Bulgaria: Energy use (kg of oil equivalent) per $1,000 GDP (constant 2021 PPP)

Key figures

What the numbers say

In 2024, Bulgaria's energy use (kg of oil equivalent) per $1,000 GDP (constant 2021 PPP) fell 2.96 on 2023 (from 79.17 to 76.21).

Across the 30 yearly changes before that (1994 to 2023), the average change was −4.06 and a typical year strayed about 6.79 from that (the standard deviation). This year's change was 0.2 standard deviations above that average, so it was an ordinary year: it sits within the range of normal year-to-year movement.

On record, the biggest yearly rise was 16.35 in 1993 and the biggest yearly fall was 27.53 in 1991. The numbers show how large and when, not why; for the cause, look at what happened in that country in those years.

From 2015 to 2024 the straight-line trend is downward, about 3.09 a year. A straight line explains 89% of the movement over 10 observed years.

Worked out from the yearly values above. How the checks work: standard deviation, z-scores and straight-line trends.

A straight-line projection, tested first

Extending that straight line gives about 74.57 for 2027. We show this only because the same method, fitted on earlier years, predicted 2022 to 2024 better than "no change" would have: its average miss was 7.01, against 11.98 for assuming no change. Treat it as a continuation of the recent pattern, not a forecast of events: it cannot see a recession, a policy change or a revision to the data.

How it compares

In 2024, Bulgaria had the 68th highest value of the 141 economies reporting that year. Higher is not always better: for some indicators the lowest value is the one to aim for. See the full ranking.

What this measures

Energy use per PPP GDP is the kilogram of oil equivalent of energy use per constant PPP GDP. Energy use refers to use of primary energy before transformation to other end-use fuels, which is equal to indigenous production plus imports and stock changes, minus exports and fuels supplied to ships and aircraft engaged in international transport. PPP GDP is gross domestic product converted to 2021 constant international dollars using purchasing power parity rates. An international dollar has the same purchasing power over GDP as a U.S. dollar has in the United States.

Regional and income-group figures are computed by the World Bank as a weighted average.
