Efficient hydroenergy conversion technologies, challenges, and policy implication

Hydroenergy is one of the cleanest and zero-emission renewable energy sources on the planet. This study presents a state-of-the-art review on efficient technologies for energy production from hydroenergy resources. The global renewable energy production scenario from 1990 to 2017 have been analyzed for the potential of hydroenergy throughout the world. Also, traditional techniques and recently developed advanced approaches for hydroenergy production are discussed in detail in this chapter. One of the key features to analyze is the technical challenges currently facing this sector, and possible solutions have also been analyzed. Furthermore, techno-economic analysis and socio-environmental effects of hydroenergy applications have been presented by reviewing the recent works and articles. Finally, the clean energy policy implications and recommendations to endorse the hydroenergy application in different regions in the world have been summarized and presented in this work. The study concluded that hydroenergy resources have great potential for future clean energy production to meet increasing energy demand as well as maintain a sustainable environment for future generations.
