Good Thing #32: These New Fangled Lightbulbs
Incandescent lightbulbs are 90% inefficient. 90%! So 10% of the energy you're using goes to making light, while the remainder makes heat etc. It's technology that hasn't changed much in a century. I can't really think of any other technology that we'd put up with if it performed that badly and was that outdated. Fortunately, we don't have to. There are now fluorescent lightbulbs and LED lightbulbs. In the state of Maine, Efficiency Maine subsidizes fluorescent lightbulbs so they're crazy cheap. Even before this, I'd been buying them as soon as they came, and I've honestly never replaced one. They last forever. LED lighbulbs use even less power than the fluorescents and last even longer. If there's a down side it's that some of our lampshades don't fit anymore. So, they save me money, they save the hassle of blown bulbs, and they're better for the environment. What's not to love?
