  • In the past, most discussions of financing needs for energy and water projects assumed that conventional technology will be used. In addition, these discussions assumed energy and water to be separate systems that can be analyzed, designed, and built independently.
  • Now, the interconnections between the separate energy and water systems are being recognized, with significant efforts underway to find mutual efficiencies and new technologies. The ASE Watergy program is one of the leading examples. These are essential and valuable programs; but, as the next slide shows, much more needs to done.

    1. 1. Water, Energy, and Sustainability
    2. 2. In a biotech world, water networks are abigger deal than bit streams. You’re notmade out of digital bits – like all livingthings, you are made mostly of water.So that’s where you sensibly place yourhigh tech investments. Bruce Sterling
    3. 3. Water is: • An Economic Issue • An Environmental Issue • An Aesthetic Issue • A Food Issue • A Health Issue • A Climate Issue • A Security Issue
    4. 4. Our Bottom Line: During the next 10 years, many countries importantto the United States will experience water problems – shortages, poorwater quality, or floods -- that will risk instability and state failure,increase regional tensions, and distract them from working with theUnited States on important US policy objectives. Between now and2040, fresh water availability will not keep up with demand absentmore effective management of water resources. Water problems willhinder the ability of key countries to produce food and generateenergy, posing a risk to global food markets and hobbling economicgrowth. As a result of demographic and economic developmentpressures, North Africa, the Middle East, and South Asia will facemajor challenges coping with water problems.
