Compact fluorescents: The yearly dollar savings from buying fewer bulbs and less electricity is $4 to $6 per bulb. Over its life, each bulb saves the combustion of 500 pounds of coal at a power plant. Each bulb cost about $20. Honda Civic: Our favorite ... is the Honda Civic CRX. Yes, the Geo Metro XFI gets better mileage (58 m.p.g. on the highway versus 49 for the Civic), but our testers tell us that it does so at the expense of power (the engine is 33 percent smaller) and general handling....

Caulk and weather stripping: Most of our houses are so full of holes they're virtual sieves in terms of heating; just as fast as we pump heat into them, it leaks right out again.

Since I hate pesticides as much as I do mosquitoes, putting up a bat house to encourage these mammals to move into my neighborhood was irresistible.
