URGENCY
v v
The Water / Energy Nexus
Water use and availability will limit our energy choices without substantial efficiency improvements.
Shale Gas?
3 MM gal /well & quality concerns
Carbon sequestration?
25% greater water usage
Biofuels?
Doubling of water consumption for fuels

VISION
v v
The Water / Energy Nexus
Provide water with consistent quantity and quality to avoid limiting our energy choices.
Facing challenges like too little water, too much water, & poor water quality
