How Much Electricity Does A Data Center Use?

The data center business will require between 196 and 400 terawatt-hours by 2020. (TWh). This is the equivalent of 1% to 2% of global data center energy use per year. Data centers in the European Union alone will require 104 TWh in 2020, according to another study. With the Data Center industry’s expansion on the rise, energy consumption will continue to rise. These facilities can range in size from modest 100-square-foot data centers to hyper-scale 400,000-square-foot data centers with tens of thousands of cabinets. When you use any internet service, you are connecting to one of the millions of servers in one of the thousands of data centers across the world.

What is the power consumption of a small data center?

Cloud, Data Center Energy, Environment, IT Energy, published(updated:)

Cloud, Data Center Energy, Environment, and IT Energy are some of the terms used to describe how energy is used in data centers.

In 2020, data centers are expected to consume between 196 and 400 terawatt hours (TWh) globally (Masanet et al, 2020) (Hintemann, 2020). As a result, data centers account for 1-2 percent of global electricity usage.

However, this figure could be far higher. According to one analysis, global data center energy consumption was 270 TWh in 2012. (Van Heddeghem et al, 2014). Another study projects that European Union data centers will consume 104 TWh in 2020, resulting in a global total of 200 TWh on the low end (Avgerinou, Bertoldi & Castellazzi L, 2017).

How much power do servers consume?

Some racks can now reach 20kW, depending on the data center, although the average is closer to 7kW. As the demand for data centers has grown and continues to grow, cooling and ventilation has become a significant barrier for high-density server functioning.

In the United States, how much energy do data centers consume?

The “United States Data Center Energy Usage Report,” published in June 2016 and supported by the U.S. Department of Energy’s Federal Energy Management Program, looked at data center power usage going back to 2000, presented analyses of how it has increased, and forecasted power usage in the early part of this decade.

Data centers in the United States utilized an estimated 70 billion kWh in 2014, accounting for around 1.8 percent of overall electricity consumption in the country. According to the current analysis, data center power consumption increased by about 4% from 2010 to 2014, a significant change from the predicted 24 percent increase from 2005 to 2010 and nearly 90% increase from 2000 to 2005. Energy consumption is predicted to increase somewhat in the near future, rising 4% from 2014 to 2020, the same rate as the previous five years. According to current forecasts, data centers in the United States will require around 73 billion kWh in 2020.

Statista Inc. presented a more recent research of data center energy consumption patterns on September 30, 2021. Nane Snnichsen’s analysis, “Global Data Centers Energy Demand by Type 2015-2021,” found the following:

Traditional data centers’ energy use has reduced globally, from over 97.6 terawatt-hours in 2015 to roughly 50 terawatt-hours in 2019, with an estimate that this figure will reach nearly 33 terawatt-hours by 2021. Hyperscale data centers, on the other hand, have doubled their energy use in the same time span.

In addition, the research forecasted data center utilization in three categories: traditional data centers, non-hyperscale cloud data centers, and hyperscale cloud data centers, year by year.

Traditional data center operators are usually focused on increasing output and performance while overlooking the power implications. The need for more computing capacity in large corporations frequently resulted in the construction of additional data centers, which resulted in a huge increase in energy usage. This pattern may be seen in the earlier years of the table above.

The availability of considerable computer capacity without the need for physical space, on the other hand, has encouraged the trend of closing legacy data centers and transferring activities to the cloud.

By keeping their energy consumption constant, non-hyperscale cloud data centers demonstrate their utilization of energy-efficient equipment and environmental systems. For the same reasons, large, hyperscale cloud data centers have continuously grown their energy use and effectively managed it.

When the columns in the table above are combined together, the overall energy demand in 2015 is 190.7 terawatt-hours, while the demand projection for 2021 is 190.8 TWh. This demonstrates how energy-saving equipment and green data center operations keep energy expenses in check.

Why do data centers consume so much energy?

In a typical data center, there are many different types of equipment, almost all of which require electricity. The many types of energy-consuming devices, as well as overhead lighting, found in a typical data center are depicted in this diagram.

