Water and energy are entwined and battling.
The amount of fresh water consumed for world energy production is on track to double within the next 25 years, the International Energy Agency (IEA) projects.
And even though fracking—high-pressure hydraulic fracturing of underground rock formations for natural gas and oil—might grab headlines, IEA sees its future impact as relatively small.
By far the largest strain on future water resources from the energy system, according to IEA’s forecast, would be due to two lesser noted, but profound trends in the energy world: soaring coal-fired electricity, and the ramping up of biofuel production.
If today’s policies remain in place, the IEA calculates that water consumed for energy production would increase from 66 billion cubic meters (bcm) today to 135 bcm annually by 2035.
That’s an amount equal to the residential water use of every person in the United States over three years, or 90 days’ discharge of the Mississippi River. It…
