Natural Resources
Natural resources are materials or energy sources provided or found on Earth that are useful to humans; review our guide on the primary types of natural resources for full classifications. All industrial products originate from natural resources.
- Renewable resources: can be naturally replenished at rates faster than their consumption. Examples include solar radiation, geothermal heat, hydroelectric river flows, and living flora and fauna.
- Non-renewable resources: finite geological reserves that cannot regenerate on human timescales once extracted. Key examples include nickel, thermal coal, crude oil, natural gas, copper, and gold.

Oil and Gas Resources in Indonesia
Indonesia maintains substantial petroleum extraction, producing approximately 658,820 barrels per day in 2021 and ranking 24th globally. Historic onshore and offshore basins in Sumatra, East Kalimantan, and the Java Sea, overseen by state energy company Pertamina, support domestic refining.
Indonesia possesses vast natural gas reserves, yielding an annual extraction of 71,440 million cubic meters (ranking 14th globally). Major gas fields—such as Tangguh in Papua, Mahakam in East Kalimantan, and the Natuna Sea—support large-scale liquefied natural gas (LNG) export terminals.
Examples of Mineral Resources of Indonesia
Indonesia is one of the world’s leading producers of coal, ranking third in global production and standing as the world’s number one thermal coal exporter (surpassing 775 million tonnes produced in 2023). Mines in East Kalimantan, South Kalimantan, and South Sumatra supply global power utilities. Review our analysis on global mineral resources to contextualize Indonesia’s mining prominence.
In 2024, Indonesia produced 274 thousand tonnes of aluminium, ranking 24th globally. Bauxite extraction across West Kalimantan and the Riau Islands feeds newly constructed domestic alumina refineries.
Indonesia is the world’s seventh-largest gold producer, extracting 139 tonnes in 2019. The Grasberg mine in Papua, operated by PT Freeport Indonesia, is home to one of the largest gold reserves and largest copper deposits on the planet.
Water Resources of Indonesia
Indonesia boasts an enormous renewable freshwater volume of 2,019 km³ as of 2020, placing it eighth worldwide in freshwater abundance, with vital drainage basins including the Kapuas River in West Kalimantan and Lake Toba in North Sumatra. Explore our global report on water resources for comparative international data.
Average Rainfall and Soils of Indonesia
Indonesia experiences heavy equatorial rainfall, averaging 2,702 mm annually and ranking ninth globally in precipitation. Driven by the Intertropical Convergence Zone and monsoons, deep tropical weathering produces exceptionally fertile volcanic andosols across Java, Bali, and Sumatra, juxtaposed with extensive coastal peatlands (organosols) in Kalimantan and Papua that require careful fire and drainage management.
However, steep volcanic terrain combined with extreme monsoon rainfall makes deforested slopes highly susceptible to severe soil erosion and localized flash flooding.
Renewable Electricity and Hydropower Production in Indonesia
Indonesia generated 248,613 GWh of electricity in 2021, of which 19,414 GWh was supplied by hydroelectric facilities, led by the Saguling hydroelectric station in West Java with an installed capacity of 1,400 MW. For comprehensive perspective, see our guide on global energy resources.
Forest Resources of Indonesia
Indonesia is home to the world’s third-largest tropical rainforest, spanning Kalimantan, Sumatra, Sulawesi, and Papua. In 2020, forest cover reached 49.1% of national land area, encompassing 921,332 km². Discover more in our detailed analysis of forest resources.
Ranking eighth globally in forest area, Indonesia’s peat-swamp and lowland dipterocarp forests represent globally critical carbon sinks and irreplaceable biodiversity reserves.
Environmental Performance and Protection of Indonesia’s Natural Resources
In the 2024 Environmental Performance Index, Indonesia scored 35.8, ranking 151st globally according to the Yale Center for Environmental Law & Policy 2024 report. Terrestrial and marine protected areas cover 12.0% of land area, supported by expansive national park declarations and marine protected networks across the Coral Triangle.
