在发展中国家实现农村电气化和提供低成本、低排放的技术，需要决策者充分了解所有现有备选办法的成本、适当性和环境资质。虽然成本和适当性往往取决于可观察到的当地考虑因素，但环境考虑因素越来越受到全球关注的影响，而全球关注更难以确定并传达给所有利益攸关方。本研究迭代应用生命周期评估（LCA）3千瓦的社区水电系统位于怀克拉的事情（HKT）在泰国农村村。从摇篮到坟墓的分析模拟了水电方案的建设、运营和寿命结束阶段，涵盖了20年的时间，包括所有相关设备、材料和运输。研究结果列举了HKT水电系统的环境证书，并强调了将环境绩效和LCA本身置于适当背景下的必要性。从最广泛的意义上说，香港电讯水电系统的LCA结果反映了水电LCA文献中报告的一个共同趋势，即较小的水电系统每千瓦时对环境的影响更大-环境表现不佳-比较大的系统。然而，在农村电气化背景下，HKT水电系统比柴油发电机和电网连接替代方案产生更好的环境和财务结果。
Rural electrification and the provision of low cost, low emission technology in developing countries require decision makers to be well informed on the costs, appropriateness and environmental credentials of all available options. While cost and appropriateness are often shaped by observable local considerations, environmental considerations are increasingly influenced by global concerns which are more difficult to identify and convey to all stakeholders.Life cycle assessment is an iterative process used to analyse a product or system. This study iteratively applies life cycle assessment (LCA) to a 3 kW community hydroelectric system located in Huai Kra Thing (HKT) village in rural Thailand. The cradle to grave analysis models the hydropower scheme’s construction, operation and end of life phases over a period of twenty years and includes all relevant equipment, materials and transportation.The study results in the enumeration of the environmental credentials of the HKT hydropower system and highlights the need to place environmental performance, and LCA itself, in a proper context. In the broadest sense, LCA results for the HKT hydropower system are found to reflect a common trend reported in hydropower LCA literature, namely that smaller hydropower systems have a greater environmentally impact per kWh – perform less well environmentally - than larger systems. Placed within a rural electrification context, however, the HKT hydropower system yields better environmental and financial outcomes than diesel generator and grid connection alternatives.
