Interview with makers of Who Killed the Electric Car?

Hoping to share a little bit of the spotlight with that other eco-themed documentary -- alongside which it debuted at the Sundance film festival -- Who Killed the Electric Car? will drive (without emissions!) into theaters next month (or tomorrow, if you're in NYC or L.A.).

On June 9, I sat down for a wide-ranging discussion with Chris Paine, the director, Chelsea Sexton, an activist prominently featured in the film, and Wally Rippel, an engineer who played a role in developing the power system for the late, lamented GM EV-1.

For still more electric-car interview fun, go here.

DR: So I started watching this movie, about this one peculiar car, and then about halfway through all the sudden I'm watching a movie about fuel economy and global warming and energy security. Did you use the former as a hook for the latter, or did the former just carry you into the latter?

CP: That's an excellent question. When I started filming I wasn't thinking [about the bigger issues], but by the time we were editing it's like, this is such a great microcosm.

It's more than a car story, you know. I mean, much more than a car story.

DR: How did you hear about the EV? I'm sure I'm not the only one who had no idea it even existed before the movie came out.

Umbra on replacing light bulbs

Dear Umbra, I am reluctant to switch to compact fluorescent light bulbs because that means tossing out not only used-but-still-working incandescent bulbs, but also the brand-new bulbs I have waiting in the closet. Is it really a positive effect overall when we’re reducing our carbon emissions but adding to landfills? Julie Pittsburgh, Pa. Dearest Julie, […]

Umbra on personal fans

Dear Umbra, So the weather is turning hot again. I got my electric fans out of the closet. On the back of these, there are no indications of what amount of electricity they use. Could you illuminate which ones are most efficient? Howard Nelson Portland, Ore. Dearest Howard, Not really. Efficiency is very important for […]

Umbra on global warming and you

Dear Umbra, I love the scientific ins and outs, really I do, but what oh what can we do about global warming? And I mean us ordinary folks with a house and mortgage and some percentage point of kids and a few compact fluorescents and maybe even a hybrid in the driveway. We’re right there […]

Get smart

This is a bit far afield, perhaps, but the British press is reporting that new drivers in the UK will soon have to take an "eco-driving" test in order to get their license. The UK initiative is modelled after a Dutch program that claims that smarter driving habits -- slower acceleration, less braking, lower top speeds -- can shave gas consumption by a third or more.

Last year, after a brief (and undeserved) flap over they Toyota Prius's worse-than-advertised mileage, ardent hybrid enthusiasts began circulating advice about how to maximize the vehicles' efficiency. So it's good to see some effort to do the same thing for the 99+ percent of cars on the road that aren't hybrids.

Are you America’s most energy-inefficient person?

Just got word that Lowe's, Whirlpool, and the U.S. EPA Energy Star program will search this summer for the country's 10 most energy-inefficient families. The lucky winners will receive a home energy makeover "to lower their monthly bills and help save the environment" and a return visit a year later to see how it's all going. During the search, Lowe's stores will host hands-on energy-conservation clinics. It's all in honor of the 10th anniversary of people ignoring Energy Star.

Umbra on fireplaces

Dear Umbra, We pile on socks and sweaters, but there are just times you need more warmth. Should we use the fireplace or our central (gas-powered) heater? Also, can you let us know which is better, natural firewood or those chemically infused logs that claim lower particulate matter is released? Kas SutDavis, Calif. Dearest Kas, […]

Umbra on replacing appliances

Dear Umbra, I’ve done the research, and I’m ready to buy my first front-loading washing machine. And then a pesky friend starts asking the tough questions. “Does your existing machine work?” Yes. “Are you going to sell it to someone else who will keep using it?” Yes. “So, two machines where there used to be […]

Umbra on LED holiday lights

Dear Umbra, Suppose I replace all my many old, tangled, not-so-efficient holiday lights with the newer LED lights. These are supposed to be better for the environment. What is the best way to dispose of my old lights? R-MOttawa, Canada Dearest R-M, The LED lights are indeed better for the environment, and, since I’m frankly […]
