In Helsinki (FI),The Finnish IT company Academica has installed a new 2MW database server centre. Water warmed while cooling the servers will go on to provide heat for 500 homes or 1,000 flats in a city that often suffers winters of -20C. After the heat is extracted, the water will be recycled back to cool the servers again.

In 2007, on recommendation of Danish experts, the city council of Frederikshavn (DK) unanimously decided to become the town of "100% renewable energy" by 2015.
The methodology used is mapping the existing energy system, including transport, and defining the share of renewable energy.

In Frankfurt (DE), cogeneration units are frequently used to ensure heat supply for residential areas through mini-district heating. In parallel of promoting small decentralized cogeneration, the city wishes to further develop the district heating cogeneration. Several large areas of more than 2 million square meters are connected to the existing district heating networks. One of the main tasks for the city is to develop energy plans for new neighbourhoods in coordination with other city departments and investors.

District heating produced from biomass in the
Combined Heat and Power (CHP) plant in Växjö (SE) is used to produce cooling for the hospital and the university via absorption chillers.
The hospital and the university are connected, with plans to extend the district cooling system to more customers later on. Two full
scale chillers in the CHP plant, each of 2 MW, produce cooling that is distributed in pipes to the hospital and the university area.

A new European project SUNSTORE4 aims to demonstrate an innovative cost efficient and reliable 100% renewable energy supply system for a large scale heating system based on 55% of solar energy and 45% of biomass energy.
The Martsal (DK) district heating will experiment this project.
Finaced by the 7th Frameworth Programme of the European Union, this project is coordinated by Marstal Fjernvarme a.m.b.a., SUNMARK A/S, Euro Therm A/S, Advansor, Steinbeis Innovation GmbH, Energy Management AB, BIOS Bioenergiesysteme GmbH, EuroHeat and Power, CityPlan spol. s r.o., Ambiente Italia and PlanEnergi.
