A familiar engineering tenet says design is a trade-off — strength versus weight, weight versus speed, speed versus torque, and the like. Also to be considered, of course, is cost. Now add another trade-off: the environment. Green engineering throws an additional monkey wrench into the constant tug-of-war that is design
The general goal of green engineering is the optimization of energy, resources, or environmental impact. And, as with many other optimization tasks, computers and recent technology play a pivotal role.
Consider such applications as monitoring power-plant emissions, collecting rainforest data, and measuring electrical signals, which seem on the surface to have little in common, but that, in fact, are all forms of green engineering. Some of these processes were previously optimized for cost, so “reoptimizing” for environmental efficiency would seemingly be more expensive. It turns out this is not necessarily true.
