IDN · 2024 energy mix · renewables 6.9% · fossil fuels 89.0%
Threat reading 47 of 100, classified HIGH THREAT, HOLDING. 31 events recorded here in the last seven days, 31 in the last thirty.
That number is computed from live feeds and moves. The live monitor is where to read it as of right now.
Where its energy comes from
| Coal | 43.8% |
|---|---|
| Oil | 29.4% |
| Gas | 15.8% |
| Other renewables | 4.6% |
| Hydro | 2.2% |
| Solar | 0.1% |
In 2024, renewables accounted for 6.9% and fossil fuels for 89.0%. On electricity traded with its neighbours, Indonesia is close to balanced on electricity trade.
Sources under one per cent of the mix are left out of the table rather than listed as a row of zeroes. Percentages are shares of a country's primary energy, not of the power it generates.

What the threat reading is made of
| Conflict | 14 |
|---|---|
| Unrest | 0 |
| Security | 10 |
| Spillover from neighbours | 0 |
| Natural hazard | 66 |
| Resilience | 70 |
Each is 0 to 100. Resilience runs the other way to the rest: a high number is a country better able to absorb a shock, not a country in more trouble.
