In the Water-Energy Nexus session panelists will discuss threats to our nation’s water resources, interagency coordination to address national outcomes for water and energy, advances in offshore renewable energy development, including the challenges and tradeoffs facing the country.

For these reasons, coupled with a changing climate and extreme weather events, there is a need for an integrated approach to science and services for water resources in the energy sector.
