Europeans reluctantly turn to air conditioning as heatwaves bite

As the summer breezes fade, sweltering Europeans are giving air conditioning a sceptical embrace.

During Europe's heatwave in July, Floriana Peroni’s vintage clothing store had to close for a week. 

A truck of rented generators blocked her door as they fed power to the central Roman neighbourhood hit by a blackout as temperatures surged. The main culprit: air conditioning.

The period - in which temperatures hit 40C - coincided with peak electricity use that came close to Italy’s all-time high, hitting a peak load of more than 59 gigawatts on 19 July. That neared a record set in July 2015.

Intensive electricity use knocked out the network not only near the central Campo de Fiori neighbourhood, where Peroni operates her shop, but elsewhere in the Italian capital.

Demand in that second July week surged 30 per cent, correlating to a heatwave that had persisted already for weeks, according to the capital’s electricity company ARETI.

Like many Romans, Peroni herself does not have AC either in her home or her shop. Rome once could count on a Mediterranean breeze to bring down nighttime temperatures, but that has become an intermittent relief at best.

“At most, we turn on fans,’’ Peroni said. “We think that is enough. We tolerate the heat, as it has always been tolerated.”

In Europe, though, that is starting to change.

How do Europeans combat the heat?

Despite holdouts like Peroni, rising global temperatures are dropping air conditioning from luxury to a necessity in many parts of Europe. The continent has long had a conflicted relationship with energy-sucking cooling systems deemed by many to be an American indulgence.

Europeans look with disdain at overcooled US buildings, kept to near meat-locker temperatures, where a blast of cold air can shoot across city sidewalks as people come and go, and extended indoor appointments necessitate a sweater even in the height of summer.

By contrast, event organisers in Europe may offer hand fans if events are expected to overheat. Shoppers can expect to sweat in under-cooled grocery stores, and movie theatres are not guaranteed to be climate-controlled. Evening diners have typically opted for outside tables to avoid stuffy restaurants, which rarely offer AC.

To deal with the heat, Italy and Spain typically shut down for several hours after lunch, for a riposo or siesta. Most people vacation in August, when many businesses shut down completely so families can enjoy a holiday at the seaside or in the mountains. 

Italians in particular are happy to abandon overheated art cities to foreign tourists, which reduces the urgency for a home AC investment.

Why isn't air conditioning popular in Europe?

Still, European AC penetration has picked up from 10 per cent in 2000 to 19 per cent last year, according to the International Energy Agency. That is still well shy of the United States, at around 90 per cent. 

Many in Europe resist due to cost, concern about environmental impact and even suspicions of adverse health impacts from cold air currents, including colds, a stiff neck, or worse.

Cooling systems remain rare in Nordic countries and even Germany, where temperatures can nudge above 30C for extended periods.

But even those temperate climates may cross the threshold of discomfort if temperatures increase beyond 1.5 to 2C, according to a new study by the University of Cambridge. 

In that scenario, people living in northern climes like Britain, Norway, Finland and Switzerland will face the greatest relative increase in uncomfortably hot days.

Nicole Miranda, one of the study's authors, said their estimate, which would mean surpassing the international goal of limiting future warming to 1.5C above pre-industrial times, are conservative.

“They don't take into account the urban island effects,” she said, when cities are unable to cool at night and surfaces become radiators. 

“From a scientific point of view, if we all run to the go-to solution, which is air conditioning, we are going to get into a different type of problem, because there is high energy consumption and high carbon emissions related to air conditioning.”

Cities should consider less intensive solutions, like shading buildings, and incorporating cooling bodies of water, she said. 

She also advocated a trend toward cooling individuals, instead of spaces, using personal devices like ice packs in jackets or high-tech textiles that dissipate body heat more efficiently.

There is growing demand for air conditioning in Europe

In Italy, sales of air conditioning units grew from 865,000 a year in 2012 to 1.92 million in 2022, according to the industry association Assoclima. These were mostly for business and not residential use, with growth reported in the first quarter of this year.  

Most are split heat air pump systems, that can heat spaces in the winter, which Assoclima says can reduce gas consumption as prices spike during the war in Ukraine. That dual-use attracts consumers.

France, with a slightly larger population, is showing more resistance, selling 1 million units a year. Air conditioning was rare in France until a 2003 heat wave killed thousands, mainly among the elderly. 

Still, most private homes and apartments there aren’t air-conditioned, and many restaurants and other businesses aren’t either. Businesses with AC will often advertise to attract customers on hot days.

AC aversion persists, both among French conservatives who see it as a frivolous American import and French people on the left who see it as environmentally irresponsible.

Cécile de Munck and Aude Lemonsu, meteorologists at France's national weather service, warned this summer that if the number of AC units doubles in Paris by 2030, the city temperature would rise by 2C because of heat released by the pump systems.

Despite the concerns over energy costs, air conditioning is rapidly conquering homes in Spain, a country that traditionally bent towards the use of fans and drawing heavy blinds, a very Spanish fixture. 

A study by Ca’ Foscari University projects that half of Spanish households will have AC by 2040, up from just 5 per cent in 1990.

Noise, cost and wasting energy put people off

With the cooler indoor air come disputes as neighbours complain about noise from external units. That means problems for Spain’s real estate managers. 

“Some people can’t open a window because they get a puff of fire,’' said Pablo Abascal, president of Spain’s council of real estate managers.

“With the increase of AC systems in homes, many buildings will soon have nowhere to place the devices."

Air conditioning and cooling were found to be key for older populations in extreme heat, reducing strain on cardiovascular functions in a heat wave of 37C, according to a study at the University of Ottawa in Canada. 

But even in countries like Cyprus, where heat waves of 40C have become the norm, the sustained use of AC isn’t an affordable option for many elderly people living on fixed incomes.

Many on the Mediterranean island nation restrict usage to the hottest times of day, sometimes confining themselves to a single room.

The prevailing fear is that refraining from using air conditioners could potentially lead to heat stroke.

“Undoubtedly, this scenario significantly impacts their mental well-being as well,” said Demos Antoniou, director of the Cyprus Third Age Observatory, a seniors-rights group.

“The prevailing fear is that refraining from using air conditioners could potentially lead to heat stroke."

At 83, Angeliki Vassiliou thinks both about her energy bill and future generations before she hits the “on” button.

“There’s no sense in wasting energy. Waste is unfair,” Vassiliou said. 

“Waste of any resource is wrong, because what would happen to our planet because of all this waste?”
