Bulgaria: Electricity production from oil sources (% of total)

Key figures

What the numbers say

In 2024, Bulgaria's electricity production from oil sources (% of total) rose 0.24 percentage points on 2023 (from 0.7% to 0.94%).

Across the 30 yearly changes before that (1994 to 2023), the average change was −0.12 percentage points and a typical year strayed about 0.4 percentage points from that (the standard deviation). This year's change was 0.9 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 0.92 percentage points in 1993 and the biggest yearly fall was 0.96 percentage points in 1997. 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 upward, about 0.03 percentage points a year. A straight line explains 38% of the movement over 10 observed years.

What this measures

The share of electricity production from oil sources of total electricity production. Sources of electricity refer to the inputs used to generate electricity. Oil refers to crude oil and petroleum products.

Limitations: IEA occasionally revises its time series to reflect political changes. For example, the IEA has constructed historical energy statistics for countries of the former Soviet Union. In addition, energy statistics for other countries have undergone continuous changes in coverage or methodology in recent years as more detailed energy accounts have become available. Breaks in series are therefore unavoidable. Data on access to electricity are collected by the IEA from industry, national surveys, and international sources.

Regional and income-group figures are computed by the World Bank as a weighted average using total electricity production as weights.
