The digital world is booming—and so is data center energy consumption. As demand for more computing power grows, so does the pressure to reduce environmental impact.
Nearly all tech companies now boast sustainability goals, and the market for green data centers is projected to grow at a compound annual growth rate (CAGR) of 16.7% from 2023-2032.
Although embracing eco-friendly practices is a challenge in this industry, emerging technologies and trends are helping data centers take real steps toward achieving their sustainability goals. Here are five trends that are currently shaping data center sustainability objectives and strategies.
1. Adoption of Varied Green Energy Strategies
One popular approach to lowering environmental impact is switching from traditional fossil fuels to greener energy sources.
Renewables such as solar, wind and hydrogen fuel cells are the fastest-growing source of electricity for data centers. By 2035, renewables are projected to make up around half of the global energy demand for data centers. Data centers can employ varied strategies to access renewable energy, including power purchase agreements (PPAs) with local utility providers and on-site energy generation and microgrids.
Renewables aren’t always a feasible option as the sole source of energy. As Reuters noted, the incredible demand for data centers due to technological developments is likely to outpace renewable energy infrastructure. In these cases, natural gas presents a less carbon-intensive alternative to coal.
Data centers are also taking advantage of nuclear energy. The use of nuclear energy is expected to increase exponentially over the next decade to meet the growing data center energy demand.
In addition to driving demand for data centers, AI is also driving developments in data center technology. When it comes to sustainability, Internet of Things (IoT) sensors and AI-powered analytics allow for real-time energy savings.
AI models can help data centers optimize areas such as:
By tightening up operating efficiency in these areas, data centers can decrease energy and
Many data center organizations are broadening their focus to include not only their direct environmental impact but also more indirect issues embedded in the value chain. These indirect sources of carbon emissions are known as Scope 3 emissions.
Organizations are increasing their reporting of these emissions and upping their commitment to reduce them. To accomplish this, they are deploying carbon accounting platforms that trace emissions from hardware lifecycle to energy source. Many are also opting for low-carbon building materials to reduce emissions throughout data center development.
But why the growing focus on Scope 3 emissions? In some regions, environmental, social and governance (ESG) regulations now require Scope 3 reporting. In other cases, upstream frameworks encourage data centers to deliver deeper carbon disclosures that include Scope 3 emissions. Overall, data centers are recognizing that their total carbon footprint extends well beyond the energy they consume.
Increasing demand for data centers means an ever-growing number of data center construction and expansion projects. Even before operations are up and running, this construction phase represents a significant opportunity for data center sustainability wins or losses.
Many eco-conscious organizations are turning to modular infrastructure to get the job done. Modular construction has been steadily growing in popularity in the data center industry and is expected to continue growing at a CAGR of 17.4% from 2025-2030.
Among other advantages, modularity offers inherent sustainability benefits, including:
Overall, off-site modular builds offer a smarter, more efficient alternative compared to traditional construction methods, helping data centers start on the right foot when it comes to sustainability and remain agile for the future.
