summary energy [kWh/d/p] energy [%] energy [TWh] renewables and biofuels


This page shows the energy use for Slovenia, using 0.047 percent of world energy production for 2.08 million inhabitants in 2019. Energy is typically specified in Million metric Ton of Oil Equivalent [Mtoe] for large quantities. This work prefers to use TeraWatt-hours (TWh) instead, which is obtained by multiplying the a value expressed in Mtoe with a factor 11.63 . To allow an easy comparison between countries, we normalize the TWh value to kiloWatt-hour per day per person (kWh/d/p) - David MacKay introduced this energy unit in [5]. Day to day energy production or consumption can fluctuate from a kWh/d/p value, for example space heating consumes more energy in the winter season.

These values are summarized in table 0.1 . The first two columns show the gross inland energy consumption and gross renewable and biofuel consumptions. We do so since some renewable and biofuel sources are converted to electricity for final energy consumption. The third column shows the total final energy consumption of Slovenia. The fourth column shows the electricity consumption, which is a part of the final energy consumption.

The main data source for this page are the Eurostat energy balances, edition April 2021. A population plot of Slovenia and a list of data source references are available below.

Disclaimer: This work provides a summary of the original data, converting ktoe (kilo ton oil equivalent) values to other energy units such as relative percentages, TWh (TeraWatt-hours) and normalized kWh/d/p (kiloWatt-hours per day per person) values. Values are rounded to 3 significant digits. Eurostat is not responsible for data conversion or rounding errors in doing so.

Other visualizations: Since 2022 Eurostat provides a set of interactive visualization tools for energy at ec.europa.eu/eurostat/web/energy/visualisations. For energy balances Total energy supply is used there, which is equivalent to the Gross inland consumption minus the energy of international aviation.
