Electricity Savings

Surprise: Not-so-glamorous conservation works best

When high school science teacher Ray Janke bought a home in Chicopee, Mass., he decided to see how much he could save on his electric bill.

He exchanged incandescent bulbs for compact fluorescents, put switches and surge protectors on his electronic equipment to reduce the “phantom load” – the trickle consumption even when electronic equipment is off – and bought energy-efficient appliances.

Two things happened: He saw a two-thirds reduction in his electric bill, and he found himself under audit by Mass Electric. The company thought he’d tampered with his meter. “They couldn’t believe I was using so little,” he says.

Cutting back on electricity used for lighting (9 percent of residential usage nationwide) presents the quickest savings-to-effort ratio. The EPA estimates that changing only 25 percent of your home’s bulbs can cut a lighting bill in half. Incandescent bulbs waste 90 percent of their energy as heat, and compact fluorescents, which can be up to five times more efficient, last years longer as well.

I am far from doing everything I could, but at least I have installed compact fluorescent light bulbs as old ones burned out. Actually I don’t think I have changed a light bulb in several years (another benefit of these energy efficient lights is they last a long time).

    “On average 8x as much air is exchanged when a swing door is opened as opposed to a revolving door. That’s 8x as much new air that needs to be heated or cooled and that’s why using the revolving door is a great way to reduce energy requirements on campus…”

    I’m also using energy efficient lights. Aside from CFL, I’m also using halogen and LED light bulbs. I agree with you that energy efficient lights last for a long time. My lights are with me for several years already yet they didn’t burned out.

    LED lamps are the right choice for those who are looking for energy savings, and hopes in a more “green” world, led lamps are not longer cold and technology objects , but they are beginning to be beautiful objects suitable to decorate your homes. We are working on this project for a couple of years, for example, we are very satisfied with the results of the desk lamp “Asymmetric” completely built in glazed ceramic, it use as light source 8W LED. (like 70w traditional bulbs).
