The argument could be made that data centers are a major driving force in the energy transition to renewables...Siemens
With the backdrop of a global energy crisis, it’s perhaps a good time to discuss the real energy cost of data centers, why they’ve become one of the world’s fastest-advancing industries, and how an argument could be made that they are, in fact, a major driving force in the energy transition to renewables.
Firstly, let’s consider their growth. Between 2015 and 2021, internet users have increased by 60%, and internet traffic by 440%, according to IEA data. But despite a rise in workload for data centers of 260% in the same time period, global energy use attributed to data centers has remained relatively flat, representing just a 10% increase.
Decoupling service demand from energy
This decoupling of energy usage from service demand is hugely significant. It’s being driven by rapid innovation of digital technology in data centers, allowing the industry to offset huge increases in demand with improved infrastructure efficiency.
In short, we are building more and more digital capacity, modernizing legacy infrastructure and meeting the growth, but in real terms we’re not using much more energy than we were five years ago.
The real challenge here is how we limit the environmental impact of global internet use. We should be honest; there is an impact, there always will be and we need to continue to use technology and commercial innovation to mitigate it.
Looking at the lifecycle of a datacenter, we see that more than 85% of the carbon impact today comes from operations. There is also certainly an impact during construction and it’s also significant – certainly worthy of mitigation – but net-zero construction will not address the larger part of the challenge: the carbon impact of running the facility for 20 years or more.
Driving the energy transition
Enter the concept of energy mix. A data center’s carbon performance is broadly a function of the energy mix in the location in which it’s operating. There are some exceptions, where operators take the responsibility to generate power on-site using renewables or gas, but largely speaking local grids power data centers.
The data center industry is a major buyer of PPA agreements for renewable energy, and this has a significant impact on the energy mix. In 2021, Amazon and Microsoft were the two largest corporate buyers of renewable energy through PPA; to a degree, the data center industry is helping to drive decarbonization by underwriting a significant proportion of grid-scale, carbon-free energy for industry.
This can catalyze a whole ecosystem at a national level, and also demonstrates to the broader industrial base that critical loads can reliably move to renewables.
Growing adoption of renewable energy – and higher levels of infrastructure redundancy at the IT level – are also leading to new design best practices in data centers. Battery Energy Storage Systems (BESS) are replacing diesel gensets as short-term backup power supply, for example.
With energy markets increasingly interconnected, data centers adopting BESS can generate unprecedented revenues by running in island mode in case of outages (without emitting carbon dioxide from diesel generators) or stabilizing the frequency of the grid.
Beyond carbon reduction
The quest for efficiency is as important as ever, and the discipline of energy management has a massive effect on the operational impact of a data center. Innovation in technology for managing environmental conditions inside a data center is having a significant impact on energy consumption.
We know that 20% to 40% of a data center’s energy use can go towards cooling and ventilation, and this mechanical load is a prime area for optimization through technology. White space cooling is a good example. Our technology for this – a white space cooling optimization solution – uses an advanced machine-learning model to analyze the effect of cooling on specific areas of a data center, creating an influence map to limit energy use to only what’s necessary.
AI engines like this can make a significant difference to a data center’s energy costs; it’s one of the reasons the new Greenergy data center in Estonia is the most energy efficient in the Baltic region.
Building elasticity into data center design is also a key factor in reducing the sector’s energy consumption and cost. Through intelligent design, instrumentation, control and automation, a data center can enable and disable capacity when it’s needed, rather than constantly running circuits and networks with no work to do.
In addition to preventing the over-provision of infrastructure, this is crucial at times of the year where additional capacity is needed to cover short peaks in demand. Black Friday and the Christmas period are a perfect example; with better mechanical, electrical and automation design we can dynamically reduce or increase data center infrastructure resources, enabling them to reliably run closer to their capacity for short periods of time.
The future?
