Hydropower Dams, Environment and Politics
Renewable energy sources are vital to fulfill the high demands of energy in the present world. The common renewable energy sources are wind, hydropower, nuclear and biomass. However, hydropower is considered the most flexible and consistent renewable energy source because it is comparatively cheaper and more available. Besides hydroelectricity production, hydropower dams can also be useful for irrigation. Though hydropower energy is considered as green energy due to its less carbon emission, still other environmental impacts of hydropower dams are many. Hydropower dams are built based on political ground. Research into the politics of building hydropower dams and environment remains underdeveloped in many ways. Thus, this paper focuses on the issues of politics of building hydropower dams and its impacts on environment. This paper has critically reviewed the extensive literature to examine the argument and counter argument. This paper argues that the building hydropower dams on international river for renewable energy has political as well as environmental impacts. Most of the literature argued that hydropower dams provide renewable energy which produces less carbon emission, but it is argued in this paper that hydropower dams have huge political and environmental impacts nationally and internationally. Displacement of the people and dispute for water distribution among countries due to the building hydropower dams are also considered to be significant for discussion in this paper. Thus, the paper critically examines the impacts and role of hydropower dams on environment, international relations and politics.
