Denver Water and Xcel Energy have teamed up with NAIOP Colorado, the Commercial Real Estate Development Association, in pursuit of a common goal: to make office buildings, warehouses and other commercial real estate in the Denver-metro area more energy and water-efficient. This innovative new partnership between three of Colorado's leading organizations serves as an example of how water and energy utilities can team up and leverage their resources for effective water and energy conservation.

Professors at the University of Arizona's department of civil engineering and engineering mechanics were recently awarded a $2 million grant from the National Science Foundation to research energy water reuse and supply systems. In addition to studying the feasibility of reusing wastewater to me growing water demands in arid regions, the researchers intend to develop a computer model for water managers who are grappling with the problem of using less energy while meeting increased demand for water.

The Groundwater Protection Council is hosting what will likely be a great event for all of those water-energy wonks out there: The Water/Energy Sustainability Symposium: Water & Energy Policy in the 21st Century. The symposium is taking place in Salt Lake City, Utah, September 13 to 16, 2009 and the agenda features a veritable who’s who of scientists, researchers, utility and government folks sharing their work on water-energy issues.

Circle of Blue, a great website and resource dedicated to reporting the global water crisis, has created a module for Google Earth that allows users to visualize U.S. water consumption by state. The nifty educational module overlaps information from the U.S. Drought monitor so that you can compare a state's water consumption with the severity of drought in the region.

The EPA's WaterSense program provides a perfect example of how saving water saves energy (and money!). In 2008, consumers who installed WaterSense labeled toilets, faucets, and faucet accessories helped save more than 9.3 billion gallons of water, 1.25 billion kilowatt hours (kWh) of electricity and $55 billion on water and sewer utility bills. In addition, these savings avoided the emissions of nearly 1 million metric tons of carbon dioxide, which is equivalent to taking 180,000 cars off the road for a year!

Idaho has found great success reducing peak energy demand through an innovative program that provides incentives for farmers to turn off their pumps and stop irrigating in the late afternoon, when evapotranspiration rates are at their highest.

As one might imagine, the textile industry is very water-intensive. Water is required to clean the raw materials, then dye the fabrics and for a number of other production steps. In an effort to reduce their environmental impact, a few textile manufacturers have begun drastically reducing their water consumption through technologies that could be applied in your community.

The great folks out at the Pacific Institute just issued another timely report on water efficiency called Sustaining California Agriculture in an Uncertain Future. As the title suggests, the Pacific Institute outlines an array of strategies that can be implemented to help farmers get the most out of every drop of water and ensure that their farms remain productive in a future where water will become ever more scarce. Although the report uses California examples, its findings and general theme is relevant across the country.

A new report released yesterday in the UK by the Environment Agency and the Energy Saving Trust explores the energy and carbon embedded in residential water use. Titled Quantifying the Energy and Carbon Effects of Water Saving, the report concludes, among other things that 6% of the UK's carbon emissions are related to water and that Britons could save 30% of the carbon emissions from heating water through some simple retrofits.

The Alliance for Water Efficiency just released a new tool that is designed to help water utilities evaluate the water savings, costs and benefits of specific water conservation programs. Coined the Water Conservation Tracking Tool, this MS Excel based model can be promoted by river and watershed groups who want to encourage their local utility to invest in water conservation programs.

Robert Glennon, a renowned law professor at the University of Arizona and author of the new book Unquenchable: America's Water Crisis and What to do About It, was recently on The Daily Show with John Stewart. In addition to raising awareness of the looming national water crisis, Glennon introduced the audience to some key aspects of the water-energy nexus and the importance of integrating water and energy policies.

Due to the mounting body of research showing that large scale biofuel production will likely result in significant water demands and water quality issues, we've urged caution on policies that aggressively promote biofuels as a solution to the nation's energy problems. But there are more ways than one to skin a cat and a new project in Minneapolis, Minnesota is demonstrating how algae can be used at wastewater treatment plants to simultaneously clean sewage and make biofuels.

Over the last year or so, the promise of biofuels as a clean, renewable source of energy has been overshadowed by growing concerns over the freshwater impacts of large scale biofuel production. Despite these warnings, the National Renewable Fuel Standard program, established in 2007, mandates a four-fold increase in national biofuel production--from 9 billion gallons in 2008 to 36 billion gallons by 2022. While the verdict is still out on the pros and cons biofuels, a mounting body of research suggests that we might want to rethink our lofty biofuel targets.
