So to get to the appliances, you need to have power stations. From power stations, you need to have infrastructure, and that infrastructure takes you to the point of having electricity, and you get to the lightbulbs and the appliances that we all take for granted.
Para llegar a los aparatos, se necesitan centrales eléctricas, de las centrales parte la infraestructura, y esa infraestructura distribuye la electricidad, y alimenta las bombillas y los aparatos a los que estamos acostumbrados.