Digitalization and the rise of internet access have delivered significant benefits to humanity, but we should be humble enough to acknowledge there is a sustainability impact. Our mission now is to continually and steadily drive that impact toward zero.
The data center industry has led by example by willingly investing in decarbonization, and has demonstrated that an ecosystem of technology companies can work together to measure, manage and fundamentally change an industry’s approach to energy through innovation. We must continue this pace of investment and innovation if we are to deliver the lowest possible impact of our digital lives on the environment.

Loneliness doesn’t just make people feel isolated. It alters their brain in ways that can hinder their ability to trust and connect to others. In The Neumayer III polar station sits near the edge of Antarctica’s unforgiving Ekström Ice Shelf during the winter, when temperatures can plunge below minus 50 degrees Celsius and the winds can climb to more than 100 kilometers per hour, no one can come or go from the station.
Its isolation is essential to the meteorological, atmospheric and geophysical science experiments conducted there by the mere handful of scientists who staff the station during the winter months and endure its frigid loneliness.
But a few years ago, the station also became the site for a study of loneliness itself. A team of scientists in Germany wanted to see whether the social isolation and environmental monotony marked the brains of people making long Antarctic stays.
Eight expeditioners working at the Neumayer III station for 14 months agreed to have their brains scanned before and after their mission and to have their brain chemistry and cognitive performance monitored during their stay. (A ninth crew member also participated but could not have their brain scanned for medical reasons.)
As the researchers described in 2019, in comparison to a control group, the socially isolated team lost volume in their prefrontal cortex — the region at the front of the brain, just behind the forehead, that is chiefly responsible for decision-making and problem-solving.
They also had lower levels of brain-derived neurotrophic factor, a protein that nurtures the development and survival of nerve cells in the brain. The reduction persisted for at least a month and a half after the team’s return from Antarctica.
It’s uncertain how much of this was due purely to the social isolation of the experience. But the results are consistent with evidence from more recent studies that chronic loneliness significantly alters the brain in ways that only worsen the problem.
Neuroscience suggests that loneliness doesn’t necessarily result from a lack of opportunity to meet others or a fear of social interactions. Instead, circuits in our brain and changes in our behavior can trap us in a catch-22 situation: While we desire connection with others, we view them as unreliable, judgmental and unfriendly.
Consequently, we keep our distance, consciously or unconsciously spurning potential opportunities for connections. Loneliness can be difficult to study empirically because it is entirely subjective. Social isolation, a related condition, is different — it’s an objective measure of how few relationships a person has.
The experience of loneliness has to be self-reported, although researchers have developed tools such as the UCLA Loneliness Scale to help with assessing the depths of an individual’s feelings. From such work, it’s clear that the physical and psychological toll of loneliness across the globe is profound.
In one survey, 22% of Americans and 23% of British people said they felt lonely always or often. And that was before the pandemic. As of October 2020, 36% of Americans reported “serious loneliness.”
Organizations and governments often attempt to help with loneliness by encouraging people to go out more and by setting up hobby clubs, community gardens and craft groups. Yet as the neuroscience shows, getting rid of loneliness isn’t always that simple.
A Bias Toward Rejection
When neuroscientists from Germany and Israel set out to investigate loneliness a few years ago, they expected to find that its neural underpinnings were like those of social anxiety and involved the amygdala. Often called the fear center of the brain, the amygdala tends to activate when we face things we dread, from snakes to other humans.
“We thought, ‘Social anxiety is associated with increased amygdala activity, so this should also be the case for lonely individuals,’” said Jana Lieberz, a doctoral student at the University of Bonn in Germany who was part of the research team.
Vegetable oils are found in thousands of products, from cosmetics and shampoo to cookies and other food products. They’re also used for cooking by billions of people and, in fact, are the food commodity that’s growing the fastest, with demand consistently higher than supply.
