- 2. Key Take-Aways Water is the next big (green) thing International experience and technology can be adapted here Major new opportunities: owners, designers, facility managers, entrepreneurs and ©2011 Yudelson Associates contractors
- 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 battleground Yudelson Associate © 2011

- 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 issue Yudelson Associate © 2011
- 10. Water Conservation vs. Water Efficiency Yudelson 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) California Yudelson 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
- 14. Your Personal Water Conservation Audit © 2010 Yudelson Associates
- 15. Australia 20 million people Most live near the coasts Except for tropics, country is quite dry Global warming has moved storm tracks south ©2011 Yudelson Associates Biggest drought in 117-year recorded history since 2005

- 18. Australia: Lessons Learned In a crisis, everything’s on the table Easier to do big things politically System favors (big) long-term solutions Don’t neglect public participation New technology can be mandated in crisis Exotic solutions can be tried and evaluated Yudelson Associate Murray-Darling — Australia’s Largest River © 2011

- 23. Where Does This Leave Us? A very dynamic future: much opportunity New technologies, systems, approaches New products coming to market constantly Larger questions? What about environment? ©2011 Yudelson Associates
- 24. Opportunities? “Green plumbing” Building fixture retrofits NEWater reuse/recycling systems New specialties Whole systems engineer Use of less-than- potable sources will Yudelson Associate increase © 2011
- 25. The Future is Green, But… If we want to score, we run to where the ball is headed, not to where it is. Ask yourself: how green (and how blue) will the built environment be in 2015? Spain Wins FIFA World Cup 2010 How can I participate in ©2011 Yudelson Associates the water revolution?
