Three Cheers for Refrigeration—and Four, Once Everyone Has It

Refrigerators have revolutionized health and wellbeing for those with access to them, but their affordability is under fire.

Summary: Refrigeration has revolutionized public health and improved the quality of life worldwide, but its future is under threat. The remarkable benefits it brings, such as reducing foodborne illnesses and improving the quality of food, are being undermined by misguided climate change policies that increase costs. This article explains why it is crucial to prioritize the accessibility and affordability of refrigeration and reliable electricity, as they are such powerful keys to human progress.


It is difficult to overstate the benefits of refrigeration. Even more than its technological sibling air conditioning, refrigeration has dramatically improved public health and the quality of life wherever it has become widespread. And unlike air conditioning, the utility of which is questioned in some intellectual circles, refrigeration has few if any critics. Nonetheless, in an age when climate change has become the near obsession of most international policymakers—and given that refrigeration does require a considerable amount of (often) fossil-fuel fired electricity—it is worth highlighting the importance of avoiding measures that threaten its continued spread throughout the world.

The Rise of Refrigeration and Fall of Foodborne Illness

In 2013–2014, salmonella-contaminated chicken from Foster Farms in California caused a known 634 illnesses across 29 states. This major outbreak and recall received substantial press coverage at the time, as have similar ones that have happened. But before refrigeration, such incidents would not have been treated as news; they were an everyday reality.

Along with air conditioning, the United States was the first nation to have a refrigerator in most residences, as well as an extensive cold chain among food producers and wholesalers and retailers upstream of the consumer. Therefore, America provides the longest test case of the public health benefits from having a food supply that can be kept cold as needed. Those benefits are impressive.

It is over the last century that American households went from zero to nearly 100 percent in refrigerator use. Indeed, market penetration was already above 80 percent by the 1940s. Thanks to a fridge in every kitchen, and along with other major advances like pasteurization, food-related illness and mortality have seen a precipitous decline.

Even health outcomes not obviously connected to refrigeration have benefited from it. For example, there is considerable evidence that cancers of the stomach became considerably less common in the United States thanks to refrigerators.

Beyond reducing foodborne illness, refrigeration has also improved the quality of the food supply. This is particularly true for protein sources like dairy, meat, and fish that are quickly perishable without it. It has also enabled wider and year-round availability of fresh fruits and vegetables. These fresh (and also fresh frozen, as sizeable freezer sections have become a standard feature in refrigerators) foods have largely replaced heavily salted or smoked or pickled foods, and thus improved diets.

Lower income households have benefited the most from refrigeration. Not only has the cost of a high-quality diet come down, but the once-considerable expense of food spoilage has been reduced. This is particularly important for those who live in hotter regions.

Given all the health benefits of a safer and better food supply attributable to refrigeration, there is little doubt it has contributed to the considerably longer life expectancies in the United States over the past century. Granted, improved health care has been the main driver of these improvements, including vaccines against many once-common diseases. But even with that, refrigeration has played a vital role in the manufacture, transport, and storage of those vaccines as well as in many other medical applications.

Progress and Challenges toward Global Availability of Refrigeration

Refrigerators started as a luxury good a century ago, but prices have substantially declined since (although it should be noted that the recently growing regulatory burden on appliances in the United States and Europe may undercut this trend). Today, very few kitchens in the developed world are without a refrigerator, and market penetration in the developing world has been robust, particularly over the last three decades.

At this point, equipment cost is a barrier for only the world’s very poorest households. However, United Nations efforts favoring “climate-friendly” refrigerators represent a worrisome trend threatening affordability. For example, many existing refrigerators use refrigerants called hydrofluorocarbons (HFCs) that are considered to have a high per-molecule global warming potential, though their overall contribution to anthropogenic warming is only 3 percent. These refrigerants are now subject to restrictions pursuant to the Kigali Amendment, a United Nations treaty.

Although the Kigali Amendment is more lenient toward developing nations than developed ones, it will nonetheless harm the developing world’s refrigerator buyers in two ways. First, the treaty and implementing provisions will serve to disrupt with the supply of second-hand refrigerators from first-world nations, which are often the lowest cost option in developing nations. In fact, the trade in such refrigerators is now perceived by many in the international community as an environmental threat that needs to be eradicated. Second, the Kigali Amendment will eventually impose restrictions on the types of new systems allowed to be produced in developing nations.

