Seville (Spain) has decided to replace gradually all the old halogen and incandescent traffic lights (that use 35 and 70W bulbs) for LEDs, which have a power output of only 6 to 15 W. This is claimed to save the city up to a 85 percent in the traffic light electricity bill, plus a bigger lifespan of the product. Savings are up to almost 4 million KWh which reduce CO2 emissions in 4,000 tons.
Other nice green project the city is the first light rail/tram system, which has completely transformed completely the city center and removed virtually all traffic.
el artículo viene a decir que la cidudad de Sevilla ha decidido mudar en los próximos años las bombillas de las farolas..qué más quiesa yo.. semáforos de la ciudad a la tecnología LED, esperemos que esta postura se extienda, bajo mi punto de vista en forma de ley.
