Jakarta, INTI - Why Indonesia Needs Renewable Energy Amid the challenges of climate change and global pressure to reduce reliance on fossil fuels, Indonesia has a tremendous opportunity to shift to renewable energy. One of the most promising renewable energy sources in Indonesia is geothermal energy, which harnesses the Earth’s internal heat.
Indonesia’s geothermal energy potential is vast. Situated within the Pacific Ring of Fire, the country boasts abundant geothermal resources. However, to date, its utilization remains limited. Why is geothermal energy considered one of the key solutions for Indonesia’s future energy needs? And how does it compare to other countries with similar geothermal potential?
Why Geothermal Energy is the Right Solution for Indonesia Indonesia's vast geothermal resources can reduce its dependence on depleting fossil fuels. Geothermal energy is a renewable source that can be relied upon year-round, as it is not affected by weather conditions like solar or wind energy.
Moreover, geothermal power plants have a very low carbon footprint, making them a more environmentally friendly option. As a nation committed to reducing carbon emissions, Indonesia can achieve its emission reduction targets faster by fully utilizing its geothermal potential.
Geothermal Development in Indonesia: Where Are We Now? According to a report from the Ministry of Energy and Mineral Resources (ESDM), Indonesia’s geothermal potential is estimated at 23.9 gigawatts (GW). However, actual utilization currently stands at only 2.3 GW, far below the available potential. This indicates a significant gap that must be filled by the government and investors.
Several geothermal projects in Indonesia are already operational, including in West Java, with geothermal power plants at Kamojang and Mount Salak. Outside Java, a geothermal project in Lahendong, North Sulawesi, has also made a significant contribution to the national electricity supply.
Challenges to Geothermal Development in Indonesia Geothermal energy development is not without challenges. One of the biggest barriers is the high upfront investment costs, particularly for initial exploration and drilling. Drilling in uncertain locations requires significant capital and is often seen as a high-risk venture by investors.
Additionally, many regions with geothermal potential are in remote areas with limited infrastructure. This adds complexity in terms of logistics and project development. Furthermore, long and cumbersome permitting processes frequently delay the progress of geothermal development.
Lessons from Other Countries: Iceland and the Philippines Indonesia can learn from other countries that have successfully harnessed their geothermal potential. Iceland, for example, meets almost all of its electricity needs through renewable energy, including geothermal. The country capitalizes on its volcanic activity to generate electricity and provide heat for its citizens.
In Southeast Asia, The Philippines has also become a major player in geothermal energy development. The country has an installed capacity of 1.9 GW, making it one of the largest users of geothermal energy in the world. The success of The Philippines is supported by proactive government policies and stable investment in renewable energy.
The Future of Geothermal Energy in Indonesia Indonesia has a golden opportunity to become a leader in geothermal energy development. With abundant potential and the urgency of global energy challenges, geothermal energy could not only solve the national energy crisis but also contribute to global efforts in combating climate change.
However, to realize its full potential, more than just goodwill is required. The government must streamline the permitting process, provide incentives to investors, and improve infrastructure in geothermal-rich regions. With these steps, geothermal energy could become the backbone of Indonesia’s energy transition towards a more sustainable future.
