ENERGY STRATEGY OF THE REPUBLIC OF BULGARIA UNTIL 2020. The national target must be achieved by increasing the production of electricity from renewable sources, the final consumption of energy from renewable sources for heating and cooling and the consumption of energy from renewable sources in transport. Of the sectoral goals, only the one for consumption of renewable sources in the transport sector is mandatory - a 10 percent share of energy from renewable sources in transport consumption by 2020. The prices of energy produced from renewable sources are the only ones that will decrease in the longer term given the progress of production technologies. The prices of traditional energy resources will increase due to the depletion of fossil resources and their environmental characteristics. These two trends will lead to a convergence of existing price differences. In the next decade, however, the need for support for the entry of RES is not expected to disappear.
