With my new, longer commute we’re going to finally replace our single car, a 1993 Nissan Sentra, with a newer car. The question is: what car makes the most sense, given both that we’re thrifty and that carbon emissions are prime drivers of global warming (no pun intended)?
We sized it up last night, now that we’ve finished doing our taxes (we’re early this year). The Prius can get 50ish miles per gallon, while a Honda Civic hybrid yields 38ish, but then the Prius costs about $4,000 more. And we’re convinced gas will be at least $4/gallon for most of the car’s lifespan.
Even so, the Prius would only save us about $300/year on gas. However, it would mean we were producing 25% less carbon emissions.
Because we’re financially solid with two good salaries, we care a lot more about our carbon footprint than saving $300. But if we saved $4,000 on the purchase price, what good things could we accomplish with that money? The jury is still out, and I’m wide open to input. What do you think is the best decision?
Finally, the elephant in the room I never see anyone addressing is: what is the carbon footprint of manufacturing all these ding-dang cars in the first place? That is to say, what is their embodied energy? My hunch is that it is enormous, and dwarfs the emissions we create by driving. Please give me a link to this information.
Possibly in the global picture, the best course is to buy no new cars at all until our current ones are literally repaired to death. I realize that course would shake up the economy — but a market transformation is what it will take, regardless, to deal effectively with global warming.
