URGENCY VISION SUCCESS VALUE DISTINCTION
The Water / Energy NexusAvoiding limits on our energy future
URGENCY
v v
The Water / Energy Nexus
Water use and availability will soon limit emerging opportunities for energy independence and economic development.
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
