In 2018, the share of renewable energy sources (RES) in the use of fuels in the tertiary sector increased by 2.1% compared to the previous year, amounting to 58.3%, which is the highest value in the period 2010−2018. The increase was mainly driven by a 9% decline in the use of fuels in the tertiary sector. The achieved share of RES lagged behind the indicative annual target value by 0.7 percentage points. In order to achieve the target of a 61% share of RES in the use of fuels in the tertiary sector in 2020, this share will need to be increased by 2.7 percentage points, which is, on an annual basis, comparable to the growth in the share of renewable energy in 2017.
