As seductive as it is, depleting non-renewable aquifers to grow food is fundamentally unsustainable for the long term, as Saudi Arabia and other nations are finding out. According to a recent article by Lester Brown, in the 1970s the world’s largest oil producer realized it could use oil-drilling technology to tap deep underwater aquifers and—amazingly, [...]

Today, a growing number of scientists argue that global peak oil may be upon us—an argument that would seem to be supported by the increasingly heroic measures oil companies are taking (such as the ultra-deepwater drilling in the Gulf of Mexico) to keep up with global oil demand.

Many underground aquifers and even some surface water stored in lakes and glaciers can indeed be thought of as non-renewable—and thus subject to peak and decline–because they can be depleted faster than the natural recharge rate.

T Boone Pickens, well known for his strong opinions on renewable energy, is hoping that selling water to thirsty cities will be as commercially profitable as he’s found oil to be, and has been investing heavily in purchasing water rights. He opposes a public groundwater management plan that interferes with that.
