随着我国城镇化水平不断加快,城市交通得到快速发展,在给公众带来极大便利的同时,也引发了能源、环境、拥堵等一系列问题。可持续交通作为一种高效能、低排放的发展方式,逐步受到社会的普遍关注。可持续交通的核心在于提高交通运输的能源效率,改善交通运输的能源结构,优化交通运输的发展方式,最终实现交通行业的可持续发展。2014年5月,国务院发布《2014—2015年节能减排低碳发展行动方案》,要求加快绿色循环低碳交通运输体系建设,确保全面完成"十二五"节能减排降碳目标,也为可持续交通的发展指明了方向。 相似文献

能源规划是政府对能源开发利用活动实施指导和管理的重要工具和手段。制定能源规划的重要性在于有利于协调经济、能源和环境的关系,促进能源工业的健康、可持续发展,使其成为我国经济社会可持续发展的坚强支撑。但是在我国,中国特色的能源规划的理论方法和实施的长效机制尚待完善,加上限于制定和实施过程中的许多不确定因素,使得规划往往成了不切实际的设想,被人们讥为“规划,规划,墙上挂挂”。为了发挥能源规划的功能与作用,确实需要研究适应于我国国情的能源规划的制定与实践的理论和机制问题。此文从能源规划与其他规划的关系进行了探讨,期待有更多的论文面世。 相似文献

It is widely recognised that access to and supply of modern energy play a key role in poverty alleviation and sustainable development. The emerging concept of energisation seems to capture this idea, and if implemented in its full complexity it should have multiple beneficial effects. To demonstrate this, an economic model is developed for an urban developmental context, drawing on the theory of urban ecosystems and illustrating energy and waste production and consumption issues with current South African data sets. This new understanding of the concept of energisation is then integrated into a local government energy planning process, by means of a checklist for energy planners, covering 18 aspects that between them affect all 7 identifiable tiers of the energy service supply network. A 6-step structured approach is proposed for integrating sustainable energisation into the first four phases of the advanced local energy planning (ALEP) tool. 相似文献

结合"十二五"某城市群区域规划,选取规划中提出的碳强度、能耗强度两项指标为约束条件,构建了一种基于经济、社会、环境可持续发展的城市群低碳优化模型。优化结果表明:在满足碳强度、碳汇面积、能耗强度、GDP等条件下,城市群"十二五"末期碳排放总量为3.70×107t,较2010年区域碳强度下降了35.56%,能耗强度下降了40.49%,城市群"核心区"碳强度下降了36.77%,能耗强度下降了37.99%,不仅满足国家《"十二五"控制温室气体排放工作方案》中提出2015年的碳强度、能耗强度较2010年分别降低17.00%和16.00%的要求,而且满足该城市群区域规划中提出2015年的碳强度、能耗强度较2010年分别降低18.00%和20.00%的目标,该优化方案为城市群的低碳发展提供了一定的决策空间。 相似文献

Sustainable development of the new energy industry requires continuous input from professional talents. The new energy industry will continue to grow in importance, and the characteristics of the necessary cross-discipline talents that will promote its development are becoming more and more defined. This article puts forward an analysis model starting with the addition of talents carriers subdivided by specialties, and takes this subdivision as a starting point with the purpose of maximizing talents selection throughout the entire nation. First of all, we define each talent as a specific vector. Then a clustering algorithm is used to perform an analysis and the new energy talents database is created. Finally, we use an algorithm based on graph theory and discrete mathematics to calculate the essential value of the talents vector. This value provides a measurement of the importance of the talents. The current talents structure is analyzed in order to clarify understanding of the present situation so as to enable informed planning of targeted training needs and structural adjustments, thus meeting the sustainable development requirements for the new energy industry in China. 相似文献

Despite recent efforts, existing urban energy systems still hardly meet the demands of sustainable development or climate change. Meeting these targets thus will require innovations that use energy much more efficiently and emit far less greenhouse gases. These innovations need to be made on the production as well as the consumption side, on all levels, and need to cover not only technical aspects, but even more service solutions. While many of these solutions still need to be developed, some are already invented but only exist in limited market segments. Opening closed urban planning processes and using open innovation tools can foster bottom-up urban energy system transformation by addressing the interactive ways of decision-making integrating company representatives and citizens. While open innovation tools like (open) innovation workshops or ideas competitions are already used by several companies to find and develop new designs and products, there is yet little experience with energy efficiency ideas and bottom-up changes. Therefore, we analyse energy-efficient ideas generated in three different ideas competitions. We discuss the findings for theory and research on open innovation approaches and bottom-up urban changes. Our results show that there are a vast number of ideas available in the public. Open innovation tools offer advanced possibilities to generate energy-efficient solutions. 相似文献

One of the key factors on which the sustainable development of modern society should be based is the possibility to take advantage of renewable energies. Biomass resources are one of the most common and widespread resources in the world. Their use to produce energy has many advantages, such as the reduction of greenhouse emissions. This paper describes a GIS-based Environmental Decision Support System (EDSS) to define planning and management strategies for the optimal logistics for energy production from woody biomass, such as forest biomass, agricultural scraps and industrial and urban untreated wood residues. The EDSS is characterized by three main levels: the GIS, the database, and the optimization. The optimization module is divided in three sub-modules to face different kinds of decision problems: strategic planning, tactical planning, and operational management. The aim of this article is to describe the strategic planning level in detail. The decision variables are represented by plant capacity and harvested biomass in a specific forest parcel for each slope class, while the objective function is the sum of the costs related to plant installation and maintenance, biomass transportation and collection, minus the benefits coming from the energy sales at the current market price, including the renewable energy certificates. Moreover, the optimization problem is structured through a set of parameters and equations that are able to encompass different energy conversion technologies (pyrolysis, gasification or combustion) in the system. A case study on the Liguria Region (Savona Province) is presented and results are discussed. 相似文献

Urban development has an important influence on the energy consumption of transportation. To develop public transportation is one of the important ways to decrease the energy consumption of urban transportation. It is very urgent to upgrade technology to reduce the energy consumption and emissions of the vehicles constantly. The popularization of hydrogen fuel cell vehicles is the trend of the future automobile industry, which can effectively reduce traffic energy consumption and alleviate urban pollution. This article analyzes the impact of urban development on public transport and private transportation energy consumption from 2013 to 2015; and uses hydrogen fuel cell vehicles alternatives in urban public transport as a scenario. It shows that urban economic development can effectively reduce public transport. Population growth will increase greatly energy consumption of public transport, while larger cities with reasonable spatial density can reduce traffic energy consumption. Moreover, hydrogen fuel cell vehicles can effectively reduce the energy consumption and pollution emissions of urban transportation during operating. Based on the above conclusions, this article will eventually provide targeted recommendations for the development of Chinese cities, public transport, and hydrogen fuel cell vehicles. 相似文献
