A Data Center with zero water use, 100% renewable energy (1.17g CO2/kWh) and a 1.15 PUE, all made from wood

The EcoDataCenter in Sweden: There are two key measures of datacentre performance. One is carbon usage effectiveness (CUE): the carbon emissions for each kWh of energy consumed. The average for US datacentres is 414g CO2/kWh, the European Union’s is 263g CO2/kWh, EcoDataCenter’s is 1.17g CO2/kWh. Another key measure is power usage effectiveness (PUE); how efficiently the datacentre uses the power going into it. The EU average is 1.36 (where a score of 1 would be 100% efficiency), EcoDataCenter’s is 1.15. Pretty damn amazing, if you ask me (although I do have a patriotic stake in promoting Sweden - give us more datacenters and cheaper compute! ;) ). Oh, and we've got a huge energy surplus up north, which is getting lost being sold south to the EU. Better to use it up locally instead of building datacenters in Germany or France.
