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.

Explaining Our Role in the Universe to Young People
At left, we have the words of American planetary scientist Dr. Carolyn Porco, who explores the outer Solar System, beginning with her imaging work on the Voyager missions to Jupiter, Saturn, Uranus and Neptune in the 1980s.
FWIW, I don’t take the same tack. As a guy who’s done his fair share of tutoring young people in science, and who has also raised two kids, I’ve had to deal with the issue a great many times.
When someone wants me to tell them what happens when we die, I ask, “Do you want to know what scientists have learned about the universe as it applies here, or what the believers in an all-powerful God think? I’m happy to explain the ideas of both of of them.”
Normally, at this point, the kid (understandably) wants to change the subject, which is just fine with me.

Killing EV Tax Credits Will Hurt American Workers
The global auto market grew by 25% in 2024, and nearly one in five cars sold globally is now electric. A record 1.3 million EVs were sold in the US, a 7.3% year-over-year increase that outperformed the 2% increase in nationwide sales of gas vehicles. Automakers are offering an increasing number of EV models to compete in this rapidly expanding global marketplace.
To ensure that American workers benefit from this global growth, Congress should preserve existing EV manufacturing and consumer tax credits and ensure that automakers build these EVs and batteries in the US. These credits have already unleashed over $215 billion in announced private-sector EV and battery investments and created 238,000 jobs.
If you think this economic boom doesn’t apply to the Southeast, think again. Over the past two years, the Southeast has emerged as the nation’s leading EV and battery manufacturing region, accounting for 38% of the nation’s investments and 31% of anticipated jobs. These investments deliver economic development and employment, especially to our region’s rural communities.
- Topping the list of rural economic development is Toyota’s $13.9 billion battery manufacturing facility in Randolph County, North Carolina. The facility is expected to create 5,100 jobs and is the nation’s highest clean energy investment.
- Hyundai has made the second-largest regional investment at its battery manufacturing and EV assembly plant in Bryan County, Georgia. That investment tops $6 billion and is expected to create 3,400 jobs. It has had a massive ripple effect, with Hyundai suppliers announcing more than $2.7 billion in investments and an anticipated 6,900 jobs across the state.

Manufacturing and Consumer Tax Credits Work Together
The manufacturing and consumer tax credits were designed to complement one another by expanding domestic EV and battery manufacturing, creating American jobs, securing domestic supply chains, and encouraging EV adoption.
Eliminating either the manufacturing or consumer incentives will undermine these goals.
Manufacturing tax credit incentivizes companies to expand and relocate operations in the US, securing domestic supply chains and creating American jobs. Consumer tax credits provide up to $7,500 for new and $4,000 for used EVs and help consumers and fleet operators switch to EVs. The critical hitch is this: Consumer credits are only good on EVs that meet domestic critical mineral, battery, and assembly requirements. This further incentivizes automakers and battery producers — both American and foreign — to build manufacturing capacity here in the United States.
Eliminating the manufacturing tax credit will create uncertainty and chill private sector investments in our region and nationwide. Similarly, if the consumer tax credit is eliminated, incentives for automakers to assemble EVs and source batteries in America, by American workers, will disappear.
Researchers from Princeton University’s REPEAT Project recently determined that without the consumer EV tax credit, “EV sales in the US could decrease 30% by 2027 and nearly 40% by 2030. Such a slowdown could lead to 100% of planned expansions of US EV assembly plants being canceled, and could make 29% to 72% of US battery-manufacturing capacity redundant, according to the study. Factories that are idled—or never built in the first place—mean fewer jobs. And based on the distribution of current EV-related manufacturing projects, red states could be hit the hardest.”
In the Southeast, Representative Buddy Carter in GA’s 1st District supports maintaining EV and battery manufacturing momentum. Hyundai’s plant is located in his district. Use the button below to tell Rep. Carter to keep fighting for advanced auto manufacturing jobs in Georgia and beyond.
Meanwhile, Chinese brands, which account for half of all EVs sold globally and 80% of the world’s lithium-ion battery production, would be thrilled to see the end of America’s EV and battery manufacturing renaissance.
Congress, particularly Republican senators and representatives from districts with investments and jobs at stake, must understand that eliminating the tax credits will weaken domestic EV and battery production and the domestic EV market, thereby delivering the global EV market to Chinese automakers and battery producers, and undercutting American workers and undermining America’s supply chain security.
Congress should prioritize strengthening the American auto sector’s ability to compete globally, securing America’s supply chains, and protecting American jobs. Federal tax credits are helping us catch up in the international EV race by incentivizing American automakers to expand EV manufacturing and global auto and battery manufacturers to invest in America. Killing the tax credits will all but ensure that Chinese companies win and American workers, including nearly 74,000 in the Southeast, lose.
