The Union of Concerned Scientists just released a new report on the effect of power plants on freshwater systems. “One plant had to curtail nighttime operations because the drought had reduced the amount of cool water available to bring down the temperature of water discharged from the plant,” the report says. It quotes Kent Saathoff, a vice president of the Electric Reliability Council of Texas, who said last month, “If we don’t get any rain between now and next summer, there could be several thousand megawatts of generators that won’t have sufficient cooling water to operate next summer” (New York Times Green Blog).

Sewage overflow is the No. 1 source of pollution for New York’s waterways, says Leif Percifield, a graduate student at the School of Art, Media, and Technology at the Parsons New School of Design… Percifield’s dream is to place simple sensors at each of New York City’s 490 “combined sewer overflow” points. The sensors will be primed to send out text-message notifications every time the city’s drainage maxes out (Grist). UC Berkeley has begun work in its quest to significantly taper its campuswide water use. The campus is aiming to cut its water usage by over 65 million gallons by 2020 (The Daily Californian).
