|METHODS OF CALCULATING ENERGY EFFICIENCY THROUGH ENERGY INTENSITY - ROMANIA|
|Author(s): Nela Steliac|
|DOI: 10.4316/EJAFB.2023.1122||Abstract: In the current economic and geopolitical context, energy efficiency is an important goal for every nation. Energy security, economic competitiveness and reduced environmental pollution depend on it. Energy intensity is the indicator most often used to assess energy efficiency in a national economy. It can be calculated not only at the aggregate (national) level giving an overall picture of energy efficiency, but also at the disaggregated (sectoral and sub-sectoral) level giving a detailed picture by sector and sub-sector of activity. This paper aims to highlight the different ways of calculating primary and final energy intensity with an example at the Romanian level for the period 2011-2021. The analysis of this indicator revealed that the transport sector is the least energy efficient. However, the energy intensity trend in transport is downward. At the opposite pole, the most efficient sector is the other activities sector, which includes the rest of the services. With small exceptions, however, there is a general downward trend in final energy consumption per $1000 gross value added by sector. The same downward trend was also evident for primary energy intensity.|
