A few notable H2Oprints from Waterfootprint.org:
And by way of comparison, consider the water used to create energy. Virginia Tech just released a chart tallying the water footprint of different energy sources with some interesting findings.
“Results show that in terms of energy production, biodiesel (soy-based) is the least efficient energy source followed by corn-based ethanol. Natural gas as an energy source is the most water efficient. In terms of power generation, nuclear energy is the least water efficient while hydroelectric power is the most water use efficient system.”
Finally, to learn how you measure up, there are a few different H2O calculators out there. Check here and here. Those watery tracks you leave after climbing out of a swimming pool will never look quite the same.
