energy efficiency

Mike Millikin, publisher of green-car blog, answers questions

Mike Millikin. What work do you do? I am the publisher/writer of Green Car Congress, a site covering technologies, issues, and policies for sustainable mobility. What does your organization do? What, in a perfect world, would constitute “mission accomplished”? My mission is to build a company that offers a portfolio of media products providing detailed […]

Umbra on spending wisely to help the environment

Dear Umbra, I read your column on how best to spend six hours of time a week on environmental issues, but how about the best way to spend limited financial resources on environmental issues? Obviously, giving a gift to Grist would help, but what can I do with my limited pocketbook to make the most […]

They met on the Prius showroom floor …

Environmentalists were there to lighten their ecological footprint. Neocons were there to lighten the fat Saudi pocketbook, full of petro dollars that fund terrorism. According to Robert Bryce, writing in Slate, the strange bedfellows have come together to advocate measures that would increase car fuel efficiency, lessen foreign oil dependence, and pump up renewables.

While Bryce pitches the "sleeping with the enemy" angle, the key point is there are multiple, compelling reasons to aggressively pursue (and for the government to subsidize) energy efficiency, renewables and alternatives to fossil fuels, and reduced dependence on overseas oil. Greens have often worked this issue with one hand tied behind their backs.

Umbra on Energy Star labels

Dear Umbra, When I see the Energy Star rating on an appliance, can I trust that some government or consumer group is monitoring the ratings, or is that just a commercial ploy? Who profits from the Energy Star thing? Not Starry-EyedBridgewater, N.J. Dearest Not Starry-Eyed, A green screen. Photo: EnergyStar.gov. Energy Star is a project […]

Umbra on whole-house fans and their righteousness

Dear Umbra, We just moved to the steamy climate of Washington, D.C., from the other Washington. Faced with our first experience using air-conditioning to cool our home, we’ve got some questions about efficiency. The house we’re renting has a central AC unit that we can control with a thermostat. It also has a roof ventilation […]

Umbra on opening windows versus running the AC

Dear Umbra, My friend and I have been having a debate that I hope you can help us settle. What is the rule of thumb when turning off the air and opening the windows? I live in Texas and in the spring we have one or two days in a row that are cool enough […]

Umbra on swamp coolers and their coolness

Dear Umbra, I recently visited Moab, Utah, and found that many people there use “swamp coolers” rather than conventional air-conditioning systems. Moab is in a near-desert environment and has frequent water-shortage problems. I’m wondering whether this swamp-cooler method of air-conditioning is really greener than the systems most of the rest of us use, and whether […]

Umbra on when to retire a fridge

Dear Umbra, I love to freeze fresh veggies at their peak of ripeness during the summer. Then, in the winter, I don’t have to buy commercially frozen veggies or long-distance transported ones. In order to do more of this, I’d like to move my 1985 refrigerator to the basement and use its freezer entirely for […]

Advice on heating tiny urban dwellings

OK, Umbra, I live in a building in Brooklyn where, in typical Brooklyn style, we do not control our own heat. That is, there is no thermostat in our apartment. Thus, our only options for regulating the temperature in the winter are turning off the radiators or opening the windows. Obviously the latter is an […]