These measures are fairly new and are just beginning to be implemented, so the impact on equipment costs is not yet known. But they will likely raise, at least to some extent, the purchase price of a refrigerator. It does not take much of an increase to have a deleterious impact on market penetration among the world’s poorest households.

Access to Reliable Electricity

While refrigerator affordability is an ongoing concern, the greater obstacle is access to reliable electricity.

The slow march to a completely electrified world is 90 percent complete. We have finally reached the point where most of the developing world has joined the developed world in being electrified, but about 750 million people still don’t have it. Worse, by adding in those lacking access to reliable electricity, the number jumps to 3.5 billion, according to one estimate. In Africa, less than half the population enjoys access to reliable electricity.

An unreliable electricity supply can significantly undercut the advantages of refrigeration, as anyone who has had to clean out the fridge after an extended blackout can attest. More progress on both the availability and reliability of electricity is still needed if the benefits of refrigeration are to become universal.

Once again, the climate change agenda is becoming a growing impediment. Progress on electrification is jeopardized by the United Nations’ Paris Agreement and other measures that target affordable and reliable—but carbon-emitting—coal and natural gas in favor of intermittent and unreliable wind and solar. Doing so threatens to both slow progress in expanding electrification for those who don’t yet have it and to improve reliability for those who do.

Even in the first world where refrigeration has long been nearly universal, there are risks from mandates and subsidies for an increasingly renewables-heavy electricity mix chosen for climate considerations at the expense of reliability. If unchecked, this trend could lead to more frequent blackouts and, thus, backsliding on the refrigeration benefits people take for granted. This is especially so for the summer months when refrigeration is most vital.

Conclusion

Today, a large and growing number of the world’s households, both rich and poor, are able to buy a refrigerator, plug it in, and enjoy the benefits of its uninterrupted operation. This has been an indisputably significant boon to the safety and quality of the food supply and thus to public health. However, ill-advised climate change policy measures are emerging as a real threat to refrigeration’s continued spread. Prioritization of a climate agenda that raises the cost of a refrigerator is likely to do considerably more harm than good and deter the spread of affordable and reliable electricity throughout the world. Refrigeration has been a growing success story for humanity over the past century, but continued progress is now at risk.

Billionaire-Backed Nonprofit Begins Relocating Key Rhino Herd

“A billionaire-backed nonprofit has begun relocating captive-bred southern white rhinos to protected wild areas after the purchase of the world’s biggest privately-owned herd of the animals last year.

African Parks, whose backers include the charitable foundations of Howard Buffett and the Walton Family, said it donated 40 of the 2,000 rhinos it acquired along with the distressed operation in central South Africa to the community-owned Munywana Conservancy in the southeast of the country. The translocation is the first step in a plan to relocate 15% of the global population of the pachyderms.”

The Human Meaning of Economic Growth

Misunderstandings of the relationship between wealth and flourishing have obscured the anti-​human implications of slowing growth rates.

Summary: Economic growth has been a driving force behind the dramatic improvements in human wellbeing over the past few centuries. This growth has resulted from the Enlightenment, the Industrial Revolution and capitalism. Criticisms of growth stem in large part from misunderstandings of the relationship between economics and human values.


Why is the world as prosperous a place as it is? And why isn’t it much more prosperous? These questions are broad enough to admit countless answers, but as good an answer as any is the economic growth rate.

You might have heard that economic growth is overrated, that it’s a fine idea, but unsustainable, or even that it’s entirely counterproductive because it puts profits above people and the economy above the planet. These narratives have been widespread in recent years. They’re also based on a fundamental misconception of the nature of wealth and what a growing economy means for humanity.

Properly conceived, wealth is the actualization of human values in the real world. Economic growth is the upward trajectory of human achievement. The forms of prosperity that most of humanity strives for, such as health, knowledge, pleasure, safety, professional and personal freedom, and so many others, were vastly scarcer throughout most of human history—and would be orders of magnitude more abundant today if economic policies had been slightly different. That is the power of economic growth, and it is within our power to influence the world of future generations for better or worse.

The History of Economic Growth

Virtually everywhere and always throughout human history, economic growth was nonexistent. While pockets of momentary economic progress took place in certain instances, the overall trend was one of perpetual stagnation. But just a few hundred years ago, with the advent of the Enlightenment, the Industrial Revolution, and capitalism, that all began to change.

When the conceptual tools of science became widely applied to create the technological advancements of the Industrial Revolution, they brought an unprecedented optimism about the capacity for investment in new discoveries and inventions to reliably uncover useful knowledge of the natural world. This change inspired the broad transformation of mere wealth (resources hidden away in vaults and treasure chests) into capital (resources invested in new inventions and discoveries).

