The present study was undertaken as part of the first application and evaluation of the BREF (Best Available Techniques; BAT Reference Document) Textile Document within the context of the European Union's Integrated Pollution Prevention and Control (IPPC) Directive to a large scale textile mill in Turkey. The BAT requirements for the denim manufacturing textile mill were selected in cooperation with the factory management. Detailed mass balance calculations were conducted to evaluate the overall effect of the selected BAT options. The initial findings indicated that the adoption of the selected BAT options resulted in considerable savings in water and energy consumption in the mill. Besides the installation of flow meters and use of semi-counter current rinsing in the most water-intensive processes, minimization of wash waters in the water softening plant, reuse of the concentrate stream from the reverse osmosis plant and compressor cooling waters provided a 29.5% reduction in the total specific water consumption of the mill, reaching the lower limits suggested by the BREF Textile Document. In terms of energy consumption, use of waste heat from finishing wastewater streams in heating up the wash waters, heat insulation and maintenance applications in addition to BAT measures taken for water minimization reduced specific energy consumption by 9% achieving the limits set by the BREF Textile Document. 相似文献

Turkey occupies a significant position in the global economy and plans to achieve net-zero emissions by 2053. Thus, this study uses the non–linear ARDL (NARDL) framework to analyze the effect of energy intensity (EINT), renewable energy (REN), and economic growth (GDP) on CO2 in Turkey from 1970 to 2021. The results are as follows: (i) The variables have a long-term link; (ii) Over the long-term, a positive (negative) change in EINT increases (decreases) CO2; a positive (negative) change in REN decreases (increases) CO2; and a positive (negative) change in GDP increases (decreases) CO2. (iii) In the short-run, an EINT and GDP negative change decreases CO2. In light of these findings, Turkish policymakers should set energy efficiency standards and support clean energy initiatives, which are some of the practical ways of lowering CO2 and addressing other climate challenges. 相似文献

This paper takes a first step in comparing and synthesising the emerging concept of energy justice with extant ethical consumption literatures as two complementary theoretical approaches to ethics and consumption. To date, theories of ethical consumption and energy justice remain somewhat disconnected, so while they have some areas of potential comparability, these have not yet been fleshed out or developed. To address this lacuna, this paper explores areas where research into ethical consumption might be useful for furthering concepts of energy justice. More specifically the discussion draws on the philosophical foundations, the relationship between consumption and development, and the role of transparency and visibility in reconnecting consumption and production practices as the main areas of overlap in these literatures. The conclusion points to some lessons for emerging energy justice literatures that can be drawn from this task of comparison and synthesis. 相似文献

Abstract This study deals with the estimation of electricity production from hydraulic and thermal sources using the Genetic Algorithm (GA) with time series (TS) approach. Two forms of the mathematical models are developed, of which one is exponential and the second is polynomial. The power form of the Genetic Algorithm-Time Series (GATS) model is used for the thermal electricity production. The polynomial form of the GATS is used for the electricity production from the hydraulic sources. The GATS weighting parameters are obtained by minimizing the Sum of Squared Error (SSE) between observed and estimated electricity production from both sources. Therefore, the fitness function adapted is the minimization of the SSE for use in the GA process. The application of the GATS model is correspondingly presented. Some future scenarios are made to increase the electricity production from hydraulic sources. Variations of the electricity production from thermal and hydraulic energy sources are analyzed. Future prospects of electricity production are dealt with in terms of policy changes. The GATS models are used for making scenarios for future electricity planning policy. Results also show if current trend continues, the thermal electricity production amounts to 75% of the total electricity production, which is undesirable for environmental concerns. Results also shows that if new policy is to move from the thermal to hydraulic electricity production, the hydraulic sources will meet the demand until 2020. 相似文献

Defining better methodologies of accurate predictions of the amount of monthly mean daily global and diffuse solar irradiation exposed is of utmost importance in order to determine the potential for utilizing the solar energy. This study compares and discusses the main methodologies, databases, and software that are used in estimating the solar irradiation to be used for the short- and long-term performances and feasibilities of solar energy systems, especially photovoltaic power plants in Turkey, and addresses the best one to be used to make the most accurate estimations. The comparisons are carried out between the recent methodologies developed by the authors, some models taken from the related literature that are concluded to be better, a widely used database, namely Meteonorm, and a widely used software, namely EU PVGIS. The reference data to develop the methodologies and to make comparison are provided from the State Meteorological Service of Turkey, which is the responsible body in Turkey to make measurements of solar irradiation. The comparisons are based on monthly mean daily values of global and diffuse solar irradiation and are carried out by statistical errors: mean bias error and root mean square error. The results showed that the methodology developed by the authors has shown better performances in estimating the monthly mean daily global and diffuse solar irradiation amount for Turkey. 相似文献

