86% of power is generated by coal
and natural gas
2011 drought stressed power
The population will double by 2060
to 46 million
Demand for water will increase by
80% of Texas is in some form of
The agriculture sector grows 5.3%
Almost 80% of groundwater
withdrawal is for irrigation
Pumping of aquifers already
exceeds recharge in some areas
Texas has ambitious bio-fuel plans

It takes 17 million barrels of
oil to meet Americans’
demand for bottled water
This excludes the cost of
transportation, refrigeration
and recycling
It takes 3 liters of water to
make a 1 liter bottle of water
