The Energy-Hungry Backbone of Our Digital World
Data centers, the backbone of our digital age, are power-hungry giants. According to Science, they account for about 1% of global electricity usage, and as generative AI drives demand, this figure is set to rise. As per Boston Consulting Group (BCG), in 2022 alone, U.S. data centers consumed 2.5% of the nation’s electricity.
In our previous blog, we delved into the crucial PPP relationship fostering sustainability in this sector (government, utility providers, and data center owners). Now, let’s explore the cutting-edge technologies and strategies fueling the green revolution in data centers.
Cutting-Edge Technologies Shaping the Future of Data Centers
Renewable Energy Integration
Data centers are major consumers of electricity, and integrating renewable energy sources is a pivotal step towards sustainability. Per the US Department of Energy, the largest data centers with tens of thousands of devices require over 100MW of power, which is enough to power approximately 80,000 households.
As internet usage increases, not to mention Generative AI, so does the demand for data center services, raising concerns about the energy consumption. It's not all bleak. Companies are increasingly turning to solar, wind, and hydroelectric power to meet their energy needs. Google and Amazon have invested heavily in renewable energy projects to power their data centers.
Advanced Cooling Solutions
Cooling is one of the most significant energy expenses for data centers. Innovations in cooling technologies, such as liquid cooling and advanced airflow management, are reducing energy consumption and enhancing efficiency.
Energy Storage Systems
Energy storage solutions, such as lithium-ion batteries and emerging supercapacitor technologies, are critical for managing energy supply and demand. These systems can provide backup power during outages and help balance the grid during peak usage times, ensuring a reliable and sustainable power supply.
In 2022, data centers consumed 2.5% of the U.S.'s total electricity. By 2030, this is expected to triple to 7.5%, equivalent to the electricity usage of about 40 million U.S. homes—nearly a third of all U.S. households.
Strategies for Sustainable Data Center Operations
Green Building Design
Sustainable building designs incorporate energy-efficient materials and practices. Implementing LEED (Leadership in Energy and Environmental Design) certification standards ensures that data centers minimize their environmental impact through efficient resource use and sustainable construction practices. LEED is the world’s first green building rating system to address data centers.
As of 2023 there were over 105,000 LEED-certified buildings and over 205,000 LEED-accredited professionals in 185 countries worldwide. Washington D.C. consistently leads in LEED-certified square footage per capita, followed in 2022 by the top-ranking states of Massachusetts, Illinois, New York, California, and Maryland.
Efficient Resource Management
Adopting resource management strategies, such as virtualization and server optimization, can significantly reduce energy consumption. Virtualization enables you to use fewer servers, thus directly decreasing electricity consumption. Reducing the number of servers in a data center also allows for a smaller power infrastructure. As a result, less energy is consumed by power distribution units, UPS systems, and building transformers.
Collaborative Partnerships
Collaboration between data center operators, utility providers, and technology innovators is essential for driving sustainable practices. Partnerships with renewable energy suppliers, participation in green energy programs, and joint ventures in sustainability projects can amplify the impact of individual efforts.
Overcoming Challenges in the Green Transition
While the need for green data centers is evident, several challenges must be addressed, especially in the US, which hosts around 70% of the world's data centers. Transitioning existing facilities to sustainable practices is more complex than building new, greenfield data centers. This growth in demand for data center services, particularly for GenAI, is driving up power usage and density. According to BCG, data center electricity consumption was 2.5% of the U.S. total in 2022 and is expected to triple to 7.5% by 2030. That’s the equivalent of the electricity used by about 40 million U.S. houses – almost a third of the total homes in the U.S.
Cost Considerations
The initial investment in green technologies can be substantial. However, the long-term savings in operational costs and the potential for government incentives can offset these expenses.
Technological Barriers
Emerging technologies, such as advanced cooling systems, energy storage solutions, building materials, etc., require ongoing research and development, and they have to fuse with existing infrastructure. To be clear, we are thinking of existing data centers vs greenfield. Overcoming technical challenges and ensuring scalability is vital for widespread adoption. Innovations in energy-efficient cooling, renewable energy integration, and advanced energy storage can significantly aid this transition.
Regulatory Support (and Stakeholders' Demand)
Government policies play a crucial role in promoting sustainable practices. Advocating for supportive regulations and incentives can encourage more data centers to adopt green technologies.
Platocom suggests taking this a step further: anchor tenants/enterprise data center customers wield enormous power and could demand sustainable practices when scouting for new data centers.
A Green Sustainable Future Requires Strong Public Private Partnerships (PPP)
As we look towards a greener future, engaging all stakeholders—data center customers, government entities, utility providers, data center operators, and investors—is essential. By fostering a collaborative environment, we can pave the way for a sustainable and resilient data center industry.
