语域：neutral 常见场景：能源行业、工程与政策讨论、新闻报道 “hydropower”是中性术语，多用于能源、工程和新闻报道等场合；日常口语里也可以说 water power，但书面表达中用 hydropower 比较常见。
power, flower, tower, and shower all end with the same stressed sound /aʊər/ and rhyme. Hydropower contains the same spelling -ower (/paʊə/), but its main stress is on the first syllable /ˈhaɪ/, so it does not rhyme with those words. Hydro and hydroelectric share the opening sound /ˈhaɪdrəʊ/ with hydropower.
