What would Houston look like without air conditioning? Just step outside.
Houston and air conditioning have one of the great co-dependent relationships in American history.
We wouldn't, couldn't exist without it, at least at this size. And yet the technology that makes our existence here possible has also made us a little oblivious, no? Sealed inside our climate-controlled bubbles and insulated not just from the heat but from the reality of what this city actually feels like when the elements really bear down on you.
But in a city built around the assumption that everyone gets to escape into a home, an office, a car, there are plenty of people who don't. The lesson is this: Houston's heat is avoidable, only if you can afford to avoid it. (A thank you to EJ Nolan, who submitted this week's question and gave me an excuse to go on this tangent.)
The city that A/C built
Houston's population in 1900 was a modest 44,000 people. By 1960, as air conditioning became widespread, it was nearly a million. Today, in not just Houston but the whole metro area, the region is home to nearly 8 million people.
The postwar boom that turned the Houston area from a fledgling port on the muddy banks of a bayou into a legitimate American megalopolis was powered, quite literally, by the ability to make the environment bearable.
Just look at how we've built things over the years. Consider that the original Gulfgate Shopping Center, which opened in 1956, is widely remembered as one of the first air-conditioned malls in the country. And what about those massive glass towers downtown, where our oil analysts and finance bros run the numbers that apparently power the city's economy? And all the tunnels that run underneath them? Those poor office workers would cook in there without A/C!
Even our sprawl, the region's defining characteristic, is an A/C story. The suburbs ("Oh, but the homes are so much cheaper out here, and it's so much quieter, and have you seen the kitchen?") don't exist without the guarantee that the house you're pulling up to at the end of your commute will be cool enough to make you forget that you just spent 45 minutes roasting inside of a car to get there.
Our city's existence is a giant gamble on the electricity never going out, and if the past decade has taught us anything, it's that Houston's odds are terrible.
Still out there
Somewhere out there, while you're reading this in your air-conditioned living room or your air-conditioned office or your air-conditioned car, there are other Houstonians standing in the sun, and they have been since the sun came up.
Consider the day laborers and construction workers who show up before dawn to build our roads, our subdivisions, our glass towers, pouring concrete and framing homes in the heat so that our metropolis can continue to flourish and function.
There are the women working the medians of our busiest intersections, selling fruit and flowers out of buckets with their kids beside them, baking in the exhaust fumes. Then come the parents without cars (and there are so many of them, so many more than most of us realize) who push strollers on cracked sidewalks in a city not built for walking, past stretches of concrete and asphalt that trap the heat, in neighborhoods where tree cover is a rarity and the bus stop has no cover and the nearest grocery store is a 30-minute walk in weather that can, if you're not careful, kill you.
And then the people who have no home to return to, who, just to survive, find shelter in the shade of an overpass, a bush.
This is the city that air conditioning built. For some of us, anyway.
