Data centers presently account for almost 2% of global energy use. While concerns regarding the exponential growth of data center energy consumption have persisted for over a decade, hyperscale cloud service providers have effectively covered this issue in collaboration with industry vendors through the use of IT virtualization & the optimized utilization of power & thermal management networks. Enterprises, which have historically been less efficient in managing data centers than CSPs, have also increasingly migrated their workloads & applications to the cloud.
The COVID-19 pandemic’s rapid acceleration of digital transformation led to a flow in data center demand, raising concerns about the future energy use of data centers. As a result, data center service gives customers, regulators, & investors all demanding environmentally sustainable growth from the industry.
Data center sustainability is a tool for understanding the total cost of operations & a method to reduce these costs through innovation. The technological requirements associated with the maintenance & operations of a facility play a major role in determining the overhead & emissions associated with delivering data center services. This includes IT devices, the underlying network grid used to transfer and maintain operational data, & the thermal & electrical systems used to run all of this equipment.

Sustainability defined
Pursuing a more cost-efficient and ecologically sound operational model, sustainable design principles can be leveraged to meet key organizational goals. Regardless of the scale or scope of the problem, the benefits of incorporating sustainability into operations will have important implications on an operational system’s overhead and economic viability. This is the case whether the choices for sustainability are applied to the selection of a new facility or the improvement of an existing one.
At its core, data center sustainability can be described as both a perspective used to evaluate operating costs & as a process to optimize data center facility systems: sustainability as a metric and sustainability as a model for design.
The hardware & software systems required for data center operations rely on high-demand architectures both in terms of power usage & staffing resources. These are added with IT devices, processing & data storage systems, the underlying network grid utilized to transfer & maintain this operational data, and the thermal and electrical systems use to run everything.
Understanding sustainability as a metric, the net cost of operating these systems can be rationalized based on power consumption & carbon use. In this way, a facility & its constituent hardware can be described as more or less sustainable based on their net output compared to the emissions required to give that output. Here, the notion of a cost analysis that incorporates emissions becomes a useful tool in evaluating the “actual” bottom line of operations.
Using the second definition of sustainability, the practice or principled design of key operational subsystems, the process of identifying sustainable alternatives depends on the important requirements of a facility. These requirements will lead to a budget in terms of power, thermal capacity, & data management that can be used to gauge the success of sustainable practices.
Sustainability cost model
Data centers, in general, are businesses that must balance the cost of providing services with net profitability. The main factors in calculating cost are traditionally the cost of power & the cost of staff.
Power can be easily broken down into the energy requirements associated with the data center network: electrical, thermal, & networking. Similarly, the cost of staffing a data center can be broken down into the individuals needed to keep the systems operational: maintenance people, hardware specialists, & customer service staff.
However, when focusing on sustainability, there is a third factor that has become an increasingly significant liability in recent decades: environmental cost.
The cost to the environment associated with data center operations is a function of both the physical footprint of the data center and the energy requirements of the systems within it. Each of these factors can be calculated to determine the facility’s carbon footprint, which is a metric that assesses the total carbon required to build and operate a commercial system. This is true even in use cases where a new data center is not being constructed from the ground up but rather being modernized for great sustainability.
The net footprint of a facility or business can directly affect the profitability of a data center because it may impact power utility rates & carbon-specific taxes levied against the total emissions. Additionally, the footprint of a facility may help organizations determine whether there is major waste negatively impacting the operational bottom line. This may drive important decisions in terms of specific service providers: selecting one data center facility over another, selecting one power utility over another, or deciding how expansion & growth opportunities fit into the larger organizational requirements of a business.

Conclusion
Sustainable data center practices are no longer optional they are useful for building an energy-efficient, environmentally responsible digital network. By using green technologies, optimizing energy usage, & investing in renewable power, data centers can mainly minimize their carbon use while managing performance & usability. As demand for data continues to grow, accepting sustainability ensures not only long-term cost savings but also a commitment to a cleaner, more responsible future.
Did you know?
The data center industry has the potential to direct the way, becoming not only one of the first but also the top sectors to use ambitious sustainability goals. These goals range from attaining carbon neutrality and sourcing 100% renewable energy to reducing waste. By completing these objectives, the data center industry can use a complete sustainability framework as a blueprint for other sectors to match.
FAQ
