ABSTRACT Islam urges Muslims to protect and preserve the environment and not to ruin the nature. This is mentions in the Holy Quran through several verses in many chapters. Therefore, when we talk about renewable energy such as Pico hydro, the green energy or technology suits the teaching of Islam. Allah the All Knowing emphasizes in the Quran the importance of knowledge. Similarly, in many Hadiths the Prophet Muhammad insisted for the Muslims to seek knowledge. Through the Holy Quran, Allah mentions all sort of knowledge such as science and technologies, commerce and economy, health and medicine, laws, history and philosophy, and astronomy. This paper discusses about the basic theories related to Pico hydro power engineering that is proved and mentioned in the Holy Quran. From the observation, it is found that many encounters from research works in the field of hydropower have been approved and produced; but Quran still the best as a reference. Thus, the Quran is clearly preserved by Allah S.W.T. and will be always becomes the main source of knowledge and guidance, as well as the inspiration to all humankind in every aspect of their life, including knowledge such as science and technology: the utilization of the water power for Pico hydro system
