|Conserving Energy At Home||Energy|
Home energy conservation is low-hanging fruit. CSM:
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.
Mr. Janke had hit on what experts say is perhaps the easiest and most cost-effective place to reduce one's energy consumption: home.
Moving closer to public transportation or riding a bike instead of driving is not an option for many, but changing incandescent bulbs for fluorescent and buying more efficient appliances is not only possible, it quickly pays for itself with savings.
In the end, not-very-glamorous changes like these as well as obsessively sealing and insulating your home will save more than, in the words of one expert, "greenie weenie" additions like green roofs and solar panels. Twenty-two percent of all energy in the United States is used for residential purposes. (Transportation accounts for 28 percent.) And although residences consume only about two-fifths of this as electricity, because electrical generation is inherently inefficient, it accounts for 71 percent of household emissions. A home's electrical use may be responsible for more CO2 emissions than the two cars in the driveway. Ultimately, changes made at home may be the quickest, cheapest, and easiest way to reduce one's carbon footprint. [...]
"If you love your children, replace your lights," says Joseph Lstiburek, principal engineer of Building Science, a Boston-based consulting company that specializes in building technology. [Emphasis added]
He cut his electricity use by two-thirds. Savings like that are well worth the effort. What are we waiting for?
