More Important than Home Energy Efficiency - Location Efficiency
At the 2010 RESNET conference, I heard David Goldstein speak on some of the issues he'd written about in his newly published book, Invisible Energy. Goldstein is the Energy Program Co-Director at the National Resources Defense Council (NRDC) and president of RESNET, and in one part of his talk, he threw out some numbers that floored me. Really! (It made a terrible racket, as I knocked over a few chairs and had trouble getting up again.)
He was discussing the mortgage crisis that has gripped the US since 2008 and wanted to put the cost of buying a house in perspective. At the time he wrote the book, the median price of an existing home in the US was around $175,000. If the buyer put down 20% and financed $140,000 over 30 years, here's about what they'd pay over the life of the mortgage:
- $350,000 in loan payments (PITI)*
- $300,000 commuting from suburbia
- $75,000 for utilities
I don't know about you, but that middle number really kinda surprised me. I knew that those folks who were spending hours a day driving were were paying with more than just time and frustration, but for the cost of commuting to be nearly as much as they're paying for the house shocked me.
Also, I'd never really thought about these numbers before, so if he'd have asked the audience that day, I think I'd've guessed that utilities would add up to more than the cost of commuting. Now that I've thought about it, though, it makes perfect sense. Cars are dang expensive, and the more you drive 'em, the more expensive they are.
This is an example of how cheap and plentiful oil over the past century and a half has reduced our location efficiency. Those who do long commutes from the suburbs to the city are impoverishing themselves, but they've done it for what seemed like a good reason: The further outside the big city you go, the less expensive the housing gets. There's even a name for this - the drive-till-you-qualify housing market.
In the book, Goldstein gives other measures of location efficiency, too. For example, when he looked at the most location-efficient places in the San Francisco Bay Area, he found that the mortgage default rate was less than 0.1%, whereas out in the Bay Area sprawl, it was 2.5%. Whoa! Save all that money on reduced driving expenses, and you get to keep your house. What a concept!
Not only have you been more likely to keep your location-efficient house, should you have one, you've also suffered much less in lost value over the past few years of declining house prices. Goldstein found this to be true in major metropolitan areas across the US in addition to San Francisco.
Getting back to the main point, it turns out that location efficiency can be much more important than home energy efficiency. With peak oil, expect the cost of poor location efficiency to cause more and more financial pain. The drive-till-you-qualify housing market, which reduces our energy security, is coming to an end.
This is another article in our series on energy security.
*Actually, Goldstein just gave the cost of the house ($175,000), not the sum of their loan payments.
