Conclusions

A. Sooner or later the heating prices in Europe will be equal.

B. Following the statistical data, Lithuania undergoes losses in the amount of 0.7 million EUR within one day of the heating season. This considerable amount of losses occure due to irrational use of heat energy, poor attitude towards the renovation of buildings and engineering systems, etc. Therefore according to the Conclusion A, it is possible to forecast that the losses will be increasing.