Current disruptions in the worldwide supply caused by weather issues, armed conflict, supply chain disruptions and labor shortages are resulting in higher prices, causing a ripple effect of sticker shock throughout the food economy, according to Amanda Leland of the Environmental Defense Fund.
Biofuels, widely used in Europe and whose demand is increasing, are likewise affected. Businesses with interests in these and other vegetable-oil-related markets need to take notice. With oil products in crisis, there’s an opportunity for new avenues of increasing supply, including indoor farming and replacing certain vegetable oils with other types of oils.
Current Disruptions
Russia’s invasion of Ukraine exacerbated the shortage of cooking oils, especially sunflower oil. Before the war, Russia and Ukraine produced approximately 75% (subscription required) of the world’s sunflower oil. With countries banning Russian imports and the conflict preventing Ukraine producers from harvesting, the supply predictions plummeted.
The next year’s harvest for Ukraine looks dismal due to the country’s disrupted transportation system, labor shortages and other related factors. This has caused ripple effects around the world where sunflower oil is used, including in the U.K. and Germany.
The supply of vegetable oils is impacted by labor shortages due to Covid and weather issues as well as geopolitical conflicts. For palm oil producers in Malaysia, the second largest market provider, there’s an ongoing shortage of both laborers and fertilizer, hampering production (subscription required).
Meanwhile, in South America, where over 50% of the world’s soybeans are grown, labor problems and ongoing drought are severely impacting production. This will require food producers to adjust as soybean oil prices reach a nine-year high.
The Local Indoor Farming Opportunity
This problem has created an opportunity for traditional farmers. Farmers can fill the current need by starting to produce other vegetable oils such as olive oil, flaxseed oil, coconut oil, avocado oil, grapeseed oil and sesame oil, which can be used as substitutes for vegetable oils.
Controlled Environment Agriculture (CEA) is also a solution. The infrastructure required for a controlled indoor grow environment can be easily built or adapted from existing structures, and it uses far less water than a traditional environment. This can allow for optimal results in places where access to water and fertilizer are limited and as we continue to face issues of drought.
Advanced indoor grow operations use hydroponics and artificial lighting to better control growing conditions and offer plants the nutrients and light levels they require. Automated tools can match energy, water, fertilizer, air flow and other data points to increase yields and profits. (Full disclosure: My company, Pangea, produces software and smart lighting solutions for indoor farming.)
A data-driven approach with centralized controls makes the oil-yielding indoor grow market financially viable, especially in the face of global conflicts and labor shortages. CEA can localize the growing of soybeans, palm or other plants. This will shorten supply chains and provide a long-term answer to regional issues driving price inflation and disruptions for providers and the end consumer.
One form of indoor agriculture is vertical farming, which produces foods in stacked layers instead of a field or greenhouse, allowing for a smaller footprint. This technique is not new but has existed for hundreds of years. Contemporary vertical farming uses LED technology instead of natural sunlight; the integration of light and technology gives precise data to farmers to reduce the human error that comes along with growing crops.
A market report from Technavio, a leading global technology research and advisory company, predicts a compound annual growth rate (CAGR) of nearly 22% from 2021 to 2026 for the global vertical farming market due to increased demand and innovations in farming practices. The report points to the massive opportunity for localized indoor farming production of oil-yielding plants and the chance to address some of the supply issues with vegetable oils.
Techniques like these demonstrate how AgTech is quickly advancing to help secure a better future for farmers and consumers alike.
Plants protect themselves from environmental hazards like insects, drought and heat by producing salicylic acid, also known as aspirin. A new understanding of this process may help plants survive increasing stress caused by climate change.
UC Riverside scientists recently published a seminal paper in the journal Science Advances reporting how plants regulate the production of salicylic acid. The researchers studied a model plant called Arabidopsis, but they hope to apply their understanding of stress responses in the cells of this plant to many other kinds of plants, including those grown for food.
“We’d like to be able to use the gained knowledge to improve crop resistance,” said Jin-Zheng Wang, UCR plant geneticist and co-first author on the new study. “That will be crucial for the food supply in our increasingly hot, bright world.”
