“…They help to maintain healthy ecosystem and balanced climate but most of the world's free owing rivers have been sacri ced for the big hydropower projects. At recent past, Southeast Europe (SEE) has been witnessing a boom in hydropower plant (HPP) construction while as SEE includes global hotspots of aquatic biodiversity, it is expected that this boom will result in a more severe impact on biodiversity than that of other regions (Hudek, et al 2020). Furthermore, Zar et al (2019) expressed that hydropower development will disproportionately impact areas of high freshwater megafauna richness in South America, South and East Asia, and the Balkan region.…”

This paper assess the controversies and tensions being created by the target of ambitious hydropower development plans in the name of climate mitigating energy in the Upper Tista River Basin of Sikkim (India) which is a part of Eastern Himalayan region. However, in the face of climate change, hydropower projects have become a contested developmental paradigm in the Easter Himalayan region of Sikkim. The paper highlights potential issues and conflicts between climate mitigation approaches through hydropower projects and anti hydropower forces of local people. The paper critically examines pre and post hydropower development conflicts and cooperation along Upper Tista river basin. In fact, the region has witnessed that the Hydro Power Project have been undermining environmental and social security over the past years. The study also analyse the different roles of dam affected people, local politicians, NGOs and dam developers in advocating and protesting of the hydropower dam projects in the region. Using an environmental security framework the study critically analyse the environmental risks and impacts being aggravated by combined forces of climate change and hydropower development in upper Tista catchment of Sikkim Himalaya (India).

“…This is most often the case in Europe and North America, where 75% and 69% of the hydropower potential is used, respectively [103]. In Europe, the only major region with considerable potential for the construction of hydropower investments is Southeastern Europe (Balkans) [113]. In Europe, some countries have low water resources and the prospects for the development of hydropower plants are low, such as in Malta and Cyprus [114].…”

“…This is no different in the analyzed four countries; for example, the Danube river basin in Albania and Slovenia (Drin and Sava Rivers) is a naturally valuable area (including numerous endemic aquatic organisms, as well as European endangered freshwater snails and fish, containing 52% and 28% of all species in Europe, respectively [116,117]). The area has a large hydropower potential; construction of 1315 hydropower plants is planned, especially in Serbia and Bosnia and Herzegovina [113]. Overall, 50% of the world's technical hydropower potential is used [103].…”

Hydropower in Europe is playing an increasingly important role as a renewable source of energy. Its share of the final energy consumption varies from country to country, posing different challenges in each. The European Union member states are obliged, according to energy policy, to increase the share of renewable energy. This article presents the challenges related to the development of hydropower in four countries with different shares of domestic electricity production from hydropower plants: Albania (100% share in 2019), Slovenia (25.7%), Poland (1.1%), and Estonia (0.3%). Particular attention is paid to the issues of rational management of water resources in connection to Europe’s energy policy. As a result of the case study analysis, the challenges in the development of hydropower are identified, as well as ways to solve them. In addition, a comprehensive analysis of the impact of social, economic, environmental and climate change factors on the development of hydropower was conducted. At present, whether the assumed goals of the European Union’s energy policy will be achieved is impossible to determine for the whole of Europe. Achieving these goals will be possible only after individual countries prepare comprehensive reports on the topics of renewable energy sources, including hydropower.

“…They are cheaper, efficient and operation and maintenance is simpler than large projects. To increase the number of clean and sustainable energy sources, governments can support initiatives by providing financial subsidies like fixed feed-in or premium tariffs [244]. However, the number of subsidies provided and environmental impact per 1 MW production of energy must be estimated.…”

Dam and powerhouse operation sustainability is a major concern from the hydraulic engineering perspective. Powerhouse operation is one of the main sources of vibrations in the dam structure and hydropower plant; thus, the evaluation of turbine performance at different water pressures is important for determining the sustainability of the dam body. Draft tube turbines run under high pressure and suffer from connection problems, such as vibrations and pressure fluctuation. Reducing the pressure fluctuation and minimizing the principal stress caused by undesired components of water in the draft tube turbine are ongoing problems that must be resolved. Here, we conducted a comprehensive review of studies performed on dams, powerhouses, and turbine vibration, focusing on the vibration of two turbine units: Kaplan and Francis turbine units. The survey covered several aspects of dam types (e.g., rock and concrete dams), powerhouse analysis, turbine vibrations, and the relationship between dam and hydropower plant sustainability and operation. The current review covers the related research on the fluid mechanism in turbine units of hydropower plants, providing a perspective on better control of vibrations. Thus, the risks and failures can be better managed and reduced, which in turn will reduce hydropower plant operation costs and simultaneously increase the economical sustainability. Several research gaps were found, and the literature was assessed to provide more insightful details on the studies surveyed. Numerous future research directions are recommended.
