The document discusses the benefits of hydropower as a renewable energy source in the United States. It notes that hydropower currently provides nearly 70% of the country's renewable electricity but that many dams are outdated and in need of rehabilitation to continue providing clean energy. Investing in improvements to existing dams could allow hydropower to generate more power reliably for decades to come while also creating jobs. The document advocates that hydropower should be part of the national discussion on developing renewable energy sources given its clean, reliable and sustainable characteristics.
