Renewable Energy in Indonesia: Here’s the Solutions & Opportunities!

Indonesia has enormous renewable energy potential. With abundant resources, vast geothermal and strong wind reserves, widespread adoption is achievable.

Yet most of Indonesia’s energy still relies on fossil fuels like oil and coal. As climate change intensifies and the nation targets Net Zero Emissions by 2060, accelerating the adoption of renewable energy is essential.

Developing renewables helps the environment and spurs new economic growth. What is Indonesia’s renewable energy potential? Find out in this article.

What Is Renewable Energy

Before discussing the Indonesian context, you first need to understand what renewable energy actually means. Renewable energy refers to energy sources derived from nature and replenished naturally within a relatively short time.

This is certainly different from fossil fuels, which are limited and contribute significantly to carbon emissions. Renewable energy, therefore, offers a more environmentally friendly solution. Some types of renewable energy include solar, wind, hydropower, geothermal, and bioenergy.

Renewable Energy Potential in Indonesia

Indonesia is among the countries with the world's largest renewable energy potential. Below is an overview of Indonesia's renewable energy potential.

• Solar Energy: 207.8 GW
• Hydropower: 75 GW
• Wind Energy: 60.6 GW
• Bioenergy: 32.6 GW
• Geothermal Energy: 23.9 GW
• Ocean Wave Energy: 17.9 GW

Currently, several regions in Indonesia have become centers of renewable energy development, including East Nusa Tenggara (NTT), West Nusa Tenggara (NTB), Sumatra Island, and Sulawesi Island. This geographical distribution makes renewable energy not only a solution for decarbonization but also a way to support more equitable development across different regions.

Why Is Renewable Energy Important for Indonesia?

Indonesia's growing population, urbanization, and industrialization are driving higher energy demand. As a result, developing renewable energy is now an urgent priority for several reasons:

• Reducing Dependence on Fossil Fuels: With limited petroleum and natural gas reserves, renewable energy offers a more sustainable energy supply.
• Supporting the Net Zero Emissions Target: The government is advancing the energy transition to lower carbon emissions and meeting global climate commitments.
• Enhancing National Energy Security: Using local energy sources reduces reliance on imports.
• Creating New Economic Opportunities: Renewable energy projects generate jobs in construction, manufacturing, technology, and operations.

Challenges in Developing Renewable Energy in Indonesia

Despite its potential, Indonesia still faces several challenges in renewable energy development, such as:

• Investment Needs: Developing renewable energy infrastructure requires substantial initial investment.
• Electrical Infrastructure: Many regions lack transmission grids that can support new renewable energy plants.
• Regulations and Permitting: Faster permitting processes are essential to accelerate project implementation.
• Energy Storage Technology: Solar and wind energy require storage solutions to maintain a stable electricity supply.
• Awareness and Adoption: Greater use of renewable energy in homes and businesses should be encouraged through education and incentives.

Solutions and Innovations Toward Green Energy

Despite the challenges, various solutions continue to be developed to accelerate the energy transition. Below are several steps currently being implemented to support renewable energy development in Indonesia.

• Strengthening partnerships between the government and the private sector through large-scale renewable energy projects.
• Developing energy storage technologies, such as industrial-scale batteries.
• Digitalizing electricity systems through smart grid technology.

The more stakeholders involved, the greater the opportunity for Indonesia to reduce its dependence on fossil energy.

Economic Opportunities and Renewable Energy

Besides its positive environmental impact, renewable energy development in Indonesia also opens significant economic opportunities, such as:

• Creation of green jobs in energy installation, maintenance, and technology innovation.
• Growth of MSMEs in household-scale solar panel sectors and local bioenergy industries.
• Economic diversification in rural areas, especially in remote regions with high natural energy potential.
• Foreign investment is entering clean energy power plant projects in Indonesia.

With the right approach, renewable energy can become a key pillar in Indonesia’s economic transformation.

What Role Does the Business Sector Play in Supporting Renewable Energy?

The private sector is essential to accelerating the national energy transition. Its contributions include:

• Using electricity from renewable energy sources
• Installing solar panels at operational facilities
• Investing in clean energy projects
• Developing environmentally friendly technologies
• Implementing ESG (Environmental, Social, and Governance) strategies

Collaboration among government, business, and the public will enable faster and more sustainable renewable energy development.

Support Renewable Energy Development for a Sustainable Indonesia

The development of renewable energy in Indonesia is part of a long-term vision to create a better future. Indonesia already has the fundamental assets needed to achieve this goal, including abundant natural resources, a strategic geographical location, and supportive government policies.

However, without active participation from all levels of society, this transition may not run optimally. Therefore, as green initiatives and innovative solutions grow, it is time for us to move together toward a cleaner, fairer, and more sustainable energy future.

As a company with a broad business ecosystem, Astra plays a strategic role in promoting sustainability. Through its sustainability initiatives, Astra has integrated environmental issues into its operational activities, including renewable energy development.
