+Avoiding CO2 emissions in data storage is a daily task, too
+---
+body:
+
+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](https://datacenterlight.ch), 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](https://ungleich.ch) is very proud to offer a variety of
+products that are built with sustainability in mind:
+
+* [Sustainable Data Storage: Glarnercloud )(https://glarnercloud.ch)
+* [Sustainable Virtual Private Servers](https://datacenterlight.ch)
+* [Sustainable IPv6 only VPS](https://ipv6onlyhosting.com/)
+* [Sustainable IPv6 VPNs](https://ipv6vpn.ch)
+* [Sustainable IPv6 Backup](https://ungleich.ch/en-us/cms/ipv6-backup/)

+If you have any questions about it, you can reach us at
+**sustainability at ungleich.ch** or in the [ungleich
+chat](https://chat.ungleich.ch).