By the time Friedrich Engels and Karl Marx wrote their Communist Manifesto in 1848, the optimism of investment had already transformed Western Europe. As Engels and Marx saw it, “The bourgeoisie [capitalist class], during its rule of scarce one hundred years, has created more massive and more colossal productive forces than have all preceding generations together. Subjection of Nature’s forces to man, machinery, application of chemistry to industry and agriculture, steam-​navigation, railways, electric telegraphs, clearing of whole continents for cultivation, canalisation of rivers, whole populations conjured out of the ground — what earlier century had even a presentiment that such productive forces slumbered in the lap of social labour?”

Marx and Engels misunderstand the complex reasons for increased productivity (attributing it to untapped “social labour”) but the quotation is significant because, despite their sympathy for state centralization of the economy, they could not ignore the success of capitalism.

While no year before 1700 saw a gross world product of more than $643 billion (in international inflation-​adjusted 2011 dollars), by 1820 global GDP reached 1 trillion. By 1940 the number had passed 7 trillion, and by 2015 it had passed 108 trillion.

Contrary to the popular misconception that capitalism has made the rich richer and the poor poorer, this new wealth contributed to growing the economies of every world region while outpacing population growth. While the world’s extreme poor have become wealthier so too have all other economic classes.

What’s So Great about Growth?

A growing economy isn’t about stacks of paper money getting taller, or digits being added to the spreadsheets of bank ledgers. These things may be indicators of growth, but the growth itself is composed of goods and services becoming more abundant. Farms and factories producing more and better consumption goods; engineers creating better machines and materials; clean water reaching more communities; sick people receiving better healthcare; scientists running more experiments, poets writing more poems, education becoming more broadly accessible; and for whatever other forms of value people choose to exchange their savings and labor.

Gross domestic product or GDP (called gross world product or world GDP when applied at the global level) is an imperfect but useful and widely employed measure of economic growth, and its reflection in the real world takes such forms as rising life expectancy, nutrition, literacy, safety from natural disaster, and virtually every other measure of human flourishing. This is because, at the most fundamental level, “economic growth” means the transformation and rearrangement of the physical environment into more useful forms that people value more.

Before the year 1820, human life expectancy had always been approximately 30-35 years. But with the great decline in poverty and rise of capital investment in technology and medicine, global life expectancy has roughly doubled in every geographic region in the last century. Similar trends have occurred in global nourishmentinfant survivalliteracy, access to clean water, and countless other crucial indicators of wellbeing. While these trends are bound to take the occasional momentary downturn because of life’s uncertainties and hardships, the unidirectional accumulation of technological and scientific knowledge since the Age of Enlightenment gives the forward march of progress an asymmetric advantage. For example, the COVID-19 pandemic and lockdowns resulted in a brief and tragic decline in life expectancy, but the number has since risen to an all-​time high of 73.36 years as of 2023.

What is the direct causal connection between economic growth and these improvements to human wellbeing? Consider the example of deaths by natural disaster, which have fallen in the last century from about 26.5 per 100,000 people to 0.51 per 100,000 people. More wealth means buildings can be constructed from stronger materials and better climate controls. And when those protections aren’t enough, a wealthier community can afford better infrastructure such as roads and vehicles to efficiently get sick or injured people to the hospital. When those injured end up in the hospital, a wealthier society’s medical facilities will be equipped with more advanced equipment, cleaner sanitation, and better-​trained doctors that will provide higher quality medical attention. These are just a few examples of how wealth allows humans to transform their world into a more hospitable place to live and face the inevitable challenges of life.

The benefits of economic growth go far beyond the maximization of health and safety for their own sake. If what you value in life is the contemplation of great art, the exaltation of your favorite deity, or time spent with your loved ones, wealth is what awards you the freedom to sustainably pursue those values rather tilling the fields for 16 hours per day and dying in your 30s. Wealth is what provides you access to an ever-​improving share of the world’s culture by increasing the abundance and accessibility of printed, recorded, and digital materials. Wealth is what provides you with the leisure time and transportation technology to travel the world and experience distant wonders, remote holy sites, and people whose personal or professional significance to you would otherwise dwell beyond your reach.

As the Harvard University cognitive scientist Steven Pinker demonstrates in his popular book Enlightenment Now, “Though it’s easy to sneer at national income as a shallow and materialistic measure, it correlates with every indicator of human flourishing, as we will repeatedly see in the chapters to come.”

