Just about all power plants use water in some way—primarily for cooling. In fact, generating electricity accounts for about 40 percent of all the fresh water that is drawn from reservoirs, rivers, and other surface sources in the United States. Kelly Sanders, an assistant professor of civil and environmental engineering at the University of Southern California, has developed new methods of analyzing the complex relationship of water and energy—and is showing how both resources can be managed more wisely.
Although power plants typically return water to the source after it runs through cooling systems, those withdrawals and returns can be disruptive to the environment. Many newer coal and natural-gas plants reuse water in their cooling systems so they do not need to withdraw as much of it from reservoirs and rivers, but in the process they lose more water to evaporation. And that means, as Sanders has highlighted, that many newer plants end up consuming more water overall. She also looks carefully at the water individual nuclear power plants use to keep from overheating and causing a meltdown. If the water source gets too warm and must cool down before it can be used, forcing the power station to scale back production, are the costs of the plant being miscalculated?
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
