The energy consumption of datacenters is increasing exponentially. Local community heating is required to heat houses. The talk will give an overview of the existing problems and examples how data centers can be integrated into green power generation to heating concepts producing data center services en passant.

3% of global electricity consumption today and are projected to touch 4% by 2030. The average hyperscale facility consumes 20-50MW annually – theoretically enough electricity to power up to 37,000 homes[1].

Newer concepts reduce the energy for cooling to zero and integrate the datacenter into photovoltaic energy sources and local community heating as a sink[2]. Open source concepts allow to run a local cloud zone in this location regaining control of citizen data.
