Supported by the Julia R. Brown Education and Research Fund, MAS Climate Science and Policy student Greta Schultz traveled to the summit to gather insights for her master’s capstone on sustainable data center development. The conference highlighted power availability as the main growth constraint, the outsized climate impact of embodied carbon, and the importance of water stewardship—findings that directly inform her GIS‑based analysis and future work in low‑carbon digital infrastructure. This experience sharpened her perspective on balancing reliability with decarbonization and expanded her professional network in the energy systems and data center community.
Overview
The 4th US Data Center Sustainability & Energy Efficiency Summit brought together industry leaders, utilities, researchers, and sustainability practitioners to discuss the challenges of rapidly growing data center demand in the United States. With AI-driven compute accelerating load growth, the conference focused on how data centers can balance reliability, cost, and sustainability amid increasing grid and water constraints.
Key Takeaways and Relevance to My Research
A central theme of the summit was that power availability is becoming the primary constraint on data center growth, rather than land or capital. Multiple speakers emphasized that AI workloads are driving unprecedented electricity demand, putting pressure on already congested grids and reshaping siting and planning decisions.
The conference directly informed my master’s capstone research on sustainable data center development. Several sessions highlighted that the largest climate impacts of data centers occur upstream, particularly through embodied carbon in construction materials and hardware manufacturing. Speakers from organizations such as the Global Electronics Council and Compass Datacenters underscored the importance of Environmental Product Declarations (EPDs) and procurement choices as high-impact decarbonization tools.
Water use and local environmental impacts were also recurring topics. Discussions on water stewardship reinforced that data center sustainability is highly location-dependent and must account for regional water stress, community impacts, and long-term resilience—an insight that aligns closely with my use of GIS-based analysis in my capstone project.
Most Impactful Insights
One of the most striking aspects of the summit was the tradeoff between sustainability goals and reliability requirements. While long-term decarbonization remains a priority, many near-term solutions rely on interim measures such as natural gas, backup generation, and hybrid microgrids to ensure uptime.
Another notable takeaway was the growing emphasis on waste heat as a resource, with examples of waste heat reuse and hybrid systems that could enable data centers to support carbon removal or water production rather than simply dissipating excess heat.
Looking Ahead
This experience strengthened my interest in working at the intersection of energy systems planning, climate strategy, and data center sustainability. I plan to integrate these insights into my capstone research, particularly around power constraints, embodied carbon reduction, and water stewardship, and to apply them in a future career focused on building resilient, low-carbon digital infrastructure.
