In 2024, renewables accounted for 15.3% and fossil fuels for 63.3%. On electricity traded with its neighbours, Bulgaria is close to balanced on electricity trade.

Sources under one per cent of the mix are left out of the table rather than listed as a row of zeroes. Percentages are shares of a country's primary energy, not of the power it generates.

A dash means NOAA recorded no number, not that nobody died. Older entries are fewer because fewer were written down, not because less happened.
