  • Umbra on convincing colleagues to turn the lights off

    Dear Umbra, I’m always hollering at my friends and colleagues to turn off the lights when they leave the room. Considering my business is green-related, it blows me away that my staff can’t seem to get a handle on flicking the switch. But it’s probably mostly a matter of them not really knowing why it’s […]

  • Umbra on fireplace inserts

    Dear Umbra, Our fireplace is terribly drafty when we’re not using it, and not very functional when we do. Despite the cheery blaze, most of the heat seems to go up the chimney. I tend to burn those “green” coffee logs since setting a real fire isn’t worth the trouble. My question is: should I […]

  • Umbra on pellet stoves

    Dear Umbra, I am a policy analyst with Californians Against Waste, a recycling advocacy group. Just wondering why pellet stoves were not considered in your wood stove analysis. I have one and feel that overall they rate well compared to other heating options. Thanks, Scott Smithline Sacramento, Calif. Dearest Scott, Omitting pellet stoves from my […]

  • Umbra on insulation

    Dear Umbra, I recently discovered that our attic is not insulated. While I live in the fairly warm climate of San Diego, we’ve been hit by a cold spell the last few weeks and I’ve cranked on the heater. I’d really like to insulate my home and was wondering what is the most planet-friendly method […]

  • Umbra on trusting scientists

    Hi Umbra, We’ve had some bizarre weather in New England, and more and more people are wondering if it’s due to global warming. On NBC News, they had a 30-year veteran of NOAA state flatly that it’s not global warming, it’s El Niño. As a greenie/leftie I got angry, thinking here goes the MSM denying […]

  • Umbra on burning yard waste

    Dear Umbra, Your recent column seemed to be discussing mostly the burning of trash. What about yard waste? Each year I pull out tons of non-native and invasive honeysuckle. There is far too much to take to a landfill, and it would take years to rot down if left in some kind of compost pile. […]

  • Umbra on tree planting

    Dear Umbra, My wife recently heard a program on NPR where an expert on global warming said that planting trees in the Northern Hemisphere plays a negligible role in fighting global warming, while playing a significant role in the Southern Hemisphere. Do you have any light to shed on this? Randy Cunningham, Confused Tree-Hugger Cleveland, […]

  • Umbra on which wood to burn

    Dear Umbra, I live in Maine, land of many loggers. My home is heated by an oil furnace, and I try to keep the temps down with thermostat timers to use as little oil as possible. I supplement my heat with a wood stove, as many Mainers do, and in my travels I have noticed […]

  • Umbra on that time of the month, again

    Dear Umbra, You mentioned in “Kid Commando” that the “disposable vs. reusable diaper fight is in a stalemate for the foreseeable future.” Is the same true for sanitary napkins? Clara Yuan Ithaca, N.Y. Dearest Clara, I haven’t heard tell of the debate, frankly. I certainly get several “which is better” diaper questions a month, but […]
