North America already is in a strong position on district heating – especially on university campuses. This issue of Hot Cool introduces the situation in both the USA and Canada. From our side, we welcome a close cooperation with the North American district heating promoters and look forward to expanding our cooperation further. A few well-known multinational companies – originating from the US – will play an active role in keeping district heating green and keep costs down in Denmark. Facebook and Apple datacentres will open in Denmark within a few years. These can provide a lot of heating to nearby small and large cities – if Danish legislation allows. The companies, the people living in Viborg and Odense, and society as a whole can benefit from cooperation through e.g. lowering cost for the companies, creating a greener profile for all, and, not least, can play a role in creating and sustaining jobs.
