Dams are usually an ecological nightmare, and the Colorado river is certainly suffering due to overuse by the western states that rely on its waters, not to mention Mexico which receives barely a trickle. But because of the heavy reliance on its waters, dams along the Colorado River are not going anywhere. So how might they be improved to be more energy efficient? Circle of Blue writes, "A digital system for the voltage regulators, electrical governors, and control panels will give dam managers more command over the system and allow them to position with greater accuracy the wicket gates that regulate water flow into the power plant's turbines."
The article is an interesting look at how technology can help improve energy use, and is a great, fast read.