The Long-​Term Future of Growth

Human psychology is ill-​equipped to comprehend large numbers, especially as they relate to the profound numerical implications of exponentiation. If it sounds insignificant when politicians and journalists refer to a 1 percent or 2 percent increase or decrease in the annual growth rate, then like most people, you’re being deceived by a quirk of human intuition. While small changes to the economic growth rate may not have noticeable effects in the short term, their long- term implications are absolutely astonishing.

Economist Tyler Cowen has pointed out in a Foreign Affairs article, “In the medium to long term, even small changes in growth rates have significant consequences for living standards. An economy that grows at one percent doubles its average income approximately every 70 years, whereas an economy that grows at three percent doubles its average income about every 23 years—which, over time, makes a big difference in people’s lives.” In his book Stubborn Attachments, Cowen offers a thought experiment to illustrate the real-​world implications of such “small changes” to the growth rate: “Redo U.S. history, but assume the country’s economy had grown one percentage point less each year between 1870 and 1990. In that scenario, the United States of 1990 would be no richer than the Mexico of 1990.”

Cowen gave the negative scenario in which the growth rate was 1 percent slower. US Citizens would have drastically shorter lifespans, less education, less healthcare, less safety from violence, more susceptibility to disease and natural disaster, fewer career choices, and so on. Now imagine the opposite scenario, in which US economic policy had just 1 additional percentage point of growth each year. The average American today would in all probability be living much longer, having much nicer housing, choosing from far more career opportunities, and enjoying more advanced technology.

Just imagine your income doubling, and what you could do for yourself, your family, or the charity of your choice with all that extra wealth. Something along those lines could have happened to most Americans. But instead, growth has been significantly slowed in the United States because taxes and regulations have constantly disincentivized and disallowed new innovations.

At the margins, many dying of preventable diseases could have been cured, many who spiraled into homelessness could have accessed the employment opportunities or mental health treatment they needed, and so on. While economic fortune seems like a luxury to those who already enjoy material comfort, there are always many at the margin for whom the health of the economy is the difference between life and death.

These are among the reasons that Harvard University economist Gregory Mankiw concludes in his commonly used college textbook Macroeconomics that, “Long-​run economic growth is the single most important determinant of the economic well-​being of a nation’s citizens. Everything else that macroeconomists study — unemployment, inflation, trade deficits, and so on — pales in comparison.”

When we think of the future our children or grandchildren will live in, depending on our choices between even slightly more or less restrictive economic policies today, we could be plausibly looking at a future of widespread and affordable space travel, life-​changing education and remote work opportunities in the metaverse, new sustainable energy innovations, a biotechnological revolution in the human capacity for medical and psychological flourishing, genome projects and conservation investments to revive extinct and protect endangered species, and countless other improvements to the human condition. Or we could be looking at a drawn-​out stagnation in poverty alleviation, technological advancement, and environmental progress. The difference may well hinge on what looks today like a tiny change in the rate of compounding growth.

At the broadest level, more wealth in the hands of the human species represents a greater capacity of humans to chart their course through life and into the future in accordance with their values. Like all profound and far-​reaching forms of change, economic growth has a wide range of consequences, some intended and others unintended, many desirable and many others undesirable. But it is not a random process. It is directed by the choices of individuals, and allocated by their drive to devote more resources and more investment into those things they view as worthwhile. Ever since the Scientific Revolution, the Enlightenment, and the Industrial Revolution, the investment in human values has been on balance a positive sum game, in which one group’s gains do not have to come in the form of another group’s losses. This is demonstrated by the upward trends in human flourishing since the global rise in exponential economic growth. Indeed, it is intrinsic to the fundamental difference between a growing and a shrinking or stagnant economy: In a growing economy, everyone can win.

Fin Whales Making Strong Comeback in the Southern Ocean

“For a long time, there has been great uncertainty about whether the fin whale has managed to recover after the industrial whaling in the Southern Ocean in the first half of the 20th century.

Now marine scientists can confirm the ‘comeback’ of fin whales in a key region of the Southern Ocean. Whale counts that have recently been presented in a scientific article show a record number of fin whales in the Scotia Sea in the Southwest Atlantic sector of the Southern Ocean.

– It is simply sensational. The results show over 50,000 fin whales in the Scotia Sea alone. That is more than three times higher than previously estimated for the entire Southern Ocean, says marine scientist Martin Biuw.”
