In the past few years, there has been an incredible surge in data center construction around the world. Companies like Microsoft, Facebook, and Amazon are spending huge amounts of capital to build them in places like Singapore, Taiwan, and Tokyo. The reason for this unprecedented growth is the expanding global need for both business and personal connections.
However, the amount of energy used to operate data centers is extreme. According to the U.S. Department of Energy, data centers are “the energy hogs of the computing world,” and a study released in June 2016 found that “US data centers consumed about 70 billion kilowatt-hours of electricity in 2014… representing 2 percent of the country’s total energy consumption… equivalent to the amount consumed by about 6.4 million average American homes that year.”
This type of energy consumption places huge drains on global infrastructures. Therefore, a push to develop energy-efficient data centers is at the forefront of IT concerns.
The Definition of a Green Data Center
Green data centers are those that are designed for maximum performance and efficiency, using a minimal amount of resources. Basically, that means that all of the hardware (the mechanical, electrical, and computing equipment) is arranged and operated in a way that reduces the environmental impact of the data center. There are a number of energy-saving strategies used to reduce consumption in data centers, including:
- Low emission building materials
- Water reuse and recycling systems (much water is required for cooling purposes in these industrial-scale facilities)
- Alternative energy technologies (new cooling systems, photovoltaics, and innovative heating units)
Reducing energy consumption at the data center does more than help our environment; it offers OPEX reductions for the owners.
Current Data Center Condition
Over the last decade, there has been an incredible surge in the need for industrial facilities housing large amounts of server and other hardware equipment. Designed specifically for the needs of electronics, these structures require massive amounts of environmental and security controls. However, their proximity to users does determine certain latency issues. Therefore, the abundance of affordable smart devices and increasing ranges of connectivity, combined with a plethora of new “as-a-service” offerings, has generated high demand for more data centers around the world.
The fact that cloud connectivity presents a number of cost-saving and performance improvement strategies for enterprises has also contributed to data center expansion, and even the number of providers who are “born in the cloud.” According to Gartner, IT is projected to shell out nearly $1 trillion over the next five years transitioning to cloud computing services. That type of infrastructure will depend on more data centers for support.
Data center development has increased, and likewise the energy required for operation. The good news is that the global commitment for developing more green facilities is strong. By investing in conservation and reuse equipment, providers will be able to transfer the savings on to the end user. In addition, although the initial capital expenditure is higher than traditional construction, a green data center delivers measurable ROI and long-term reductions in operating costs.
