Umbra on tankless water heaters
Dear Umbra, While you were warning folks to plan ahead for a potential water-tank failure, I thought you should mention the natural gas heat-on-demand systems that they should use to replace their tanks. Last spring, when our 50-gallon tank decided to give our basement floor a thorough cleaning, we had to scramble to find an […]

Umbra on wood stoves
Dear Umbra, When you suggested that someone may want wood heat because it “makes you feel like a country stud,” you made an erroneous assumption — that your audience is entirely urban. Here in Skamokawa, Wash., many a mile from the nearest natural gas line, the choices are essentially wood or electricity. In September, my […]

Whitman highlights Republican rift on environment
Whitman has her say. On Monday, former U.S. EPA Administrator Christie Todd Whitman published an uncharacteristically opinionated commentary in the New York Times lamenting the Bush administration’s disregard for moderate Republican viewpoints. Though gently worded, the op-ed stands as the closest thing Whitman has made to a confession that she abandoned her post over an […]

Umbra on water heaters
Dear Umbra, I have a question that’s been nagging at me for some time. Since I have a water heater inside my house, any waste heat from the water heater contributes to heating the house. Does it still make sense in terms of energy savings to put an insulating blanket on the water heater? KurtLittleton, […]

Umbra on turning down the thermostat
Dear Umbra, My housemates and I are engaged in an ongoing argument about the heat (gas) in our somewhat old house. I argue that for the minimum eight hours that we are out of the house during the day, we should turn our heat down to at least 62 degrees. They argue that we should […]

Umbra on home heating
Dear Umbra, Can you shed some light (or some warmth) on the most environmentally sound ways to heat one’s home this winter? Natural gas over coal and oil for its lower carbon (and particulate) content? What about fireplaces: good or bad? Would burning gas logs be a good alternative to burning real wood? Thanks for […]

Umbra on microwaves
Dear Umbra, We recently bought a new (to us) house and acquired a microwave oven. Having gotten this far in life without one, we figured we wouldn’t use it all that much. Ha. We use it all the time. It’s just so much faster than heating things on the stove. I do wonder, though, which […]

Umbra on supermarket coolers
Dear Umbra, Every time I go to the grocery store and see meats, dairy products, and other products displayed in open-air refrigerators, I get a little miffed and wonder if this isn’t a huge waste of energy and a tremendous cost to the supermarket as well. Do supermarkets make more money having their products in […]

Umbra on car heaters
Dear Umbra, My friend and I have a bet going that I hope you can settle. She thinks that running the heat in a car in the winter is “free” — that is, it doesn’t use additional gas. As a conservationist, this pleases her greatly. However, I think that turning on the heat does use […]
