一系列综合评估技术已被用于研究各种家用微型发电机的比较性能，这些发电机已被提议作为“低碳”建筑的分散能源。能源，环境影响和成本效益分析方法，采用了“整个系统”的基础上，进行了说明。这个“工具包”的应用说明了三个微型发电机的评价方式：一个微型风力涡轮机;（通用）太阳能光伏阵列;和太阳能热水系统。据估计，所有三个发电机，在适当的位置安装，有能源和碳回报在其寿命内。使用铝制造太阳能热水装置和微型风力涡轮机会对生命周期环境产生重大影响。从社会角度来看，这三种国内微型发电机在目前自由化的英国能源市场上都没有经济吸引力。生产量增加…
A range of integrated appraisal techniques have been utilised to study the comparative performance of various domestic micro-generators that have been proposed as possible decentralised energy resources for ‘low carbon’ buildings. Energy, environmental impact and cost–benefit analysis methods, employed on a ‘whole systems’ basis, are described. The application of this ‘toolkit’ is illustrated by way of the evaluation of three micro-generators: a micro-wind turbine; a (generic) solar photovoltaic array; and a solar hot water system. It is estimated that all three generators, in appropriately sited installations, have energy and carbon paybacks well within their lifetimes. Significant life-cycle environmental impacts are associated with the use of aluminium to fabricate both the solar hot water unit and the micro-wind turbine. All three domestic micro-generators were found to be economically unattractive in the present liberalised British energy markets from a societal perspective. Increased production volu...
