Water-Energy Nexus

Columbia Water Center Cyberseminar Series

Vince Tidwell / Sandia National Laboratories

The need for a coordinated, national, integrative examination of the future sustainability of the nation’s water in the face of changing climate, new energy technologies, agricultural trends, environmental impacts and social values, is in many ways self-evident. The Columbia Water Center’s State of America’s Water: Present and Future project aims to promote both literacy as to subject, but also to engage public and private sector decision makers and the financial community in understanding the dimensions of the issues.

Presenters in the webinar series will address the following:

  1. Past: Assess how the variations in climate, energy development and national/global economics over the last century influenced changes in water use and its valuation across the continental USA
  2. Present: Trends affecting water availability, withdrawal and use of surface water and groundwater by various sectors
  3. Future: Evolution of water use and supply while explicitly considering the capacity expansion of water and energy and urban infrastructure and potential re-allocation of cropping patterns, relative to global climate change, energy and economic scenarios, and prescribed water rights/allocation mechanisms and ecological needs
