The chart shows how much electricity is generated in Tonga from various energy sources. This is typically referred to as energy mix or power generation mix. The numbers on this page are our calculations based on data from the U.S. Energy Information Administration. Looking at the last five years of available data ending in 2020, the electricity generation in Tonga, measured in billion kilowatthours per year, is as follows: 0.06 from fossil fuels including coal, natural gas, and oil; 0 from wind; 0 from solar installations; 0 from hydro; 0 from nuclear power plants; and 0 from geothermal sources.

The table shows the relative importance of the various energy sources in terms of their percent of the total electricity generation in Tonga. The calculations are based on the latest five years of available data. For comparison, the table also shows the average values for the world and for Australia.

In Australia, the main energy source is fossil fuels with 73.1 percent of the total energy produced. For the world as a whole, fossil fuels are also the main energy source with 62.05 percent. In Tonga the greatest share of electricity is generated from fossil fuels as well with 100 percent A greater percent of the electricity in Tonga is produced from fossil fuels compared to the rest of the world.
