Reimagining hydropower in the United States

In this Perspective, we review the clashing narratives around the role of hydropower in the United States' (US) energy future. In doing so, we reveal how hydropower is regarded as a keystone for the renewable energy transition but also viewed as a harmful technology with significant negative environmental and social impacts. These narratives can be seen in the contrasting future renewable energy visions of US government agencies, the hydropower industry, NGOs, and Tribal governments. We review critical lessons learned from past dam- and hydropower-related challenges to reimagine a just energy future for the US that bridges diverse sectors, jurisdictions, and values. We conclude by highlighting some key paths forward that might result in more resilient and adaptive water and energy systems as the country strives to decarbonize.
