Why Not Turn Airports Into Giant Solar Farms?

THE NEXT TIME you’re staring out a plane window during takeoff or landing, give the airport a scan. You’ll see hangars and other support buildings and, of course, the terminal. But mostly, you’ll see lots of empty space. Airplanes, as many aeronautical engineers have noted, like open spaces—for obvious reasons, including not getting along with trees.

You know what also likes open spaces? Solar panels, which abhor the shade of not only trees but also tall buildings. So why aren’t we covering our airports—dedicated spaces that can’t be used for anything other than the business of air travel—with solar arrays? Well, it turns out that airports not only have a lot of empty space, they also have a lot of rules.

But let’s talk about their potential first. New research out of Australia shows how massively effective it would be to solarize 21 airports in that country. Researchers scanned satellite images of the airports for open roof space, where solar panels best avoid shadows, and found a total of 2.61 square kilometers, or 1 square mile, of usable area.

For comparison, they also scanned satellite imagery and found 17,000 residential solar panels in the town of Bendigo, just north of Melbourne in southern Australia. The researchers calculated that the airports could potentially produce 10 times the amount of solar energy as those 17,000 residential panels—enough to power 136,000 homes. Perth Airport alone would generate twice as much as Bendigo. (Perth is very sunny, and the airport has lots of big buildings.) They further calculated that solarizing all 21 airports would reduce greenhouse gas emissions by 152 kilotons a year, the equivalent of pulling 71,000 passenger cars off the road.

1. I guess they haven't flown into Indianapolis recently

That airport has had a solar farm on it's grounds for at least 10 years.

2. I worked at the Hulman Regional Airport in

Terre Haute, IN for several years. 84 through 90 or so... something like that. During the summer months, the airport leased the areas between runways and ramps to corn farmers. No joke... corn was literally growing between the runways and ramps. The crop dusters would spray the corn from time to time. Watching them was interesting.

I'm all for this solar field idea. If they can grow corn, they can farm solar energy. I never thought about it, but it kind of makes perfect sense. And, like the article points out, not just the areas not used on the ground, on top of every building on the site.

Eglin AFB in Ft Walton, FL has a couple of very large solar farms already. Along with the airport idea, I think that it could be expanded to include any, or all, publicly owned facilities. Like military bases, the rooftops of all federally owned buildings, etc. Maybe not publicly owned parks, but you get the idea.
