How to store your data without CO2 emission

Posted on 2019-11-20 by ungleich

When we talk about climate change or sustainability, we usually think about factories or cars. What we usually don't anticipate is how much we actually contribute to the climate change by our digital behaviour.

How data is stored

Your data is usually stored in one of the many data centers in the world. To save your data, multiple disk or even multiple servers are used to ensure that your data is safely stored.

When you open up your mobile phone to browse pictures or to read your email, you access the servers to retrieve your data.

How data centers are operated

Most data centers use energy from the grid. This energy can be either produced by coal, nuclear power or renewable energy. Unfortunately, most of them don't run on renewable energy. Some do buy CO2 certificates to compensate this fact.

Energy in a data center is spent on one side for actually running the servers that store your data and on cooling on the other hand. The amount of energy used for cooling can be quite significant, too.

So even if you are living a very green and sustainable way, you might be contributing to CO2 emissions by using your default data storage.

An alternative: the sustainable way of saving data

So how can we tackle this situation? We have worked hard here in Switzerland to create the Data Center Light, a complete alternative approach to save as much CO2 emissions, as possible.

And this is how it is done:

  • instead of buying certificates, we use 100% renewable energy
  • instead of buying energy, we produce it locally (using PV and a local hydro power plant)
  • instead of building new data centers, we modernise existing factory halls
  • instead of buying new servers, we buy 2nd hand (with new disks/ssds)

The sustainable data center

With this approach, there is practically no CO2 emission from power consumption and also the grey energy is minimised. The team of ungleich is very proud to offer a variety of products that are built with sustainability in mind:

In our opinion, we can only reach sustainability, if we take actions in all fields of our daily life.

In case you are looking for an affordable way of testing the products, you should not miss the Black IPv6 Friday, which has up to 50% discount on the products.
