Our Digital Footprint: Crafting a Sustainable Web

Have you ever thought about the environmental impact of our online activities? It’s pretty surprising how much energy goes into supporting our digital lives. Today, we’re exploring the concept of digital sustainability, the environmental cost of internet usage, and actionable steps individuals and businesses can take to reduce their digital footprint. 

Digital Sustainability- What’s That?

Digital sustainability refers to practices that minimize the environmental impact of digital technologies. As we spend more time online, the energy needed to keep everything running smoothly grows, too. Sustainable practices help mitigate this impact, making a noticeable difference for both the planet and our communities.

The Environmental Impact of Internet Usage

When we hear the word “internet,” most of us imagine virtual and wireless worlds hovering in an intangible cloud. As a result, we might not fully consider the environmental impact of digital technology. The reality is that the infrastructure needed to support our digital world is immense and very real. From data centers to cooling systems, the infrastructure supporting our online activities is a major contributor to carbon emissions. Typically, when we link digital technology and climate issues, it’s often in the context of how technology can help address the climate crisis—through climate modeling, smart city innovations, or sharing vital climate research.

Rarely do we make the correlation that many of our modern-day conveniences have a direct impact on our planet. For instance, the energy required to run data centers and power our devices significantly contributes to greenhouse gas emissions, which impacts global warming. The internet and its infrastructure generate around one billion tons of greenhouse gasses annually.  Notably, the carbon footprint of the Internet and its supporting systems accounted for about 4% of global greenhouse gas emissions just a few years ago. That number has likely increased significantly since then.

According to the IEA’s report Digitalisation and Energy:

“More than 3.5 billion people, or nearly half the global population, now use the internet – up from only 500 million in 2001. About 54% of households now have internet access at home. In the last five years, global mobile broadband subscriptions increased threefold and surpassed 4 billion active subscriptions in 2017. There are now more mobile phone subscriptions (7.7 billion) than people in the world.”

The Challenge of Energy Consumption in Data Centers

Power-Hungry Data Center Infrastructure

Data centers are like the engines of the internet, housing servers that store and process all our data. These facilities consume enormous amounts of electricity to power and cool the servers, making them one of the largest energy consumers within the digital ecosystem. “Data Center Alley” in Northern Virginia, already known for having the highest concentration of data centers globally, is rapidly expanding. Seventy percent of the world’s internet traffic flows through Loudoun County, alone.

“Data centers serve as factories of the information age; their 24/7 operation makes online browsing, streaming and communication possible, but delivering all this data requires a tremendous amount of electricity. The explosive demand of internet-based platforms and services has fueled a dramatic expansion in both the size and number of data centers, making them collectively one of the largest sources of new electricity demand globally.” Greenpeace ‘Clicking Clean’ campaign

Reliance on “Dirty” Electricity Grids

Many data centers rely on conventional electricity grids powered by fossil fuels. This dependency results in substantial carbon emissions, contributing to climate change. Transitioning to renewable energy sources is crucial for reducing the carbon footprint of data centers. But this is only part of the solution. A new Meta data center in The Netherlands has committed to using 100% renewable energy, but doing so will take up almost 10% of the entire country’s wind energy supply.

The Carbon Footprint of Data Centers

The carbon footprint of data centers is staggering. According to recent studies, data centers account for about 1% of global electricity demand, with projections indicating this could rise significantly. This highlights the urgency of adopting sustainable practices in the industry.

The Elemental Irony: Cooling the Cloud

The Role of Air Conditioning in Data Centers

Air conditioning is essential for maintaining optimal temperatures in data centers, preventing server overheating. However, the energy required for cooling is immense, further increasing the environmental impact of these facilities. 

To maximize efficiency, all servers are lined up in aisles with their fans pointing in the same direction. This configuration creates a “hot aisle,” where heated air is collected, cooled, and then directed into the adjacent “cool aisle.” The air conditioning system also maintains a precise humidity level to ensure the hard drives’ integrity.

Impact of Cooling Systems on Energy Consumption

Cooling systems are responsible for a significant portion of energy consumption in data centers. Data centers currently consume about 1% of the world’s electricity. Furthermore, this energy consumption is projected to quadruple by 2030. Innovative cooling technologies and energy-efficient designs are necessary to reduce this burden and enhance overall sustainability. 

Comparison of the Carbon Footprint of Data Centers with Other Industries

When comparing the carbon footprint of data centers to other industries, the numbers are alarming. “The Cloud now has a greater carbon footprint than the airline industry. A single data center can consume the equivalent electricity of 50,000 homes,” says Anthropologist Steven Gonzalez Monserrate in his article The Staggering Ecological Impacts of Computation and the Cloud for the MIT Press Reader.

Redefining Sustainability in the Digital Age

Discussion on the Urgency of Addressing Digital Sustainability

Addressing digital sustainability is not only important but urgent. A 2021 study published in Nature Sustainability suggests the Information and Communications Technology (ICT) sector could account for up to 20% of global carbon emissions by 2025 ([Hickman et al., 2021]). As the digital economy continues to grow, failure to implement sustainable practices could exacerbate environmental degradation. We believe it requires a collaborative collaborative effort to ensure a sustainable digital future.