Environmental stresses result in the formation of reactive oxygen species or ROS in all living organisms. Without sunscreen on a sunny day, human skin produces ROS, which causes freckles and burns. High levels of ROS in plants are lethal.
As with many substances, the poison is in the amount. At low levels, ROS have an important function in plant cells. “At non-lethal levels, ROS are like an emergency call to action, enabling the production of protective hormones such as salicylic acid,” Wang said. “ROS are a double-edged sword.”
The research team discovered that heat, unabated sunshine, or drought cause the sugar-making apparatus in plant cells to generate an initial alarm molecule known as MEcPP.
Going forward, the researchers want to learn more about MEcPP, which is also produced in organisms such as bacteria and malaria parasites. Accumulation of MEcPP in plants triggers the production of salicylic acid, which in turn begins a chain of protective actions in the cells.
“It’s like plants use a painkiller for aches and pains, just like we do,” said Wilhelmina van de Ven, UCR plant biologist and co-first study author.
The acid protects plants’ chloroplasts, which are the site of photosynthesis, a process of using light to convert water and carbon dioxide into sugars for energy.
“Because salicylic acid helps plants withstand stresses becoming more prevalent with climate change, being able to increase plants’ ability to produce it represents a step forward in challenging the impacts of climate change on everyday life,” said Katayoon Dehesh, senior paper author and UCR distinguished professor of molecular biochemistry.
“Those impacts go beyond our food. Plants clean our air by sequestering carbon dioxide, offer us shade, and provide habitat for numerous animals. The benefits of boosting their survival are exponential,” she said.
Investors with allocations to emerging market debt now need to understand the true impact on developing economies of long run factors like climate change and human capital development.
Governments everywhere are racing to lock in historically low borrowing costs by issuing ever longer dated debt – in recent years Mexico and Argentina even managed to sell century bonds. That presents several new challenges for fixed income investors. Particularly those who own emerging market bonds.
Not only do bondholders have to weigh the usual near-term factors like political, economic and commodity cycles but, in lending money to sovereigns over such extended periods, they now also have to consider the impact of longer term trends such as climate change and social development. Both can affect creditworthiness in profound ways.
This has called for new approaches to investment thinking. Economic and financial forecasts are having to be recast with climate dynamics in mind. Meanwhile, modelled pathways of climatic change are themselves subject to expectations about future technological change as well as the evolution of political thinking in these countries. The number of moving parts only grows as investors realise they also have a role to play in shaping how governments approach making their economies sustainable and low-carbon.
It’s a complex problem. But not an insurmountable one.
The greening of EM debt
In 2015, some 17 per cent of emerging market hard currency debt had a maturity of 20 years or more. By the start of 2021, that proportion had grown to 27 per cent. Even local currency denominated emerging market debt, which tends to be shorter-dated, has moved along the maturity curve. Over the same time period, the proportion of local currency debt with a maturity of five years or longer had risen 11 percentage points to 58 per cent (1).
That shift reflects growing demand for yield from investors starved of income. But at the same time, bondholders have recognised the importance of taking a long-term view on environmental issues. This is apparent in both the appetite for green bonds – capital earmarked for environmental- or climate-related projects – and, more generally, bonds that fall under the environmental, social and governance (ESG) umbrella.
Governments are happy to meet that demand. Increasingly, they recognise the need to make efforts to mitigate climate change, and given that emerging market economies make up half the world’s output, they have a significant role to play in meeting global greenhouse gas emissions goals.
In the five years to the end of 2020, annual issuance of green, social and sustainability bonds by emerging market governments grew nearly four-fold to USD16.2 billion (2). And demand is only increasing. For instance, in the first few weeks of January, Chile met 70 per cent of its expected USD6 billion debt issuance for 2021, all in green and social bonds and it plans only to issue sustainable and green bonds during the remainder of the year (3). In September 2020, Egypt became the first Middle Eastern government to issue a green bond. It raised USD750 million to finance or refinance green projects. Investors were enthusiastic – the bond was five times oversubscribed (4).
