The district heating systems are mainly monopolies controlled by local politicians or private companies. In practice the owners of the houses with district heating system have no influence in the choice of energy sources or prices. For example, the politicians of Espoo sold the public district heating system for the big energy company Fortum in 2006. Since then the district heating prices in Espoo have kept rising and Espoo city has lost tens of millions of euros annually in the energy business compared to nearby cities Helsinki and Vantaa. Further the tax payers have higher district heating costs. Fortum uses 100% fossil energy of natural gas from Russia for district heating. In 2010 Fortum lobbied for the total restriction by law of all renewable energy alternatives within the district heating areas. This has not been realised, but the renewable alternatives have more control by the public permission system since 2010. The total energy company deal from Espoo to Fortum was worth of 365 million euros for Espoo. The investment of these funds have not given the claimed 5-6% return. In fact, 15 million € was invested in Kaupthing that was in bankrupt in 9.10.2008. Further Espoo lent a sum of 82 million euros to the state for a motor way project (Kehä 1) with no interest at all during 2008-2013. Even though the commercial investors have received large compensations for their work from Espoo city energy gains, the media have given the impression that the return of funds have not compensated the tax payers costs. In short, the deal can be considers successful for the nuclear company Fortum, but unsuccessful for the Espoo tax payers. There is no effective free competition for district heating in place. Further, one hardly can avoid the impression that the energy and construction companies have mutual interests to promote the dependency on Russian energy. Neither Finnish construction nor energy companies have at least until end 2010 actively promoted higher energy efficiency standards and alternative energy source obligations. Among the supporters of solar heating in Finland is architect Bruno Erat who successfully applied solar heating in Finland in the 1970s. Bruno Erat built in 1978 the first low energy building in Finland. In 2010 a new low energy house in Heinola Finland saved 70% in warming expenses compared to the equal average warming expenses. According to Mikko Saari (VTT 2004) a low energy block of flats in Finland would save 400 000–1 000 000 € in warming costs in 50 years with 3-6% annual energy price increase. There is an ongoing significant construction boom in Finland based on old and high energy demand construction standards since the energy cost payment is paid by the users and future generations but not the construction industry nor its leaders early retirement payrolls.
