Introduction
The need for online services is on the boom, and so is the stress on our environment. Data centers consume immense power, that are also a good heat generator. They are contributing increasingly to global emissions. This fact has necessitated an immediate demand for improved methodology.
A green data center is the answer. It decreases the energy usage and the environmental harm, but provides credible IT services. This blog describes the term: What is green data center? Understand the functionality, its advantages, difficulties and the direction that the Indian market is taking.
What is a Green Data Center?
A green data center is a datacenter that holds and handles data without sacrificing the essence of energy savings and sustainability. It utilizes renewable energy sources and energy-efficient hardware. Cooling systems save on electricity and water. Building constructions are usually done using materials that are not very harmful to the environment.
The objective is to ensure the reliability of IT operations with less pressure on the environment.
Green data centers are centers that substitute high-energy equipment with low-energy-consuming hardware. They also plan the physical structure in a manner that enhances air circulation and lessens heat. Operators make use of software and monitoring tools to optimize performance. Sustainability levels are commonly proven with the help of such certifications as ISO 50001 on energy management and LEED on building design.
Simply put green data center solutions aim at providing the same performance at a lower environmental degradation.
Global Green Data Center Market Insights:
In 2023 and 2024, the green data center market size is estimated to be approximately 70.58 billion USD and 81.75 billion USD, respectively. By 2032, it is projected to hit 307.52 billion USD with a CAGR of 18.
Measures to Quantify Sustainability in Data Centers
Discussion on ‘what is green data center’ cannot be complete without metrics. These are the figures which indicate the efficacy of a facility. Claims to be green are just marketing without them. They are also used to compare performance and monitor performance towards sustainability.
Power Usage Effectiveness (PUE)
PUE is the most used measure. It is determined by dividing all facility energy by the IT equipment energy. The closer a PUE is to 1.0, the greater the efficiency. The global data center PUE average is 1.55. Some advanced facilities are indicating a low PUE of as low as 1.1.
Data Centre Infrastructure Efficiency (DCiE)
DCiE is the inverse of PUE. It indicates the proportion of overall power which is actually used by IT equipment. Greater DCiE is an indicator of superior performance.
Effectiveness of Carbon Usage (CUE)
CUE is used to quantify the level of IT energy emitted as carbon. It reveals the cleanliness of the energy source. Plants that operate on coal power will be more CUE than plants that operate on solar energy and wind power.
Water Usage Effectiveness (WUE)
WUE displays the liters of water per kilowatt of the IT equipment’s power used to cool. Water-based cooling is commonly used in data centres in hot climates, and this number is therefore raised. In areas where there is water stress, high WUE may be an issue.
Green Building Certifications.
Besides the technical measures, certifications such as LEED (Leadership in Energy and Environmental Design) and ISO 50001 are used to demonstrate that the facility adheres to high efficiency requirements. The certifications enhance the ease with which the users and investors can trust green data center solutions.
Features of a Green Data Center