And generally, these bonds have longer maturities than conventional fixed income securities. Some 46 per cent of USD36.8 billion of outstanding emerging market ESG bonds priced in local currency terms have a maturity of more than 10 years, while for emerging markets hard currency ESG bonds, it’s 41 per cent of USD12.9 billion of outstanding bonds (5).
These bonds allow investors to track performance, while green agendas can also help governments to improve their credit ratings, which then lifts the value of their debt, thus rewarding bond holders.
Overall, green bonds generate positive feedback effects. The rising volumes of green and sustainable bond issuance highlights investors’ willingness to take more of a long-term approach to EM investing. But at the same time, governments are being made more accountable – in order to issue these bonds, governments are having to publish their sustainability frameworks in greater detail. This additional accountability helps to mitigate political risks that are a key consideration in EM investing. Investors, however, will need to analyse and monitor developments closely to ensure proceeds are used as intended.
Indeed, green bonds are the most exciting development in emerging market financing for decades and, we think, will have an equivalent impact to the Brady bonds of the 1980s (6) – albeit this is dependent on improved disclosure and monitoring and industry standardisation of green labels.
Climate change matters (especially in EM)
For all the sovereign issuance of green bonds so far, a great deal more funding will need to be raised to limit climate change. Globally it will cost between USD1 trillion and USD2 trillion a year in additional spending to limit global warming, some 1 per cent to 1.5 per cent of worldwide GDP, according to the Energy Transitions Commission (7). And a significant part of those costs will need to be borne by emerging economies, not least because they are likely to suffer most.
By the end of this century, unmitigated climate change – entailing warming of 4.3° centigrade above pre-industrial levels – would cut per capita economic output in major countries like Brazil and India by more than 60 per cent compared to a world without climate change, according to a report by Oxford University’s Smith School sponsored by Pictet (8). Globally, the shortfall would be 45 per cent.
Limiting warming to 1.6° C would sharply reduce that hit to roughly 27 per cent of potential output per capita for the world as a whole, albeit with considerable variation among countries. While those in the tropics countries would be hit hard by the effects of drought and altered rainfall patterns, those in high latitudes, like Russia, would be relative winners as ports become less ice-locked and more territory is opened up to extractive industries and agriculture. And though China would suffer smaller overall losses than average, its large coastal conurbations would be subject to depredations caused by rising sea levels.
Integrating risks
As these effects are felt, investors will grow increasingly wary of lending to vulnerable countries. And climate change is already having an impact on developing countries’ credit ratings. In 2018, rating agency Standard & Poor’s cited hurricane risk when it cut its ratings outlook on the sovereign debt issued by the Turks and Caicos (9).
Investors could expect climate-related events, like droughts, severe storms and shifts in precipitation patterns, to push up output and inflation volatility in emerging economies during the next ten to 20 years, according to Professor Cameron Hepburn, lead author of the Oxford report.
That would represent a significant reversal for emerging market sovereign borrowers. Since the turn of the century the relative rate of growth and inflation volatilities between emerging and developed markets has halved (10), which, in turn, has reduced the risk faced by investors. Rising economic volatility would feed into sovereign risk assessments, eroding their credit profiles.
Other research from the Oxford team highlights the choices countries will need to take to remain on the path towards building a greener economy (11).
At Pictet Asset Management, we already use a wealth of ESG data – from both external and internal sources –as part of how we score countries. The environmental factors we monitor include air quality, climate change exposure, deforestation and water stress.
Social dimensions include education, healthcare, life expectancy and scientific research. And governance covers elements like corruption, electoral process, government stability, judicial independence and right to privacy. Together these factors are aggregated to become one of six pillars in the country risk index (CRI) ranking produced by our economics team.
