太阳能产业的朝阳气质--从新富施正荣谈起

《中共中央关于制定国民经济和社会发展第十一个五年规划的建议》明确提出，要“加快发展风能、太阳能、生物质能等可再生能源”。但是可再生能源产业在我国仍然处于起步阶段。     

太阳能产业发展正当时

煤、石油、天然气,包括水底甲烷水合物从根本上来说都源自于太阳能.与化石能源不同的是,太阳能是一种可再生能源.这种可再生生在能源危机频出的今天,其意义更为深远.随着产业化程度不断提升,太阳能产业也迎来了其发展的大好时机.     

A world model of the pulp and paper industry: Demand,energy consumption and emission scenarios to 2030

This article introduces a bottom-up global model of the pulp and paper sector (PULPSIM) with a focus on energy consumption and carbon emissions. It is an annual recursive simulation behavioural model with a 2030 time horizon incorporating several technological details of the industry for 47 world regions. The long time horizon and the modular structure allow the model users to assess the effects of different environmental, energy and climate policies in a scenario comparison setup. In addition to the business as usual developments of the sector, a climate commitment scenario has been analysed, in which the impacts of changing forest management practices are also included. The climate scenario results reveal that there is a significant carbon reduction potential in the pulp and paper making, showing a number of specific features: the central role of the fibrous resource inputs and the potential impact of increased waste wood and black liquor based heat generation.     

Possibilities of solar energy utilization

Geographic and economic aspects of solar energy are linked with the various physical and chemical methods of solar energy conversion to heat, electricity, and endothermal chemical reactions. Principles of the conversion methods are summarized and the efficiencies of various methods reviewed briefly. Methods of concentrating the solar energy are described.     

Empirical analysis of energy management in Danish industry

In this article we examine energy-management practice in the Danish manufacturing industry. The paper addresses the following: To what extent is energy management put into practice in Danish industry? From which sources does Danish industry obtain its information about making improvements in energy management? Based upon the results of a telephone survey covering 304 Danish industrial firms and by use of our definition of the minimum requirements for energy management, we concluded that between 3% and 14% practice energy management. Inspiration to manage energy comes from many different sources, but the electricity utilities emerge as the main source of inspiration. This leads to a presentation of a statistical model synthesising two types of energy management and two potential avenues that can lead to improved energy management. One-size-fits-all is not appropriate when giving incentives for firms to practice improved energy management. Possible variations between industrial sectors are addressed.     

走进核能的世界 了解中国的核电

<正>人类从钻木取火到工业革命再到信息时代,能源的使用从木材到煤炭与石油再到电磁能与核能,每次能源应用的变革都推动了人类社会加速发展,同时能源问题也成为关系到国计民生乃至国家安全的重大课题。传统的煤炭和石油在我国的能源结构中占据了绝对主导的位置,但随着我国居民生活水平的提高使这些传统能源的消耗不断增加,进而更加凸显出我国能源结构不合理的基本国情和"软肋"。走一条清洁、高效、安全、可持续的能源发展之路,是向污染宣战、加强生态环保的节能减排措施,促进大气质量改善的必然选择。自上世纪九十年代初开始,我国大陆     

配额制搅热可再生能源市场

Minimizing greenhouse gas emissions through the application of solar thermal energy in industrial processes

The analysis of industrial energy usage indicates that low temperature processes (20 ≈ 200 °C) are used in nearly all industrial sectors. In principle there is the potential to use solar thermal energy in these lower temperature processes thus, reducing the environmental impact of burning fossil fuels. Using the model of an Austrian dairy plant, this research investigated the potential for, and the economic viability of, using solar energy heat processes in industry.Some industrial sectors such as food, chemistry, plastic processing, textile industry, building materials industry and business establishments can be identified as potential sectors for the application of solar energy heat processes. When assessing the (economic) feasibility of solar thermal energy, the investigation of these industries’ energy systems has to focus on an integrated analysis of cooling and heating demands and to take into account competing technologies. Amongst these are heat integration, cogeneration, new technologies and heat pumps. Pinch analysis was used to investigate industrial energy systems and heat integration possibilities and proved to be a viable tool. Working from the basis of energy balances, Sankey diagrams, pinch analysis and environmental cost accounting, a newly developed investigation tool was applied in the case study of an Austrian dairy plant. This enabled a fast optimization of the system. Two different options for the integration of solar thermal energy into the production line were calculated, option 1 with a solar field of 1000 m² and option 2 with a solar field of 1500 m². Natural gas savings of 85,000 for option 1 and 109,000 m³/a for option 2 can be achieved, resulting in a reduction of 170 tons of CO₂ per year, or 218 tons for options 1 and 2 respectively. Based upon option 1, return on investment is realised after less than three years of implementation. This research thus, indicates promising technical and economical feasibility of using solar thermal energy for industrial processes and provides an important step towards sustainable zero emission production in industry.
