There is currently a lot of discussion surrounding the sustainability and energy consumption of data centers. Since many of the processes we use today run through data centers, they do indeed require a significant amount of energy. But despite that, data centers are more environmentally friendly and sustainable than you might think. In England, for example, they’re working on a project to use the residual heat from data centers to heat homes!
Heating businesses and homes through data centers
The British government is set to invest 41.4 million euros in its new project. The idea is to use waste heat from data centers to heat commercial buildings and homes. The goal is to connect 10,000 new-build homes in London to the district heating network, along with approximately 250,000 square meters of commercial space. The British Ministry recently presented the plans, but they appear not to be fully developed yet. For example, it is not yet clear whether they intend to use only waste heat from data centers that have yet to be built, or whether the plans also involve diverting cooling water from existing data centers.
Plans for data centers in the Netherlands
In the Netherlands, there are also plans to use data centers for a similar purpose in the future. In Groningen, negotiations are underway to use cooling water from Bytesnet’s data centers to heat several thousand homes. However, many people are quite critical of these plans. The untreated cooling water from the data centers isn’t warm enough on its own to heat homes. That means a heat pump would also be needed to reach a high enough temperature. And of course, that consumes energy too!
Data centers in the Netherlands that already heat their buildings
There are currently about 184 data centers in the Netherlands, covering a total area of approximately 40 hectares. That area is equivalent to 60 soccer fields. In some parts of the country, these data centers are already being used to heat buildings. In Amsterdam, for example, 1,300 apartments are heated using residual heat from data centers, and in Eindhoven, 40 office buildings. If the plans in Groningen mentioned in the previous paragraph go ahead, another 10,000 homes will be added to that total. Unfortunately, the likelihood that all homes in the Netherlands will ever be heated this way is small. This would, in fact, pose a significant logistical challenge. Still, every building that can be heated this way is, of course, a welcome addition.
Do you see a future in this plan?
