A recent study by the institute predicted that in such a business-as-usual situation, renewable energy would make up only 23 percent of the country’s energy consumption by 2050. The National General Energy Planning (RUEN) road map stipulates that green energy should make up 31 percent of the mix by that year.

The IESR has urged the government to revise the RUEN’s “disproportional” targets. IESR researcher Agus Tampubolon said they were based on incorrect economic assumptions in a statement on Wednesday.

The study adds to a growing body of evidence that Indonesia’s energy transition is moving too slowly and that without major policy changes, the country will miss its long-term green energy commitments. Regulations stipulate that Indonesia should have reached 17.5 percent renewable energy by 2019, but only 12.36 percent of the country’s energy use that year came from renewable sources.

The forecasts highlight the country’s reliance on conventional fossil fuels, reflected in a number of government policies, such as caps on fossil fuel prices and purchase guarantees for coal plants.

The National Energy Board (DEN), which oversees the RUEN, estimates that Indonesia’s green energy mix, expressed in million tons of oil equivalent (mtoe), was 9.15 percent last year, markedly higher than the 4.4 percent in 2015, when the road map was instated.
