Singapore: GDP per unit of energy use (constant 2021 PPP $ per kg of oil equivalent)

Key figures

What the numbers say

In 2024, Singapore's GDP per unit of energy use (constant 2021 PPP $ per kg of oil equivalent) rose 0.58 on 2023 (from 25.07 to 25.65).

Across the 30 yearly changes before that (1994 to 2023), the average change was +0.51 and a typical year strayed about 2.08 from that (the standard deviation). This year's change was 0.0 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 6.08 in 2005 and the biggest yearly fall was 3.19 in 2012. 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 0.55 a year. A straight line explains 80% of the movement over 10 observed years.

What this measures

GDP per unit of energy use is the PPP GDP per kilogram of oil equivalent of energy use. 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.

Limitations: The IEA makes these estimates in consultation with national statistical offices, oil companies, electric utilities, and national energy experts. The IEA occasionally revises its time series to reflect political changes, and energy statistics undergo continual changes in coverage or methodology as more detailed energy accounts become available. Breaks in series are therefore unavoidable.

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