Apparently, a large traffic light installation such as this uses as much electricity in a month as a 3-bedroom house, and if Cape Town were to remove all its traffic lights from the grid, it would be equivalent to removing 1200 houses off mains power.
Aparentemente, una gran instalación de semáforos como esta consume tanta electricidad en un mes como una casa de 3 habitaciones y si Cape Town removiera todo el alumbrado público de la red de suministro, sería el equivalente a remover 1200 casas de la red principal.
