Green Data Center

Top Green Data Center Facilities

Many companies aim to have efficient, green data centers, and here is a list of the top performers. There are a lot of renewable resources such as solar, wind, geothermal, and hydroelectricity that help to power these data centers. When coupled with top-of-the-line electrical equipment and innovative cooling solutions, the latest generation of data centers is among the planet's greenest facilities.
To rate the facilities a number of factors have been taken into account. Power usage effectiveness (PUE), despite it's ability to be manipulated, is one way to get a basic understanding of the energy use for comparison. Certifications, such as the U.S. Green Building Council's Leadership in Energy and Environmental Design (LEED) and EnergyStar rating, also play a role in how environmentally friendly the facility was constructed and operating. Other inputs have been measured as well, such as Greenpeace's Click Clean reports, to understand the end-to-end energy consumption.
It should also be noted that some of the most efficient data centers are not necessarily the most robust in terms of reliability. There are redundant components, equipment, and systems that are streamlined for better performance holistically. Additionally, other factors are not considered, such as connectivity to existing networks or geographic safety of the region.

Given the complexity and need for reliable data centers, reach out and connect with experts in the industry. The quality of service will lead to better improvements that are faster than try-fail or over simplification.


A green data center is a source for the management, storage, and distribution of data during the electrical, mechanical, lighting, and computer systems that are developed to offer the utmost energy efficiency and reduced environmental impact. The structure and function of a green data center mainly consist of advanced technologies and strategies. Green data center possesses the same features and attributes as a usual data center, although they consume less energy and space. Green data centers often help in certifying diminished costs and reduce an organizations carbon footprint due to the implementation of efficient power systems, routers, servers, cooling, lighting, and controls.


It should be noted that there are a lot of different types of DCs and different metrics (beyond PUE) are needed for comparison.
There are a lot of different types of facilities and different metrics (beyond PUE) that are needed for comparison. Each data center has a way to be optimized in its own way.

Depending on the type, a data center typically uses many megawatts (MW) of power, with some well over 100 MW. A residential home can use about 10,000 kW-hours per year; for every 1 MW of a data center, it uses about 8,760,000 kW-hours per year - about 876 homes-worth.


Depending on the end user, they can range from an over-sized closet to large campuses with many buildings over 300,000 square feet each.
