We Are Moving Towards More Energy-Intensive Water• Stricter water/wastewater treatmentstandards• Deep aquifer production• Desalination– Worldwide capacity to double by 2025– Middle East, London, San Diego, TX• Long-haul pipelines and inter-basin transfer– China, India, Texas• Desalination plus long-haul transfer Economist, June 7, 2008Michael E.

We Are Moving Towards More Water-IntensiveEnergy• Nuclear power, Solar CSP– Note: also choosing water-lean energy forms• Solar PV, wind, natural gas• Future transportation fuels are especially thirsty– Unconventional fossil fuels (2-4x worse)– Natural Gas (better to 1-2x worse)– Electricity (2-3x worse)• Good with wind/solar PV, worse with nuclear– Hydrogen (1-500x worse)• Good with wind/solar PV, worse with nuclear– Biofuels (1-1000x worse)[Source: King & Webber, 2009]Michael E.
