  1. The 21st Century’s Water/Energy Challenge LB Conference Presented by Debbie Cook October 5, 2006

  2. 10% of California’s electricity production consumed in moving water.

  3. If Ocean Desalination were a car it would be called a Hummer. 5476 3567 3200 2500 2000 1500 950 400 Colorado River Aqueduct West Branch State Water Project East Branch State Water Project Tampa Desal Project Poseidon’s Ocean Desal Groundwater Pumping Recycling GWRS KWh per Acre Foot

  4. Fossil fuels are an energy treasure. = x 500 hours OR x 2 days (36 kWh)

  5. The CEC has taken notice of water as an energy hog. “There is no electricity crisis in California the Water Agencies Can’t Solve - Or Make Worse” California Energy Commission: www.energy.ca.gov

  6. California Energy Commission says: “The 2005 Energy Report assessment of electricity supply and demand concludes that maintaining adequate electricity reserves will be difficult over the next few years.” 7

  7. NG has fundamentally been a local energy resource.

  8. Natural Gas production in North America is in decline.

  9. The LNG outlook is uncertain.

  10. From a presentation to DOE March 27, 2006 by James Jensen

  11. World natural gas reserves are a theoretical US energy source. • Russia: Sahkalin II project • Alaska: Pipeline feasibility • Qatar Moratorium • Iran: “no surplus” • Indonesia in decline • Mexico in decline • Canada in decline • US in decline • Asia getting desperate

  12. Compare it to OC GWRS

  13. “Subsidies for new desalination facilities would most likely not improve the overall economic efficiency of water supply and use because such subsidies would compound the distortion of price signals.” Congressional Budget Office criticizes Subsidies. 21 May, 2005

  14. Energy costs are 4.5¢/KWh Initial projections were $652/AF ($2/Kgal) Updated projections from 2005: $815/AF ($2.5/Kgal) Still not producing as promised We can learn a lot from Tampa’s Experiment! 22

  15. 30 desalination facilities (using a thermal process) Cost $20 billion to build (including $4 billion for O&M) Cost: $1.10/cubic meter or $1356/AF* (based on Saudi gas prices in 2002 of 75¢/Mcf) Saudi Arabia is a better source for cost projections 23 *Oil & Gas Journal, July 29, 2002

  16. It took two years to fill with water. Need 27 per year to keep coastal generators cool. Diamond Valley Lake: 260 billion gallons.

  17. Two billion people rely on fish for their animal protein.

  18. Conservation is good for America!

  19. You know what needs to be done!

  20. Who are you waiting for? We as individual citizens must embrace the culture of conservation so that we change the balance...I am suggesting a National effort in the way we behave and use energy, including autos, homes, work... John Hofmeister, Shell Oil
