Digital Billboards

“The growing number of digital billboards on U.S. roads and highways consume large amounts of energy and are creating a wide variety of electronic waste, according to a new report (pdf). The new study says the typical digital billboard consumes about 30 times as much energy as the average American household.”

Energy use led billboards“The digital billboards use more efficient LED (Light Emitting Diode) lighting than traditional signs, but deploy so many of the LED bulbs on each billboard that energy use is high; traditional billboards use just one or two large bulbs to illuminate signs. In addition, digital billboards are illuminated day and night, and require cooling systems that use more energy.”

It is responsible for 3 to 12 percent of residential electricity use worldwide (source, pdf). Freelance journalist Robert Buzink has a low-tech solution for this – all you need is a pair of scissors and a screwdriver. The text is in Dutch but the pictures speak for themselves.
