One thing I’ve been working on at the new house is replacing all of the old incandescent light bulbs with LEDs. It feels like a herculean task because there are so many lights here… the party room alone has 42 floods! But I love the satisfaction of removing these gigantic heavy bulbs and replacing them with smaller, lighter, far more energy-efficient ones:
The old one on the left draws 90 watts of power. The new LED one on the right gives off just as much light for 8.5 watts. That’s an order of magnitude less power. Multiply by 42, and our parties won’t break the bank on the electric bill any more!
Of course, there’s an up-front cost as I buy a couple hundred LED bulbs, but theoretically they should last the entire time we live here (and then some), so I won’t have to change another bulb, ever. Definitely worth it.
