In today’s world, where the climate crisis looms large, data centers have a crucial role to play in decarbonizing their operations. Taking proactive steps now can help organizations stay ahead of global or local policies that may soon require them to implement decarbonization measures. By embracing energy efficiency best practices, data centers can make significant strides towards decarbonization and contribute to the overall protection of our climate. This article explores why decarbonization matters for data centers, the incentives for adopting greener policies, and provides six practical strategies to start the process of data center decarbonization.

Why Decarbonization Matters for Data Centers

Data centers and data transmission networks account for approximately 1% to 1.5% of global electricity use, as reported by the International Energy Agency (IEA). This energy consumption, and the resulting emissions, directly and indirectly impact the climate. The IEA has developed a roadmap, called the Net Zero by 2050 Scenario, which aims to achieve global energy-related carbon neutrality by 2050. This ambitious goal is essential to limit the rise in global temperature to 1.5 degrees Celsius.

Exceeding the 1.5-degree threshold poses significant risks based on observed environmental impacts and historical scientific evidence compiled by the Intergovernmental Panel on Climate Change. These risks include more intense and frequent climate extremes, higher probability of droughts and water availability risks, expansion of flood-prone areas, sea ice-free Arctic summers, ocean acidification, and increased risks of species losses and extinction.

While global commitments and actions are increasing, the world is still falling short of what is necessary to limit the temperature rise. Therefore, data center emissions must be reduced by 50% by 2030 to mitigate the worst effects of climate change.

Incentives to Adopt Greener Data Center Policies

Decarbonization of data centers not only helps protect the climate but also brings several benefits to organizations. These incentives include positive PR, cost savings through improved energy efficiency, and staying ahead of industry regulations.

Positive PR

Customers are increasingly concerned about carbon footprints and expect data center operators to take steps to offset their emissions. By demonstrating a clear commitment to environmental sustainability, data center operators can attract customers who prioritize lower carbon footprints. Additionally, investors are showing interest in companies with strong environmental sustainability plans. Communicating and implementing a clear plan for decarbonization can help attract both customers and investors.

Improve Energy Efficiency to Save on Energy Costs

Investing in renewable energy sources and energy-efficient equipment can help data centers reduce energy costs in the long run. While there may be initial investment barriers, advancements in technology, from hardware to power and cooling equipment, are making energy-efficient options more accessible. Moreover, government subsidies for renewable energy investments can further reduce costs.

Stay One Step Ahead of Industry Regulations

As climate concerns grow, industry regulations are expected to become stricter and more ambitious. By proactively adopting greener policies today, data centers can be well-prepared for future regulations. Investigating decarbonization strategies specific to each data center’s needs is essential to stay ahead in a rapidly evolving landscape.

6 Ways to Start Data Center Decarbonization

Decarbonizing a data center requires a comprehensive and concentrated effort. Here are six practical strategies to initiate the process of data center decarbonization:

1. Partner with Renewable Energy Providers

Transitioning to renewable energy sources is a crucial first step toward decarbonization. Wind and solar power are commonly available alternatives, but data centers should explore other options like geothermal energy or hydroelectricity based on their location. Reducing reliance on fossil fuels is essential to minimize the carbon footprint of data centers.

2. Upgrade the Building

Data center buildings contribute significantly to greenhouse gas emissions, not just through energy consumption but also through construction materials and processes. When constructing new data centers, using materials with lower embodied carbon, such as limestone instead of concrete, can make a substantial difference. Renovating existing structures with locally sourced materials can also help reduce carbon emissions.

3. Utilize Natural Cooling

Data center servers generate significant heat, necessitating extensive cooling systems. Finding the right balance between cooling and heating is essential, as it directly impacts power consumption. Some data centers are experimenting with natural or liquid cooling methods, such as using outside air or seawater, to keep equipment cool. Locating data centers in colder climates can also leverage natural cooling advantages.

4. Reduce Reliance on HVAC Systems

Heating, ventilation, and air conditioning (HVAC) systems are major energy consumers in data centers. Outdated or poorly managed HVAC systems can result in unnecessary energy consumption. Modern control systems that utilize AI models can optimize HVAC usage, thereby reducing energy consumption and carbon emissions.

5. Assess Alternative Options for Backup Power

Many data centers rely on diesel generators for backup power during potential outages. However, battery energy storage is emerging as a superior alternative that eliminates the need for fossil fuels. Assessing and adopting clean backup power options can significantly contribute to data center decarbonization.

6. Review Assets and Their Energy Efficiency

Data center infrastructure management software provides comprehensive transparency into energy consumption for various hardware components. Leveraging this information, administrators can reallocate resources and reconfigure assets for better energy efficiency. Continuously monitoring and optimizing energy consumption can have a substantial impact on data center decarbonization.

A comprehensive transformation towards data center decarbonization requires the implementation of several of these strategies in concert. By adopting these measures, data centers can pave the way for more sustainable infrastructure.

Conclusion

As the world grapples with the climate crisis, data centers have a vital role in decarbonizing their operations. By embracing energy efficiency best practices and investing in renewable energy, data centers can significantly reduce their carbon footprint. Moreover, adopting greener policies brings positive PR, cost savings, and a competitive advantage in a rapidly evolving regulatory landscape. It’s crucial for data centers to take proactive steps towards decarbonization to protect the climate and contribute to global sustainability efforts. With the strategies outlined in this article, data centers can embark on a path towards a more sustainable and environmentally friendly future.
