contributing to social and territorial cohesion. Bulgaria aims to reduce the energy intensity of GDP by 50% by 2020, reaching a value of this indicator of 456 Tne/MBO5 compared to its level in 2005, 913.3 The/MBO. The implementation of the measures and policies to be approved with the Energy Strategy of the Republic of Bulgaria 2020 regarding the increase in energy efficiency aims to lead to an improvement in energy efficiency by approximately 25%, or a saving of more than 5 million tons of primary energy compared with the baseline development scenario by 2020. Despite this positive trend, the energy intensity of the national GDP is 89% higher than the EU average (measured by gross domestic energy consumption per unit of GDP and considering purchasing power parity) 302 tne/ 05 compared to 160 tne/ M 05 in the EU. Significantly lower - 42.6%, are the differences between the national and European indicators, measured by final energy consumption. This is an indicator of inefficient use of primary energy resources, which is also confirmed by the ratio between the received energy and the input resources. This ratio for the national energy balance is 49%, and for Europe - 64%. For comparison, this difference of 15 points shows that 3 million tons more energy resources are consumed annually in Bulgaria, representing ~900 million euros more energy costs per year.
