Geothermal Powerhouse: Indonesia’s Booming Green Giant
Indonesia isn’t just known for its stunning landscapes and vibrant culture; it’s also a geothermal energy powerhouse!
Nestled on the Ring of Fire, the country boasts the world’s largest estimated geothermal potential, with a whopping 23.7 gigawatts (GW) across 300 identified sites. That’s like harnessing the power of over 23 million homes!
Leading the Charge:
Despite its immense potential, Indonesia currently utilizes only a fraction of its geothermal capacity, ranking second globally with 2,130.7 MW of installed capacity. But the country is on a mission to change that. The government has ambitious plans to triple its geothermal capacity within the next decade, driven by:
- Energy Security: Geothermal offers a reliable, baseload source of power, crucial for a rapidly growing economy like Indonesia’s.
- Environmental Sustainability: Unlike fossil fuels, geothermal energy is clean and renewable, reducing greenhouse gas emissions and air pollution.
- Economic Opportunities: The sector attracts significant foreign investment and creates high-skilled jobs.
Challenges and Opportunities:
While the future looks bright, challenges remain. High upfront costs, complex exploration and development processes, and land acquisition issues can hinder progress. To overcome these hurdles, Indonesia needs:
- Streamlined regulations and licensing procedures to expedite project development.
- Enhanced financial incentives to attract more investments, particularly for exploration and drilling.
- Technology innovation to improve efficiency and reduce costs.
- Community engagement to ensure local communities benefit from the development and address concerns.
The Path Forward:
Indonesia’s geothermal journey is an inspiring story of potential and progress. With continued commitment from the government, industry, and international partners, the country can unlock its geothermal potential and become a true leader in clean and sustainable energy production, not just for itself but for the entire region.
Geothermal Power Plants in Indonesia: A Booming Green Energy Landscape
Indonesia’s geothermal power sector is one of the fastest-growing in the world, thanks to its abundant geothermal resources and commitment to clean energy. Here’s a list of some of the major geothermal power plants in Indonesia, along with their capacities:

New ACORE Investor Survey Report Kicks Off 2026 Finance Forum
New York City, NY – A new report from ACORE shows that clean energy investors and developers largely plan to increase their investments in 2026 but cite policy, regulatory, and interconnection uncertainty as the biggest risks to their investment strategy after this year.
In its Navigating Uncertainty: Clean Energy Investment Trends (2026-2029) report, ACORE shares market sentiment analysis gathered from surveys of 36 leaders at U.S. and multinational companies that invested billions in the U.S. clean energy market in 2025.
Topline takeaways from the report include:
- Respondents identified federal regulatory and policy risks and interconnection uncertainty and costs as the top risks facing clean energy investments.
- Capital providers continue to view utility-scale solar and energy storage as the two most attractive clean energy technologies for investment.
- Despite declining attractiveness of the U.S. as a venue for clean energy investment compared to previous years, respondents said they plan to develop and finance more American clean energy projects in 2026 than they did in 2025.
- Policy and investment uncertainty clouds the trajectory post-2026, with the potential for additional roadblocks to financing and developing clean energy infrastructure.
This report complements the Clean Energy Investment Trends report released last month that S&P Global prepared for ACORE.
“ACORE’s recent reports highlight a common thread: the U.S. clean energy sector remains capitalized and ready to help deliver electricity reliability and affordability for American consumers,” said ACORE President and CEO Ray Long. “Our sector is thriving and poised to meet this moment of significant electricity demand growth, but investors and developers need policy certainty to deliver on this critical infrastructure for American energy security.”
ACORE released the report at its annual Finance Forum in New York City today and discussed the takeaways during the opening panel with ACORE Senior Vice President for Policy Lesley Hunter, Avangrid CEO Jose Antonio Miranda, and S&P Global CERA Consulting Director Christopher Wilfong.
Please email communications@acore.org if you’d like to view the recording of the first panel or set up an interview with ACORE about the report. Register here to tune in to the other panels.
ACORE will host a member-only webinar to discuss both reports on May 21, 2026. Learn more about becoming an ACORE member here.

ICE Terrorizing Americans
As shown at left, we still have judges who are fighting to prevent the United States from becoming a fascist nation.
I remain amazed that there aren’t more deaths associated with masked ICE agents attempting to arrest people, especially in their homes. Imagine this:
An American, say John Doe, has a loaded shotgun in his home office closet, where he’s writing blog posts, or whatever.
A masked man, visibly armed, with no warrant for his arrest rings the doorbell and tells his wife who’s answered the door, that he’s there for John.
John overhears the conversation, takes his gun, walks down the hallway, swings around toward the front door, and puts a hole in the intruder’s chest the size of a grapefruit.
Again, I can’t imagine why there isn’t more blood spurting out of the bodies of masked terrorist thugs operating illegally.

Ayn Rand Is No Longer a “Thing” — Here’s Why
A reader asks:
Isn’t it time for the Libertarians to cast aside the whole myth of objectivism championed by Ayn Rand? She said we should be realists, so let’s be real and see her for who she really was … a women who when she got sick, and push came to shove, cashed the checks.
To put this into perspective, Ayn Rand:
Was a considerable “thing” in the mid-20th Century. I was one of millions of young people who read “Atlas Shrugged” and “The Fountainhead,” and accepted libertarianism at the time.
Her way of thinking evaporated, for most of us anyway, when we realized that unbridled greed was eventually going to cause the demise of humankind on this planet.
The actual root cause of this demise was unclear, but as the years passed, environmental collapse became the prime suspect. Rich people obviously couldn’t care less about climate change, ocean acidification, loss of biodiversity, or desertification.
