In our increasingly digital world, data centers silently hum with activity, powering the services we rely on daily. The streaming services that keep us entertained, the social media platforms that keep us connected, the banking services that safe keep our hard-earned money, the investment platforms like brokerages that keep our assets liquid, the eCommerce apps that deliver almost everything to our doorstep, the ride hailing apps that help us with our daily commutes, the food delivery apps that keep us well fed, the map apps that help us navigate around the city, the online travel portals that take us to our next vacations, and the list goes on. Yet, behind the sleek exteriors of these digital services lies a significant environmental impact. Let’s zoom in on the data centers that these digital services reside in — the unsung giants of energy consumption — and explore their climate implications.
- Global Data Center Emissions:
- Data centers, those sprawling warehouses of servers and networking equipment, contribute around 2-4% of global greenhouse gas emissions.
- However, this figure varies by region. In Singapore, where data centers play a pivotal role in supporting the digital economy, their impact is even more pronounced—accounting for approximately 7% of the nation’s total emissions.
- Low Utilization: A Hidden Inefficiency:
- Here’s the paradox: Despite their critical role, data centers often operate with surprisingly low average utilization levels.
- The average rate of server utilization hovers at a mere 12-18% of capacity globally. Imagine a vast warehouse where most of the racks remain underutilized, like empty seats in a theater during a blockbuster movie.
- This underutilization leads to inefficiencies. Servers draw power even when they’re not fully engaged, and cooling systems work harder than necessary.
- Power Usage Effectiveness (PUE): A Key Metric:
- PUE (Power Usage Effectiveness) is our spotlight metric. It measures data center energy efficiency by dividing total facility power by the power used specifically by IT equipment (servers, storage, and networking gear).
- A lower PUE indicates that a higher percentage of a data center’s energy consumption is being put to productive use, rather than being expended on cooling systems, power supply inefficiencies, and underutilized IT equipment.
- By striving for a PUE close to 1, data centers can optimize their energy usage, minimizing waste and reducing their carbon footprint.
Navigating a Greener Future
- Collective Responsibility:
- Globally, countries have committed to reducing emissions through Net Zero targets. Governments are enacting laws and policies to drive change across the economies.
- Singapore, for instance, mandates climate-related disclosures by listed companies starting in FY2025. That means all listed companies will have to calculate their carbon footprint and disclose it as part of regulatory filings. This regulatory push is expected and intended to create a ripple through supply chains, nudging businesses toward carbon-conscious decisions.
- Businesses and Sustainability:
- Reporting fosters awareness and transparency. It’s a crucial step toward reducing emissions.
- In Singapore, where technology underpins various sectors — from finance, manufacturing, logistics to e-commerce — companies must embrace sustainable practices.
- Driving Transparency, Empowering Digital Service Providers
- At Karbonless, we’re on a mission to help digital service providers and all users of data centers understand the climate impact of their IT infrastructure. We’ve designed Karbonless to be an easy-to-use platform that empowers every stakeholder to make carbon conscious and carbon responsible choices when it comes to the use of IT infrastructure.
- The granular views of sources of carbon emissions drive transparency, accountability and action. This is complemented by decarbonAIzer – our AI-based automated recommendation engine that helps you identify opportunities of carbon optimization.
Remember, every byte of data processed, every virtual meeting held, every cloud service accessed and every idle server in your data center has an environmental cost. As we digitize, let’s also prioritize efficiency and collective action for a greener IT landscape.
