 So how do the small and renewable zero carbon digital services look in reality? We can take us as one of the examples.  
 In this small Alpine village we are located at, we are running [servers with only renewable energy.](https://datacenterlight.ch/en-us/cms/hydropower/) That is 99.9% hydropower and 0.1% solar power. Our case is a bit special because we brought our servers into old buildings that used to work as spinning and weaving factories that are built many years ago when Switzerland hosted a strong textile industry. Now the textile industry all moved out of the country looking for lower labour cost, leaving vast empty industrial buildings. Thanks to the infrastructure previously built, we directly produce the hydroelectricity a few meters away from our servers, by the water melted from the glacier on the Alps.  
-What we do is we only use recycled servers, so we can extend their lifecycle as long as possible before they end up in the landfill. And we do not waste energy for cooling the servers: the mountain temperature is cool enough throughout the year, and the big space we have helps the servers from being overheated.
