovative approaches to automobile recycling are being developed. This paper presents the findings of a recent study to examine the impacts of these changes on the life cycle energy consumption of automobiles and on the quantity of waste that must be disposed of. Given the recycle status quo, trends in material composition and the viability of recycling the non-metallic components of the typical automobile are of secondary importance when compared to the energy consumed during the life of the automobile. The energy savings resulting from small changes in the fuel efficiency of a vehicle overshadow potential energy losses associated with the adoption of new and possibly non-recyclable materials. Under status quo conditions, the life cycle energy consumed by the typical automobile is projected to decrease from 599 million Btus in 1992 to 565 million Btus in 2000. Energy consumed during the manufacture of the typical car will increase from about 120 to 140 million Btus between 1992 and 2000, while energy used during vehicle operation will decrease from 520 to 480 million Btus. This study projects that energy saved at the recycle step will increase from 41 million Btus in 1992 to 55 million Btus in 2000. This study also investigated the energy impacts of several potential changes to the recycle status quo, including the adoption of technologies to retrieve the heat value of ASR by incineration and the recycle of some or all thermoplastics in the typical automobile. The study estimates that under optimistic conditions —i.e., the recycling of all thermoplastics and the incineration with heat recovery of all remaining ASR —about 8 million Btus could be saved per automobile —i.e., an increase from about 55 to 63 million Btus. In the more realistic scenario —i.e., the recycling of easy-to-remove thermoplastic components (bumper covers and dash-boards) —the potential energy savings are about 1 million Btus per vehicle. It is estimated that the annual quantity of ASR in the United States could be reduced from about 5 billion pounds to as little as 1 billion pounds of ash if all ASR is incinerated. Alternatively, ASR quantity could be reduced to about 4 billion pounds if all thermoplastics in automobiles are recycled. However, in the case of recycling only thermoplastic bumper covers and dashboards, the quantity of ASR would be reduced by only 0.2 billion pounds. A significant reduction or increase in the size of the ASR waste stream will not in itself have a large impact on the solid waste stream in the United States. 相似文献

Energy Supply Potentials and Needs, and the Environmental Impact of their Use in Sudan 总被引:2,自引:0,他引:2

Sudan is an agricultural country with fertile land, plenty of water resources, livestock, forestry resources, and agricultural residues. An overview of the energy situation in Sudan is introduced with reference to the end uses and regional distribution. Energy sources are divided into two main types; conventional energy (biomass, petroleum products, and electricity); and non-conventional energy (solar, wind, hydro-electricity, etc.). Sudan possesses a relatively high abundance of solar radiation, and moderate wind speeds, hydro, and biomass energy resources. The application of the new and renewable sources of energy available in Sudan is now a major issue in future energy strategic planning and for an alternative to fossil conventional energy. Sudan is an important case study in the context of renewable energy. It has a long history of meeting its energy needs through renewables. Sudan's renewables' portfolio is broad and diverse, due in part to the country's wide range of climates and landscapes. Like many of the African leaders in renewable energy utilization, Sudan has a well-defined commitment to continue research, development, and implementation of new technologies. Sustainable low-carbon energy scenarios for the new century emphasize the untapped potential of renewable resources. Rural areas of Sudan can benefit from this transition. The increased availability of reliable and efficient energy services stimulates new development alternatives. It is concluded that renewable, environmentally friendly, energy must be encouraged, promoted, invested, implemented, and demonstrated by full-scale plants, especially for use in the remote rural areas of Sudan. 相似文献

By concentrating the urban developmental pattern, confining new buildings to areas where technical encroachments on nature have previously taken place, and by utilizing each building site efficiently, considerable advantages can be achieved where the overall goal is to preserve nature and maintain environments. These are the main conclusions from analyses of different alternatives for land use and developmental patterns in three Norwegian urban areas. However, there is relatively little popular support for urban policies in favour of more conservation of land and less use of automobiles. Politicians and bureaucrats are less negative than voters to such a change in urban policies. 相似文献

This paper focuses on the social features of ene rgy production and use in Brazil and discusses the role of the energy policy goals of accessibility, affordability and acceptability in defining a sustainable energy future for the country. The major findings are that social inequalities in Brazil regarding energy use continue to be substantial and important. This can be explained by the fact that, although recent decades have seen significant improvements in energy accessibility all over the country, much more needs to be done to provide affordable, and socially acceptable modern energy carriers to all socio‐economic groups in all regions. 相似文献
