On the typical American roadway, it is not uncommon to see large advertising billboards. Even looking out my office window, I see two of them: one for an insurance company, and the other with a scantily clad woman (not exactly sure what that ad is for). These types of billboards have been around for a long time, but are slowly being replaced with new flashy electronic billboards. According to a new report, digital billboards consume large amounts of energy and create a variety of electronic waste.
