While green data centers can only afford IT-giants| 04.07.2020
The larger a technology company, the stronger its data center or data center, respectively, consumed more electricity, which is one of the most powerful articles
consumption. However, we need to solve the problem of excess heat generated by the servers. For each watt consumed in the data center for its intended purpose, there are 2.5 watt for cooling. British
the journal Nature provides evidence that the annual demand for data centers is approximately 200 TWh, a value comparable to the national energy consumption in some countries. The energy
get data centers are not always produced from clean sources. China, ranked second in market data centers, more than 70% of electricity for the needs of the data centers that receives heat
power plants using coal. Every year the number of technology companies whose business relies on data centers increases.
The problem became so serious that there is a sustainable phrase “green data centers”. Ten years ago, difficulties with cooling was solved along the way, but now the DPC already design
combining the features of the technology and the conservation of the environment. The symbiosis of digital technologies and the protection of the environment is developing in two directions. One of them implies construction of
data-centers using recycled recyclable materials and environmentally friendly construction materials. The second involves the creation of energy efficient engineering systems.
The choice of the construction site of the data center indicates the intentions of the company. The main emphasis in the design of Verne Global was made on the condition that his consumption will be ensured
geothermal energy. Therefore, and built a data center near the geyser. In Frankfurt in the project data center, Citigroup is the possibility to use as a refrigerant rainwater.
Main energy consumption of data centers is reduced to two areas: the IT load and cooling systems. Freon air conditioning and chiller-fan coil units replaced systems with direct or indirect
free-cooling system. Data-centers of Amazon, Google, and Facebook use direct free-cooling technology server. This means that the outdoor air before entering the cooling pre-cleaned.
Indirect free cooling implies a closed cooling cycle.
Microsoft pays attention to researches in various fields. The company is experimenting, in particular, and cooling systems. Is searching for alternatives to the free-cooling system. One such attempt is possible
consider placing waterproof DPC in the ocean. The inaccessibility of the server in case of failure of its components will void the benefits of natural cooling.
Microsoft and other IT giants promise to reduce your carbon footprint. In particular, Microsoft announced the phased elimination of consequences of emissions of carbon dioxide. By 2030, the company
going to achieve carbon-neutral status. Ideally, the European data centres by the year 2030 will be carbon-neutral. One of the Danish companies have designed and launched the system
heat transfer from a data center in the urban heating network. The heat produced by the data-center is used 70%. The Danish authorities plan to 2030 to reduce emissions of carbon dioxide. Technology
heat transfer is partially delaying the implementation of this quota. In Finland, England and other countries do as well: the excess heat of some data centers that are used to heat homes.
Data center of IBM in Switzerland part of their gives excessive heat to heat a nearby swimming pool. Such examples are enough, their number will grow.
For data centers important to use solar and wind energy. An example is the data center Internet company in Illinois, providing power for its servers by the wind turbine.
Practice shows that the development of green data centers in time. Yet fully transition to clean energy is possible only for data centers of major companies. They are today more
bear environmental responsibility. Changes in energy efficiency policy is inevitable. Risks associated with changes frighten many. But with great concern we must treat competition
where a significant role will be played by energy costs and compliance with environmental regulations.
