1) Use compact fluorescent bulbs. Replace three frequently used light bulbs with compact fluorescent bulbs and save 300 pounds of carbon dioxide and about $60 a year. The Council on the Environment and Jewish Life is organizing a campaign called "How Many Jews Does It Take To Change A Light Bulb?" to encourage synagogues and other Jewish groups to replace conventional bulbs with compact fluorescent bulbs, which last four times longer but use 25 percent of the energy.

2) Buy a reusable water bottle. REI, the outdoor equipment store,
carries a 16-ounce Nalgene bottle, $7.95, in five colors, made from
polycarbonate plastic; it has a wide mouth and is easily washed.
Eastern Mountain Sports carries SIGG bottles from Switzerland,
including an 0.6-liter lightweight stainless steel model that is a
replica of a 1941 Swiss Army bottle, $20, in blue or red.

3) Pull the plug on electronics and chargers. Mobile phones,
BlackBerry devices, iPods, digital cameras and other electronics use
energy, even if they are turned off, if the charger is still going.

4) Take shorter showers. Water for bathing accounts for two-thirds of all water-heating costs.

5) Buy a hybrid car, when the time comes to replace your current vehicle.

6) Create idle-free zones. Schools, churches, synagogues, libraries,
shopping malls and anywhere that accommodates a large number of
vehicles are prime spots for signs requiring vehicle engines to be
turned off to help cut fuel emissions and improve air quality.

7) Buy local food products. You may pay a bit more in the grocery
store, but buying locally grown products helps the earth because less
fuel is required to transport your products to market. Additionally,
buying goods that require less packaging may help reduce your garbage.

8) Bring cloth bags to the market. Tote your own cloth bags to the
store instead of plastic and paper bags, reducing waste and requiring
no additional energy. Bring those bags for shopping of all sorts.

9) Put on a sweater instead of turning up the heat in your home.

10) Use recycled paper. Switch your home and business paper products
to 100 percent post-consumer recycled paper, saving countless trees and
five pounds of carbon dioxide per ream of paper. Look for chlorine
free. Even COSTCO is carrying it now, at least in Northern California…
