  • 3. Why Water? Water: 21st Century oil Freshwater supply limited Population/urban growth: large water footprint Global warming hits water Major droughts since 2006 Water efficiency leads to conservation outcomes©2011 Yudelson Associates
  • 4. Water Is the Oil of the 21st Century Resource conflicts Existing water sources fully allocated Next urban/rural battlegroundYudelson Associate© 2011
  • 5. Water is the Oil of the 21st CenturyYudelson Associate© 2011

  • 8. © 2011Yudelson Associate Water Footprint
  • 9. Global Warming Much of world summer water supply from snowmelt Changes in climate = smaller snowpack, larger spring runoff, greater flooding, reduced summer stream flows Water pricing for conservation will be huge issueYudelson Associate© 2011
  • 10. Water Conservation vs. Water EfficiencyYudelson Associate© 2011
  • 11. Water/Energy Nexus Hydropower still important Water supply <=> energy use Energy supply <=> water use By 2020s: Not enough water for energy, or energy for water!©2011 Yudelson Associates Lake Lanier, Atlanta, GA
  • 12. Major Droughts Since 2006 In the U.S. In Australia Atlanta Every major city South Texas (Austin/San • Murray-Darling basin Antonio) CaliforniaYudelson Associate Murray-Darling, Australia’s Largest River© 2011
  • 13. Water Conservation vs. Water Efficiency Conservation means less total use But, efficiency does not guarantee conservation Behavior modification equally important Some water conservation: unintended consequences©2011 Yudelson Associates San Francisco: $14 million for bleach