Servers and network communications equipment that are older spend more energy than newer, more energy-efficient ones. Each of the above components can be replaced with more energy-efficient solutions.

How is data center energy consumption being addressed?

Organizations engage in a variety of actions to increase data center energy efficiency and minimize energy demand on a regular basis. Green data centers are the umbrella word for all of these activities. Green data center activities, with a focus on cloud data centers, include the following:

  • Efficiency in terms of energy use. Using environmentally friendly power sources, reducing carbon footprints, contracting with power-generation utilities to supply green energy, regularly measuring power usage effectiveness, and having documented plans and time frames to become carbon-negative and remove all carbon from the environment are all examples of energy-efficiency improvements used by cloud vendors.
  • Renewable energy is used. Wind and solar energy are two of the most common renewable energy sources employed by cloud providers. Renewable energy sources can be owned and managed entirely by the cloud vendor, or obtained through contracts with renewable energy providers.
  • Buildings for data centers that are environmentally beneficial. Existing and future cloud data center facilities are typically designed and built in accordance with current design criteria for energy-efficient building construction.
  • Site selection for data centers. Floods, earthquakes, hurricanes, and other natural disasters should all be considered while choosing a location. To maximize energy efficiency, cloud vendors have access to low-cost energy and dependable telecommunications infrastructure.
  • Management of the HVAC system. As part of a typical HVAC suite of systems, energy-efficient cooling systems are carefully regulated for energy consumption. To maximize operational conditions, temperature, humidity, and heat load a consequence of energy usage are monitored and adjusted. The local climate, as well as compliance with local, state, and federal rules, are other factors to consider.
  • Fire and water damage protection. Water detection sensors are strategically placed throughout data centers to alert operators to any water breaches or flooding. The data center, as well as its adjoining work areas, conference rooms, food service areas, and utility rooms, are equipped with fire and smoke detection devices and suppression systems, such as FM-200 discharge and wet-pipe and dry-pipe water systems.
  • Energy efficiency in infrastructure. Utility firms generally provide commercial electricity and telecommunications to cloud data centers. Cloud vendors frequently have standards and procedures in place to evaluate utility providers’ eco-friendliness.

Data center power consumption going forward

In the future years, data center power consumption will continue to rise. This development is being spurred in part by the growing popularity of cloud data centers, which are currently among the greatest energy consumers. For data centers that use technology like energy-efficient HVAC systems, equipment racks with cooling systems, and energy-efficient doors and windows, managing energy consumption will be a key ongoing job.

The data center industry in the United States isn’t the only one advocating for green data centers. The Climate Neutral Data Centre Pact, for example, is a major movement that intends to make data centers in Europe climate-neutral by 2030. The deal also backs the European Green Deal, which aims to achieve climate neutrality in Europe by 2050.

What is the energy consumption of a hyperscale data center?

Most data centers’ main operational expense is power, so lowering power costs is frequently a top priority. Power usage in hyperscale data centers is on another level, with an average of 20-50 megawatts (MW) per data center and 10-25 kilowatts (KW) each rack. Globally, data centers utilize about 3% of total energy output, with hyperscale data centers accounting for 20% of global data center electricity usage and expected to expand to 50% by 2020. Microsoft’s 700,000 sq. ft. data center in Chicago, Illinois, is one of the world’s largest data centers, capable of consuming 198MW of power. To put that into perspective, 1MW of electricity is enough to power an average of 750 households in the United States; hypothetically, this data center could draw enough power to power 150,000 homes. Hyperscale operators are sometimes buying every single kilowatt of power generated from new renewable energy sources to meet their data center’s power needs. While hyperscale data centers consume a lot of power, they are significantly more efficient than scaling networks and servers on-site. According to the Lawrence Berkeley National Laboratory, relocating 80 percent of servers in the United States to efficient hyperscale facilities will result in a 25 percent reduction in energy use. While many people believe that massive hyperscale data centers use a lot of electricity, this is not the case.

