From streaming movies or games and sharing photos on Instagram to the growing use of \u2018smart\u2019 devices and growth in artificial intelligence (AI) technologies, the amount of data being processed is escalating. As a result, energy consumption of data centres in the European Union (EU) is expected to rise from 2.7% of electricity demand in 2018 to 3.2% by 2030<\/a>.<\/p>\n

 <\/p>\n

Cooling data centres can take up to 40% of their total energy consumption. \u2018Cooling a data centre is a big issue,\u2019 said Xudong Zhao, professor of engineering at the UK\u2019s University of Hull. \u2018You\u2019ve got a lot of heat generated from the data centre that needs to be removed \u2026 continuously,\u2019 he said.<\/p>\n

\u201cYou\u2019ve got a lot of heat generated from the data centre that needs to be removed \u2026 continuously.\u201d – Xudong Zhao, professor of engineering at the UK\u2019s University of Hull<\/p><\/blockquote>\n

 <\/p>\n

While building data centres in cold environments like the Arctic Circle<\/a> or the ocean<\/a> may be one solution, energy-efficient technologies are also needed to cool thousands of centres located in warmer climates.<\/p>\n

 <\/p>\n

Prof. Zhao is coordinator of a project called DEW-COOL-4-CDC<\/a> that has developed an air conditioning system that uses between 60% and 90% less<\/a> electricity than a standard one. The technology works by extracting hot dry air generated by the data centre and passing it over water that then evaporates in the heat, leaving the air cooler.<\/p>\n

 <\/p>\n

Traditional air cooling systems use condensers, compressors, and evaporators, all of which are very energy intensive, explains Prof. Zhao. The technology is at the pilot stage, but once it gets to market and is produced on a large scale, it should cost about the same as traditional air conditioning systems, he says.<\/p>\n

 <\/p>\n

Share the load<\/strong><\/p>\n

\u00a0<\/strong><\/p>\n

Another way to reduce electricity consumption is to closely monitor the way servers in data centres are working, says \u00c7a\u011fatay Yilmaz, coordinator of ECO-Qube<\/a>, another project developing energy-efficient cooling solutions for data centres. For example, if just two servers in a roomful of servers are doing all the work, spreading the load between them all will reduce the amount of cooling needed, says Yilmaz.<\/p>\n

\"\"<\/a><\/p>\n

Small data centres are easy to monitor and manage in this way \u2013 and they have the potential to reduce energy consumption by about 20%, says Yilmaz, who is innovation manager of Lande Rack Cabinet, a company based in Istanbul.<\/p>\n

 <\/p>\n

Another option ECO-Qube is researching is to integrate data centres in a residential or office building. That way, excess heat from the servers can be used in the building and its water supplies. \u2018You can collect the waste heat [from] the servers and use it as an additional heating system for your building, for your showers, for generating electricity,\u2019 said Yilmaz.<\/p>\n

The project is trialling this in a research and innovation building<\/a> in Switzerland.<\/p>\n

 <\/p>\n

In the meantime, the spiralling volume of mobile data and development of AI technologies is increasing demand<\/a> for data centres.<\/p>\n

 <\/p>\n

Widespread lockdowns and increased home-based working since the start of the Covid-19 pandemic have also boosted demand for digital infrastructure, says JLL, an international real estate services firm that works with data centres<\/a>. Demand for data centres in Europe\u2019s major cities is expected to rise by a third<\/a> in 2021, JLL said in March.<\/p>\n

 <\/p>\n

The EU is considering introducing regulations to curb their energy use, as data usage climbs. For now, some data centre operators have formed a pact<\/a> to become climate neutral by 2030. They aim to improve energy efficiency, switch to clean energy sources, and explore ways to reuse excess heat.<\/p>\n

All these are important steps, because all data-hungry technologies have a price \u2013 even streaming a movie at home on high-definition TV, says Yilmaz. \u2018The price is energy consumption.\u2019<\/p>\n
