About two weeks ago Taiwan decided to replace the halogen traffic lights with LED units for the sake of the planet by reducing power consumption. It looks like the city of Seville (Spain) announced the same and that is because LEDs have a power output of 6 to 15W instead of those incandescent bulbs going for 35 to 70W.

These actions will save somewhere near 85% of the traffic light electricity (~ 4 million KWh) that will reduce CO2 emissions in 4,000 tons. Another reason to do it is an increased life span, because LEDs are much better. Another green project in the city of Seville is a light tram/train system that will cut down the costs of transportation.
