Tonga's electricity production from renewable sources, excluding hydroelectric (kWh) was 10.49 million in 2021, the latest year in the World Bank's World Development Indicators. That is up 6,456% from 160,000 in 2011 (51.94% a year on average, compounded).

What the numbers say
In 2021, Tonga's electricity production from renewable sources, excluding hydroelectric (kWh) fell 0.1% on 2020 (from 10.5 million to 10.49 million).
Across the 20 yearly changes before that (2001 to 2020), the average change was +50.3% and a typical year strayed about 141.9% from that (the standard deviation). This year's change was 0.4 standard deviations below 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 637.5% in 2012 and the biggest yearly fall was 0.1% in 2021. 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 upward, about 1.05 million a year. A straight line explains 98% 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 13.9 million 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 1.56 million, against 2.59 million 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 2021, Tonga had the 159th highest value of the 208 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
Electricity production from renewable sources in kilowatt-hour (kWh), excluding hydroelectric, includes geothermal, solar, tides, wind, biomass, and biofuels.
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.
Regional and income-group figures are computed by the World Bank as a sum.
