Should I Unplug? part of SISL:2012 Sustainability in Math Workshop:Activities
A wide variety of electronic devices and small appliances are a regular part of students' lives: cell phones, laptops, iPods/MP3 players, hairdryers, irons, coffeemakers, printers, mini-refrigerators, microwaves, televisions, etc. Many of these products remain plugged in while not in use in students' dorms or apartments. In this project, students investigate the question "Should I unplug?" In particular, students measure plug loads of several products using a wattage meter, then compute the monetary costs associated with various unnecessary plug loads.
