水力发电被认为是发电成本最低的技术之一，是最传统、清洁、可再生的能源。然而，尽管水力发电提供了环境效益，但它们也会对环境产生负面影响和后果，影响水质和破坏河流生态。我们调查了西班牙西北部四个小型水电站（SPH）的环境影响，通过观察SPH工厂所在的四条河流的水质。分析了水体的物理化学和生物特性，以及河岸生态质量。结果表明，水电站的存在对水体的理化特性影响不显著。除1种植物外，其余植物底栖大型无脊椎动物群落均未发生变化，所有植物的河岸生境总体上为良好或接近自然条件。
Hydropower electricity generation is considered one of the cheapest technologies regarding electricity generation costs, and it is the most traditional, clean, renewable energy source. However, despite the environmental benefits offered by hydropower, they also can have negative impacts and consequences in the environment affecting water quality and disrupting river ecology. We investigated the environmental effects of four small hydropower plants (SPH) in north-west Spain by looking at the water quality of the four river stretches where the SPH plants are located. The physicochemical and biological characteristics of the water streams were analyzed, as well as the riparian ecological quality. Results showed that the presence of the hydropower plants did not significantly influence the physical and chemical characteristics of the water. There were no alterations of the benthic macroinvertebrate community at any of the plants except for one, and the riparian habitat was in general classified as good quality or close to natural conditions for all plants.
