The Pyramid of New Water Sources

Today is World Water Day and it just so happens that Jerry Yudelson, noted green building authority and author, has released a new conceptual tool to help people understand where water will come from in the future. The tool mimics the popular Pyramid of Conservation used by Minnesota Power and explains water sourcing in ten increasingly expensive and complex steps.

As shown at the base of the pyramid, it’s easy and relatively cheap to use less water. It’s a lot more complicated and expensive to desalinate ocean water for human consumption.