What sources of energy are used to power data centers?

Even the most complex and powerful network is nothing more than a pile of metal junk without power. You could be wasting money no matter how smart your setup is if it isn’t getting and using electricity efficiently. When it comes to data center electricity, there are a few key concepts to understand.

When it comes to powering your data center or any other device that utilizes energy, you have two alternatives. Alternating current (AC) power When you plug in a device, appliance, or equipment, you’re thinking of current power. On-demand currents of 120 or 240 volts Simply put your device into an available outlet and you’re good to go. The “alternating” aspect of this type of electricity comes from the manner it’s delivered; it can shift direction numerous times in a minute to improve performance and efficiency.

Your laptop, phone, and other gadgets that may be connected to an AC outlet to charge and then run off of the battery rely on DC power, or Direct Current power. Direct current has only one direction of flow and is more reliable than alternating current, making it a good approach to avoid. While alternating current power is used by the majority of colocation data centers, an increasing number of companies are using DC power and a combination of the two to improve energy efficiency and reduce downtime.

The ratio of power available to a data center vs. the power consumed by IT equipment is known as power usage effectiveness, or PUE. PUE (Power Usage Effectiveness) is a measure of efficiency that can disclose how much power your servers consume and how much is consumed by non-server/non-IT activity. A high PUE indicates that you could be using too much power and could be running more efficiently than you are. A low PUE indicates that you are operating at peak efficiency and have little waste.

Divide the total energy consumed by your complete facility by the energy consumed by your IT equipment to get your center’s PUE. Your PUE is the result of this calculation, and it should be as near to 1 as feasible. Why is it so low? Lower ratios indicate that you are using the majority of your energy to getting the task done rather than powering the office, lights, and other support equipment.

What causes data centers to consume so much energy?

“During the 2020 lockdown, there was a 9% increase in residential carbon emissions, and we’ve witnessed a drop-off in home retrofitting, which started in 2019 and ended in 2020.” Retrofitting homes requires a paradigm shift, and it must be prioritized as part of the capital plan.

Mr Naughten’s remarks echoed Labour TD Duncan Smith’s reservations, which he expressed around the same time as Ms Boylan’s misgivings in December.

Mr Smith stated that large business, not the regular citizen, would be the big beneficiaries if they collaborated.

“The renewable energy that is coming online will not be held by the government.” Because it will be privatized, we will go from big oil to big wind. I’m hoping we can come up with another phrase. This is our destination.

“The government needs to tell us how much of the renewable energy coming online will be siphoned off for other multinational corporations like data centers that are entering into prepaid contracts with companies that own windfarms to siphon off up to 15%, 20%, or 25% of the energy created to power data centers, which are huge carbon emitters and poor job creators.”

“There is a system here that will only grow in size, and it will be awful for workers, the economy, and Irish taxpayers because we will continue to pay enormous penalties to countries that are doing things far better than we are.”

Eamon Ryan, the Environment Minister, has sought to appease critics by stating that the government will consider all interests.

“We’ll probably utilize a mix of ways, but one thing we’ll make sure of is that demand, whether from data centers or other large energy consumers, is planned in a way that lowers costs, reduces emissions, and provides a truly sustainable system.”

“This could mean placing data centers near power sources or limiting access to select places where the grid can’t handle the extra load.” It will not, however, say no to data centers because they are necessary for the overall economy.

Why have data centers become such a big deal in Ireland in the last few years? According to Professor Brian Norton of the Tyndall, it’s primarily geography and chance.

“There are a variety of reasons why data centers are located close to us. They have control over a wide range of dimensions. One is that Ireland has a good climate for data centers since it has a large amount of coolant. Because they have a higher cooling burden, you don’t want to install them in hot areas. Ireland is a good example of a good location.

“You also want data centers close to network hubs, and Ireland has lines running across the Atlantic as well as ones connecting to the UK and Europe.” When you consider the physical geography of the Earth, you’ll see that there are particular spots where important cables land and natural nodes.

