The global data center market is experiencing unprecedented growth, driven by the explosion of cloud services, artificial intelligence applications, and enterprise digital transformation. According to JLL, colocation vacancies have dropped to historic lows, driving rent increases of up to 50% in certain markets. While this trend highlights the extraordinary demand for digital infrastructure, it also reveals an underlying challenge: the energy footprint of data centers. As operators grapple with higher rents and limited capacity, energy management is becoming a central pillar for ensuring both financial competitiveness and environmental responsibility.
Vacancy rates in colocation data centers are shrinking rapidly across North America. Hyperscalers and enterprises alike are competing for scarce capacity, fueling a surge in rental prices. For example, in Northern Virginia, the world’s largest data center hub, demand continues to exceed supply, leading to delays in new construction and fierce competition for existing space. The result creates financial pressure while also adding a compounding effect on energy demand. Each new tenant adds to the facility’s load, requiring greater resilience from both operators and local utilities.
The ripple effect is clear: as rents climb, tenants are more sensitive to total cost of occupancy, including energy bills. For colocation providers, the ability to optimize electricity consumption and deliver sustainable power sourcing has become a differentiator in a crowded and expensive market.
Data centers currently consume about 1.5% of global electricity consumption in 2024, but new analysis from the International Energy Agency highlights that artificial intelligence workloads could significantly accelerate demand growth. The IEA projects that electricity use from AI and the associated infrastructure could rise dramatically in the coming years, with global AI-related demand potentially rivaling the energy footprint of entire countries if efficiency measures are not adopted. In many regions, power availability is already the limiting factor in expanding facilities. Rising energy prices only amplify the challenge, adding a volatile cost layer to an already expensive asset class.
Moreover, enterprises are under increasing pressure to meet net-zero and ESG commitments. Tenants often require colocation providers to source renewable electricity or demonstrate lower carbon intensity in operations. For example, corporate clients seeking Science Based Targets initiative (SBTi) compliance expect their digital infrastructure to align with clean energy objectives. This has elevated energy strategy from an operational concern to a boardroom-level priority.
In response to these challenges, data center operators are deploying a range of advanced energy management strategies. Key approaches include:
These measures not only reduce operating expenses but also strengthen tenant relationships. Clients are increasingly prioritizing data center providers that can demonstrate both cost efficiency and environmental responsibility. Energy-smart operations can therefore translate directly into higher occupancy and reduced churn.
The challenge is particularly acute in fast-growing digital hubs. In Silicon Valley, limited power availability has slowed down the development of new facilities. Meanwhile, Northern Virginia faces grid strain due to explosive growth in data center demand. In all these cases, smarter energy management is a competitive advantage and often the prerequisite for continued expansion.
By improving efficiency and sourcing renewable power, operators can extend the capacity of existing assets and defer costly infrastructure investments. This approach also supports broader regional and national decarbonization goals. Tenants are increasingly drawn to providers who can guarantee not only availability but also alignment with their climate commitments.
The surge in colocation demand and the corresponding rise in rental costs highlight an urgent truth: the next great constraint for data centers is energy. With global electricity use already significant and demand accelerating, operators must adopt smarter energy management strategies to thrive. Efficiency improvements, renewable procurement, and resilient infrastructure will not only lower costs but also position providers as leaders in a market defined by scarcity and sustainability. In the era of digital infrastructure, energy is not just an expense, it is a strategic asset.

Virtual Power Plants are emerging as a cost-effective way to balance electricity grids by aggregating flexible demand and distributed energy resources. By 2028, California alone could save over 200 million dollars through VPP adoption, showing how households and businesses are becoming active partners in the energy transition.
