Hydropower's Untapped Potential

摘要

At first glance, the potential for hydropower in the U.S. seems limited. Of the country's 84,000 dams, only a small fraction produce hydropower, and the country seems to have an appetite for tearing down dams, not building new ones. But a look under the hood of the hydropower industry reveals a bullish view on the technology and growth of the industry. Powering non-powered dams, upgrading existing turbines to increase efficiency, and embracing small-scale hydro could give an old and established industry new life.
