Food & Water

Food & Water

  • We're working with AT&T to find ways to reduce water and energy use in cooling towers.

  • Walmart, the world's largest retailer -- and largest grocer -- announces commitment to change the way it sources food.

  • We’re looking at three approaches to reduce water, energy and chemical use in the cooling systems of large buildings and data centers.

Why it matters

Last summer’s drought affected more than half the country. Companies are increasingly recognizing the potential risks of water shortages to their operations and supply chains as well as in the communities where they operate.

Why focus on cooling towers? To borrow Willie Sutton’s apocryphal catch phrase: “That’s where the water is.” Cooling towers use evaporative cooling to help lower the temperature in a building—and are one of the largest consumers of water in a given facility—including large office buildings and data centers. Thus, it makes sense to focus on a cooling tower rather than installing low flow faucets.