In assessing and deciding the prediction schemes of solar irradiation countrywide, better the accuracy means better the management of energy transition toward renewables. Consequently, the present study is on the development of new models to make the most accurate possible estimations of the global and diffuse solar irradiation based on ground measurements. Such analysis produces the most accurate estimations for the input of solar energy systems. This is utmost significant for deciding the investments on solar energy systems and their design periods. Turkey is a high-potent country whose solar energy market has been growing rapidly. She doesn’t have adequate reliable measurement network and there is no estimation methodology developed for each and every point within its territory. Moreover, installing such a measurement system network doesn’t seem to be economically feasible and technically possible, inter alia. Accordingly, this study defines a methodology to make the most accurate estimations of monthly mean daily solar irradiation on horizontal surface and its diffuse and beam components. For the global and diffuse estimations, new methodologies in linear and quadratic forms are developed, compared, and discussed. The comparison is applied by using mean bias error and root mean square error statistical comparison methods. The measured data values used for modeling and comparisons are provided from the State Meteorological Service of Turkey responsible authority for solar irradiation measurements. The results revealed that the methodologies explained in this study give very high accurate values of total solar irradiation on a horizontal surface and its diffuse component. 相似文献

In line with the global target of reducing climate change and its impact, this study explored the causal relationship between CO2 emissions, modernized agriculture, trade openness, aggregate and disaggregate energy consumption in 14 African countries from 1990–2013 using a panel quantile estimation procedure. The empirical results showed that value addition to agricultural commodities declines CO2 emissions in countries with high pollution levels. The study revealed a positive nexus between CO2 emissions and energy consumption homogeneously distributed across quantiles. Trade openness was found to lower CO2 emissions in countries with lower and higher levels of environmental pollution. While fossil fuel energy consumption was found to exacerbate CO2 emissions, renewable energy consumption confirmed its mitigating effect on environmental pollution. The institution of climate‐smart agricultural options will sustainably increase productivity and income while adapting to climate change by reducing greenhouse gas emissions. Diversification of energy technologies with clean and modern energy sources like renewables avoid the over‐dependence on fossil fuels for agricultural purposes. Trade policies can stimulate flows of technology and investment opportunities for specialization in production and economies of scale. Hence, the consideration of policies that boost agricultural sector productivity and create an efficient market for international trade in Africa will help in improving livelihoods. 相似文献

西藏农村能源消费及环境影响研究 总被引：5，自引：0，他引：5
西藏农村人口现有220多万,占全区总人口80％以上,农村经济落后,城乡差距很大。西藏农村能源资源主要有水力、地热、太阳能、风力、林木和畜粪等,煤炭、石油、天然气等高热值的优质能源很少。在这种经济发展水平及能源资源基础条件下,农村能源消费中高热值的现代能源比重很低,主要以生物质能如薪柴、牛粪、草皮等为主。这种低水平的能源消费结构已经对西藏脆弱的生态环境造成了巨大的破坏,西藏未来的能源发展战略迫切需要改变农村目前的消费结构,应发展太阳能、风能、农村小水电及输入高热值的化石能源替代目前生物质能的消费,减少因能源消费对西藏生态环境的破坏。 相似文献

采用联合国政府间气候变化专门委员会规定的碳排放计算方法,测算了黑龙江省2002-2010年的能源消费碳排放量。运用Kaya分解法,预测了黑龙江省2011—2020年在不同情境下的人均碳排放量。研究表明,2002-2010年黑龙江省能源消费碳排放量以年均8％的速度增长,人均碳排量年均增长率为8．18％。在四种经济增长情境下,黑龙江省2011—2020年人均碳排放量的年均增长率均远远低于2002-2010年,但人均碳排放量仍逐年增长,且GDP增长速度越快,人均碳排放量增长也越快。 相似文献

随着中国经济的发展,我国高化石能源消耗问题也越来越突出。计算了1980--2009年中国人均化石能源足迹,并将其与人均GDP联系起来进行研究,发现在这30年中我国人均化石能源消耗和人均GDP都呈现逐步增长趋势,在用E—G两步法进行协整检验的过程中发现两者存在长期稳定的均衡关系;采用格兰杰因果检验进行进一步的验证分析发现,我国人均化石能源足迹和人均GDP之间互为因果关系,进一步说明我国经济发展对能源消耗尤其是化石能源消耗具有依赖性,且经济发展会进一步刺激化石能源使用的增加。因此,采取节能降耗措施应从调整产业结构和能源消费结构入手,在降低能耗期间我国会出现经济增长放缓的现象。 相似文献

Since the early 1970s, Singapore has enacted a number of measures to tackle traffic congestion, including measures to restrain vehicle ownership. Although Singapore's per capita GDP is comparable to that of OECD countries, the present car-ownership level in Singapore (10 cars per 100 people) is only a fraction of levels in the OECD countries. Traffic flow in this city-State is relatively smooth, even during peak hours. Although the measures taken were aimed primarily at tackling traffic congestion, they have had other positive impacts, such as reducing energy consumption, air pollution and CO2 emissions. This article presents an overview of the transportation measures and initiatives in Singapore, and analyses two of the transport demand management measures in detail: the vehicle restraint measure, in particular the unique vehicle quota system introduced in 1990; and the two road pricing systems, i.e. the area licensing scheme (ALS) that operated from 1974 to 1998, and the electronic road pricing system (ERP) that went into operation in 1998. Energy and environmental impacts are then discussed, and finally factors contributing to the success of these schemes. Although certain conditions are unique to Singapore, the experience shows that substantial energy and environmental benefits can be achieved through managing urban transportation system in an integrated and innovative way. 相似文献