“Because of the cables traveling beneath the sea that turn up in certain spots, you expect to see large data centres on the shores of the United States and Europe.” There are natural geographies and climates of the globe that you want to put things in, he continued, and they are physical, geographical, and climatic reasons.

According to Prof Norton, it is a coincidence of facts such as geography and climate.

“You don’t want them in warmer regions because they merely add to the cooling burden, and it has to do with privacy legislation and oversight of what is done with your data.” It’s a mash-up of all of those facts.

“Another reason is the data’s purity and security, as well as, more crucially, the data’s operations.” In Europe, for example, there are real worries about privacy and the rights that people enjoy.

“Similar privacy rules do not exist in the United States, nor do they exist in China.” Outside of the jurisdiction, your capacity to take legal action if you believe your data has been exploited is plainly limited. People want things to be stored locally for these reasons.

While data centers consume and generate a lot of energy and waste, he believes that the ever-growing field of renewable solutions will help mitigate the problem, but that it will take vision and invention.

“In a data center, the majority of the energy is normally utilized for the IT equipment, the servers that are in the data centers, and around half of it is used for cooling systems in some fashion around those, that is how the energy ends up being used within.” All of this is eventually discharged as very low-grade heat. It’s essentially lukewarm air.

How much does it cost to run a server 24 hours a day, seven days a week?

Depending on how you scale and the game you’re playing, renting a server might cost anywhere from $5 to $150 per month.

Running the server, on the other hand, is a different affair. You’ll save a lot of money if you set up a server at your home or company. You only have to pay for electricity rather than a hosting firm.

A server can consume between 500 and 1,200 watts per hour on average. If you multiply 850 watts per hour by 24 hours in a day, you get 20,400 watts per day, or 20.4 kilowatts per day (kWh). So, for a year, it would cost $731.94 to run the game server on your own.

What is the global energy consumption of data centers?

Data transmission networks consumed 260-340 TWh globally in 20203, accounting for 1.11.4 percent of worldwide electricity consumption.

Data transmission network technologies are also fast improving in efficiency: in industrialized nations, fixed-line network energy intensity has halved every two years since 2000, while mobile-access network energy efficiency has increased by 1030 percent annually in recent years.

Data from a number of global network operators shows how advancements in energy efficiency have helped to divorce data traffic from energy use. Sprint, for example, cut its network energy intensity by more than 80% between 2014 and 2019 while maintaining the same overall network energy consumption, and data traffic across Telefnica’s networks rose fivefold between 2015 and 2020 while electricity consumption declined 2%. (this includes 45 percent traffic growth in 2020, with electricity use remaining at the 2019 level).

What is the electricity consumption of a data center per square foot?

Many data center operators are confronting increased workload requirements from big data, machine learning, and similar technologies as they try to squeeze every ounce of efficiency out of their facilities.

As a result, many data center operators are forcing server racks to work harder by raising the power density within each rack. According to numerous operators, the power density inside each rack cabinet, as well as across the data center as a whole, has increased dramatically in recent years.

Workloads in data centers have expanded drastically “According to Craig Broadbent, VP of customer solutions and services at Virtual Power Systems, a data center software vendor, demand for power density at the rack level has also surged.

Previously, data center operators “to address the increase in IT requirements, data centers have chosen to throw additional low-density racks at the problem, resulting in rack sprawl, but that’s changing as data centers focus on hyper-scale workloads while restricting the amount of space they use, he added.

A server rack’s power density was normally in the 3kW to 5kW range by the end of the last decade. Many operators claim that number has gradually increased, yet no one knows what the current range is. Some operators claim that a typical rack’s power density is now between 5 and 13 kW, while others claim that some racks can consume up to 40 kW.

According to Mike Kilkeary, associate principal engineer at Southland Engineering, the normal power density in a data hall has gone from 150 watts per square foot to 250 or 300 watts per square foot, with some providers reaching up to 400 watts per square foot.