Level playing fields
We believe that ESG considerations are inefficiently reflected in emerging market asset prices. This is a consequence of the market still being at an early stage in its understanding and application of ESG factors and analysis. There is also a lack of consistent and transparent ESG data for many emerging countries. We believe that using an ESG score alone is simply not enough. Having a sustainable lens through which to examine emerging market fundamentals helps us to mitigate risk and unearth investment opportunities. We use our own ESG data and analysis and engage with sovereign bond issuers to help bring about long-term change.
Emerging market economies vary hugely in their degree of development. This complicates how investors should weigh their ESG performance – after all, richer countries are more able to make the ESG-positive policy decisions that often have high front end costs for a long tail of benefits, such as shutting down coal mines in favour of solar power.
Applying the most simplistic approach to ESG – investing on the basis of countries’ ESG rankings – would squeeze fixed income investors out of the poorest developing countries, even if they are implementing the right policies to improve their ESG standing. Instead, it’s important for investors to recognise what is possible and achievable by poorer countries and allocate funding within those constraints – understanding countries’ direction of travel in terms of ESG is critical to analysing their prospects.
One solution we are implementing at Pictet AM is to weigh ESG criteria against a country’s GDP per capita. So, for example, under our new scoring system, Angola does well on this adjusted basis despite having a low overall ranking. And the reverse is true for Gulf Cooperation Council member states.
Dynamic approaches
How governments react to long-term issues like climate change or to the challenge of developing their human capital will influence their economies’ trajectories and, ultimately, play a role in their credit ratings. Those long-term decisions are only growing in importance, not least given the scale of fiscal policies implemented in the wake of the Covid-19 pandemic. Tracking these spending programmes – through, say, the likes of the Oxford Economic Stimulus Observatory (12) – then becomes an important step towards understanding the ESG pathways governments are likely to follow.
Countries with good, well-structured policies are likely to see their credit ratings improve, which attracts investors, drawing funding into their green investment programmes and ultimately driving a virtuous investment cycle.
Engaged investors
All this implies that investors have an active role to play – they can’t just passively allocate funding based on index weightings or be purely reactive to policymakers’ decisions. The most successful investors will help steer governments towards the path that boosts their credit ratings, gives them most access to the market and improves the fortunes and potential of citizens.
Like, for instance, explaining how electricity generated by wind turbines or solar can prove to be more cost-effective over the long term if financed by green bonds than ostensibly cheaper coal extracted from a mine paid for with higher yielding conventional debt. Or how fossil fuel investments could prove to be major white elephants as these sorts of polluting assets become stranded by shifts towards cleaner energy production.
Or that failing to invest enough in education is a false economy that over the long run will fail to make the most of human capital and thus depress national output – something we raised with the South African government after our meetings with our on-the-ground charitable partners in the country. To that end, The World Bank produced in 2020 a timely guide on how sovereign issuers can improve their engagement with investors on ESG issues (13).
This sort of intensive analysis – using everything from long run macro models down to meetings with leaders of youth clubs in impoverished districts – can also help to paint a rounded picture of what’s happening in a country. For instance, it helped to ensure that we weren’t caught off guard by the shift to populism in Argentina ahead of their last elections and allowed us to trim our positions in the country.
For emerging market investors, ensuring all of these cogs mesh correctly is a difficult proposition, especially given that the parts are moving all the time, many driven by forces that will develop over many decades. But by using the full breadth of analytical tools, independent research and shoe leather fact-finding, it’s possible to gain a deeper and more profitable insight into these markets than a simple reading of credit ratings or index weightings offers.
And, at the same time, influence policy makers to champion their country’s sustainable initiatives. Taking a sustainable approach to growth and issuing related bonds, emerging economies can fundamentally change their prospects for the better. It has the potential to be revolutionary for emerging markets and exhilarating for those of us who invest in them.
