Guam: Electricity production from oil, gas and coal sources (% of total)

Key figures

What the numbers say

In 2021, Guam's electricity production from oil, gas and coal sources (% of total) fell 0.11 percentage points on 2020 (from 95.3% to 95.2%).

Across the 20 yearly changes before that (2001 to 2020), the average change was −0.23 percentage points and a typical year strayed about 0.58 percentage points 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 0.25 percentage points in 2017 and the biggest yearly fall was 2.03 percentage points in 2016. The numbers show how large and when, not why; for the cause, look at what happened in that country in those years.

From 2012 to 2021 the straight-line trend is downward, about 0.63 percentage points a year. A straight line explains 88% of the movement over 10 observed years.

A straight-line projection, tested first

Extending that straight line gives about 92.96% for 2024. We show this only because the same method, fitted on earlier years, predicted 2019 to 2021 better than "no change" would have: its average miss was 0.27%, against 0.36% 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.

What this measures

The share of electricity production from oil, gas and coal sources of total electricity production. Sources of electricity refer to the inputs used to generate electricity. Oil refers to crude oil and petroleum products. Gas refers to natural gas but excludes natural gas liquids. Coal refers to all coal and brown coal, both primary (including hard coal and lignite-brown coal) and derived fuels (including patent fuel, coke oven coke, gas coke, coke oven gas, and blast furnace gas). Peat is also included in this category.

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