  1. Water, Powerand California’s Future Commissioner Karen Douglas, J.D. Water, Energy and Climate Change North Bay Watershed Association 2008 Conference

  2. Common System Issues • Growing Demand • Adequate Supplies • Resource Quality • Infrastructure • Cost • Environmental Protection • Long-term Uncertainty Climate Change forces us to examine the nexus between water & energy!

  3. Intersection of Water-Energy • Electricity Generation • Hydro-electric Generation • Biogas and Other Renewable Generation • Power Plant Cooling • 21 % of California’s Electricity Supply • Water Conveyance, Treatment and Delivery Systems • Natural and Manmade Systems to Move Water to Where it is Demanded • 27 % of total energy demand • Water-related End Uses • 73 % of total energy demand • Water Supplies • Efficiency and Conservation • New Sources: Desalination, Stormwater Capture; Recycled

  4. Water as Power CEC – California’s Generation Mix, 2006

  5. Patterns of Peak Demand

  6. Peak is Important

  7. Energy Demand of New Water Source: Dr. Robert Wilkinson, Environmental Studies Program, University of California, Santa Barbara, and Martha Davis, IEUA

  8. Energy in the Water-Use Cycle

  9. California’s Greenhouse Gas Emissions ARB - Emission Inventory for 2004

  10. Regional Issues and Differences One solution may not be appropriate for everyone.

  11. WET CAT Strategies • Require Recycle Water Programs at all Wastewater Treatment Plants • Develop Urban Runoff and Expanded Stormwater Capture Programs • Promote Greater End Use Water Efficiency through Mandates and Incentives • Lower the Energy Intensity of the California’s Water Systems • Develop Renewable Electric Generation at Water-related Sites

  12. Achieve AB 32 Goals

  13. “Anyone who can solve the problems of water will be worthy of two Nobel Prizes – one for peace and one for science.”John F. Kennedy

  14. Global Warming Solutions Act “The debate is over. We know the science. We see the threat. And we know that the time for action is now.” – Governor Arnold Schwarzenegger Executive Order S-3-05 AB 32 (Nunez), Statutes of 2006
