Ann Arbor street lights to be replaced with LEDs - Engadget: "
"
Flying over the country deffinitely makes you realize how much light is used to light the outdoors(and thus money and future money to reduce carbon emissions and save the enviroment)
Despite my fervent wish for motion sensors the trend seems to be in switching to LEDs (Though motion sensors would be cheaper and still solve the safety issue -- though I question the $ effectiveness of streetlights everywhere vs. $ spent on police or other safety)
