Renewable Energy – Solutions for application in the communal energy infrastructure
This brochure contains a selection of successful renewable energy solutions suitable for a range of applications for local and national municipalities and economies. The main energy end-use sectors and the current state of the energy transition are briefly explained to provide readers with an understanding of the transformation of the greater energy system. The renewable energy technology options are explained, including their relevance and applications for municipalities. Finally, a selection of exemplary projects that have been successfully implemented in Europe, the Russian Federation and Central Asia, are included to demonstrate real applications and use-cases for renewable solutions. Renewable energies are cheap, clean and versatile.

Russia: Secondary school heats its build<strong>in</strong>gs with geo<strong>the</strong>rmal heatpumps<br />
The village school uses geo<strong>the</strong>rmal <strong>energy</strong> <strong>for</strong> heat<strong>in</strong>g and hot water supply.<br />
The newly built village school of Versh<strong>in</strong><strong>in</strong>o <strong>in</strong> <strong>the</strong><br />
Tomsk region of Siberia has been heated and supplied<br />
with hot water by geo<strong>the</strong>rmal heat pumps s<strong>in</strong>ce 2014.<br />
With <strong>the</strong> help of 28-vertical geo<strong>the</strong>rmal probes that<br />
reach down approximately 50 metres, <strong>the</strong> plant extracts<br />
heat from <strong>the</strong> ground. Two heat pumps raise <strong>the</strong><br />
low temperature level from <strong>the</strong> ground to 55 degrees<br />
Celsius so that <strong>the</strong> <strong>energy</strong> can be used <strong>for</strong> heat<strong>in</strong>g and<br />
hot water production. The temperature can be <strong>in</strong>creased<br />
up to 100 °C if necessary. Toge<strong>the</strong>r, <strong>the</strong> two heat pumps<br />
provide a heat<strong>in</strong>g output of 84 kilowatts. To generate<br />
four kilowatt hours of heat<strong>in</strong>g, only one kilowatt hour<br />
of electrical <strong>energy</strong> needs to be used. The 1,454 square<br />
metre school build<strong>in</strong>g is heated via underfloor heat<strong>in</strong>g<br />
comb<strong>in</strong>ed with room <strong>the</strong>rmostats. The entire system<br />
was implemented by Ecoklimat, a Siberian company<br />
specialis<strong>in</strong>g <strong>in</strong> heat pump heat<strong>in</strong>g systems.<br />
The 28-vertical geo<strong>the</strong>rmal probes reach down <strong>in</strong>to <strong>the</strong> earth<br />
approximately 50 metres.<br />
If <strong>the</strong> school were heated with fossil fuels, 19 tonnes<br />
of natural gas or 25 tonnes of diesel would be needed<br />
annually. The modern heat<strong>in</strong>g technology pays <strong>for</strong> itself<br />
with<strong>in</strong> a few years and ensures a high degree of <strong>in</strong>dependence<br />
from fossil fuels.<br />
The two heat pumps with a heat<strong>in</strong>g capacity of 84 kilowatts.
