Energy-efficient Data Centers: Strategies For Reducing Operating Costs In The Desert – Saving energy in the office may not be the hot topic of conversation around the water cooler, but it is one of the best ways to reduce operating costs. These simple, cost-effective and energy-saving measures will help you increase your profits.

Get some sleep. Computers, printers and copiers are often on all day, but see usage. You can save a lot of power by setting the sleep mode to low power.

Energy-efficient Data Centers: Strategies For Reducing Operating Costs In The Desert

Switch to laptops or tablets. When upgrading computers, consider purchasing laptop or tablet models. Today’s laptops can handle most office tasks while using significantly less power.

Innovations In Data Center Power Software Defined Power And Energy Optimization

Share the printer. Do you have a printer in every office? you’re wasting energy. Network printers to be shared by multiple employees. This saves energy and reduces paper waste.

Connect smarter. Many electronic devices draw power 24 hours a day, even when they are not in use. Advanced extension cords automatically turn off devices when not in use.

Make it less personal. Personal appliances are expensive and difficult to control. Limit usage by maintaining a comfortable temperature and making appliances accessible in your central break room.

Buy ENERGY STAR®. ENERGY STAR certified office equipment uses less energy than standard models while providing the same level of performance.

Greening The Or

Install occupancy sensors. Stop wasting energy lighting up spaces that are often empty – like restrooms and conference rooms. Occupancy and occupancy sensors automatically turn off the lights when the room is empty.

Lighting upgrade. Replace older T12 fluorescent lamps with replacement LED tubes or LED fixtures. They offer higher efficiency, better light quality and easy compatibility with controls.

Don’t stay in the office. View your entire device. You will likely find many ways to reduce energy waste and increase efficiency.

Data Center Optimization

Information and communication technologies (ICT) are increasingly penetrating our daily lives, and we are increasingly entrusting our data to the cloud. Events such as the COVID-19 pandemic put an extraordinary strain on ICT. This includes the increasing implementation and use of data centers, which increases energy consumption and environmental impact. The aim of this work is to summarize the current situation in data centers in terms of environmental impact and opportunities for improvement. First, we introduce the topic and present the estimated energy consumption and emissions. We then review proposed strategies for energy efficiency and energy conservation in data centers. Energy consumption refers to energy distribution, ICT and non-ICT devices (e.g. existing and expected strategies and initiatives in these sectors are identified. Key elements include innovative cooling techniques, natural resources, automation, low-energy electronics and devices with extended thermal limits. They are research perspectives are identified and opportunities for improvement are estimated Finally, we present an overview of existing metrics, the regulatory framework and relevant authorities.

The digital economy is expanding and with it the demand for information and communication technology (ICT), which drives the data center industry. Compared to the recent “Age of Computing”, the current era is considered the “Age of Data” [1]. The recent massive expansion of ICT is driven by fifth-generation (5G) mobile networks, modern computing paradigms, the Internet of Things (IoT) [2, 3], cryptocurrencies, blockchain [4], big data science, artificial intelligence (AI ) and extraordinary events, such as the ongoing COVID-19 pandemic [5, 6]. Key estimates of Cisco’s digital development in 2018-2023 are shown in Table 1 [7].

The fifth generation mobile network, known as 5G, is being implemented to meet the growing demand for services [8]. The related energy demand is the subject of research [9, 10].

Cryptocurrencies (Bitcoin being the first and most famous) are mediums of exchange that are digital, encrypted and distributed. They are not issued by a central authority, but rather are based on a distributed ledger, typically a blockchain. Mining is the release of new units of cryptocurrency [11, 12]. Energy and environmental costs of cryptocurrency mining are an emerging issue [13, 14, 15, 16, 17]. The estimated energy consumption associated with Bitcoin is shown in Figure 1. Sustainable alternatives are under investigation [18].

Blockchain is an open-source distributed database based on state-of-the-art cryptography through a distributed ledger [19]. The first application of blockchains was to support Bitcoin transactions; today, they are considered disruptive in many applications [20, 21], including climate change [22], energy [23], and health [24]. A recent application of blockchains is in the field of smart mobility, supporting the Internet of Vehicles [25]. The energy and environmental impact of blockchains is being investigated [17, 26]. Other driving forces are modern computing paradigms – cloud computing, edge computing, fog computing and IoT [3].

The COVID-19 pandemic has changed the use of ICT. In March 2020, Microsoft Teams usage increased by 775% [27] and Facebook group calls increased tenfold in Italy [28]; Zoom has exceeded 200 million daily participants [29]. Changes in the use of social media after COVID-19 are addressed by, for example, J.P. Morgan [30]; Amazon profited significantly [31]. This can also lead to beneficial outcomes: Ong et al. [32, 33] estimate the energy and CO impact of videoconferencing

Information traders (e.g. Google/Alphabet, Amazon, Apple, Facebook, Microsoft) are among the top companies by market capitalization [34, 35]. ICT electricity demand is expected to accelerate to 8% ÷ 21% (based on scenario) of total electricity demand in 2020–2030 [36]. The energy consumption of data centers can reach hundreds of megawatts [37]. Examples of top data centers by performance are shown in Table 2.

Data centers use ICT equipment (servers, storage units and network equipment) that are powered by electricity. ICT operations require non-ICT facilities or data center physical infrastructure (DCPI), e.g. cooling to remove heat from ICT, lighting (Figure 2).

Doe Data Center Energy Efficiency Program And Tool Strategy

The highest energy consumption items are cooling and servers, each estimated at 43%, followed by storage units and network devices (11% and 3%, respectively) [39]. Other estimates are roughly 52% ICT, 38% cooling system and 10% other equipment [40].

Energy flows in a typical data center are shown in Figure 3. Estimates of electricity use 2010–2030 for ICT and data centers are shown in Figure 4. Global greenhouse gas (GHG) emissions from ICT are shown in Figure 5.

For these reasons, the energy and environmental sustainability of data centers is a priority in the ICT industry. European strategies promote data centers to be carbon neutral by 2030 [43].

The main actions related to the energy consumption and operational carbon of data centers are high-performance computing resources (software); energy saving of computer rooms (hardware); low consumption servers (hardware); and renewable energy applications (hardware) [47] (Figure 6). In this work, we focus on energy conservation strategies at the physical level (ICT and DCPI) as shown in Figure 7 – energy conservation at the software level is out of the scope.

Grid Energy Storage

Electrical power plays a key role in the proper and efficient operation of a data center. Data center load can be classified into two main levels according to the type of service required. DCPI requires priority service via Emergency Generating Sets (EGS) – given the inertia of the system, downtime in the order of seconds is tolerable. ICT and critical equipment require a vital service with strict continuity of supply through Uninterruptible Power Supply (UPS) systems – they are vulnerable to even very short (millisecond) voltage dips. The ISO 8528-1:2018 standard defines the use, evaluation and performance of EGS [49]. The ratings are shown in Table 3.
