IBM was one of the first companies to offer cooling of server systems with liquid, and the heat energy they allocated was not in vain, but was used to heat office space - at least in Switzerland such energy saving methods worked without problems.
Care for nature has become an important part of the development policy for the American giant. All American data centers Apple, like the company headquarters, use only renewable energy sources. In general, the world's share of renewable energy for data centers does not exceed 96%, because in some regions, Apple's servers are operated at third-party leased sites. The company intends to spend about $ 1.8 billion on the construction of two data centers in Northern Europe: Denmark and Ireland.
In the first case, the heat generated by the server equipment will be used to heat the surrounding residential buildings. In addition, the data center will use methane to generate electricity, resulting from the processing of waste from livestock farms located in Denmark. In addition to methane, this technology allows to get organic fertilizers, which will be returned to farmers engaged in plant growing. From a local power grid, the Danish data center of Apple will not consume a watt of electricity.
The Irish data center of Apple will be powered by systems that generate electricity due to sea waves. The iPhone manufacturer also seeks to reuse the bulk of the structural materials used to produce its own products. Such a policy should help slow the depletion of the world's natural resources.
