Over the past decade, the average price of a 16-ounce bag of potato chips has jumped from under $4.50 to around $6.50—outpacing inflation for most grocery items. While global supply chains and fuel costs play a role, the root of the issue may lie in the fields of Pennsylvania, where climate change is making it harder to grow potatoes for America’s favorite snack.
As the Super Bowl season approaches, millions of Americans will reach for a bag of chips—but few may realize how weather patterns, transport costs, and farming conditions are shaping what they pay at the register.
According to USDA Economic Research Service data, the price of potato chips has risen nearly 44% over the past 10 years, while general food inflation over the same period has averaged closer to 30%. And unlike many pandemic-era food spikes, chip prices haven’t stabilized. So what’s behind the crunch?
Climate Change Hits the Chip Belt
Pennsylvania, home to more potato chip makers than any other U.S. state, plays a central role in domestic chip supply. Companies like Snyder of Berlin depend on fresh, locally grown potatoes to avoid long-distance transportation—keeping costs and emissions down.
But the climate is changing, and so is potato farming.
Agronomist Bob Leiby from the Pennsylvania Co-Operative Potato Growers says that rising nighttime and soil temperatures are harming tuber development:
- In Erie County, the number of summer nights too hot for optimal potato growth has increased from 35 nights/year in the 1980s to 50 nights/year today.
- When soil temperatures exceed 85°F, tubers stop developing, or worse, rot in the ground.
Potatoes prefer:
- Cool nights (~50°F)
- Daytime highs below 85°F
- Moist, but well-drained soils
Conditions that are becoming harder to achieve with each passing season, especially in the Northeastern U.S.
Transport, Chips, and the Cost of Distance
When local crops fail due to heat or poor soil conditions, factories source potatoes from farther away—often from Idaho or Washington, the largest potato-producing states. While these western regions benefit from:
- Longer growing seasons
- Mechanized irrigation
- Larger plots of land
They also require long-distance shipping—which can increase input costs by up to 25%, especially when fuel prices are volatile.
“Potatoes out West may be cheaper to grow, but transporting them thousands of miles isn’t always cost-effective or sustainable,” says Walter De Jong, a potato genetics expert at Cornell University.
De Jong emphasizes the strategic value of maintaining local production, especially for:
- Supply chain resilience
- Price stability during disasters or droughts
- Seasonal surges in demand (like during the football playoffs)
In 2011, Cornell released a potato variety bred to help Northeast farmers store crops longer, ensuring chipmakers can rely on local supplies deep into the season.
Chips, Sustainability, and the Future of Farming
The situation in Pennsylvania is just one example of how climate variability is pressuring traditional farming regions. It’s prompting researchers, breeders, and farmers to:
- Develop climate-resilient potato varieties
- Improve soil and water management
- Diversify local production to reduce dependence on distant sources
At Kevin Troyer’s farm in Waterford, PA, cooler nights in 2024 helped ensure a healthy harvest—but Troyer knows such seasons are increasingly rare. “Potatoes love cool nights,” he says. “But we can’t rely on luck forever.”
The rising cost of potato chips is a reminder that the supply chain starts in the soil. As climate pressures mount, supporting local potato production in regions like the Northeast is essential—not just for price control, but for sustainability, resilience, and food security. Investing in climate-smart farming, regional breeding programs, and local infrastructure could be the key to keeping America’s favorite snack affordable—and available—year-round.
