We flip a switch, and like magic, a room fills with light. It’s something we hardly think about—until the electricity bill arrives, that is. But have you ever wondered just how much electricity a light bulb uses every time you brighten up a room? And how much it costs to run?
Sure, it’s just a tiny bulb, but with lights glowing in every corner of the house, those watts can start to add up faster than you’d expect, as your smart meter (and a nagging partner or parent) may verify. And with darker evenings and mornings on their way, our lights will soon be on a lot more.
