How serious is Norway about climate change? So much that its streetlights self-dim.
“The system, called Eagle Eye, is manufactured by a Norwegian company called Comlight. It’s one of several technologies Norway is deploying to cut its energy use.
This particular installation in Hole involves some 220 light posts fitted with radar that senses oncoming traffic and pedestrians.
When no object is detected nearby, however, the system dims the lights to 20 percent of total output, saving some 2,100 kilowatt-hours of electricity per week.”
According to the video, the energy cost saving pays for the added tech cost in less than five years – and that is with the cheap hydro power in Norway – meaning that other countries with higher cost per kWh, would have even bigger savings.
