Far below the forests of central Oregon, a powerful new kind of clean energy is being developed. At the Newberry Volcano, a company called Mazama Energy is drilling nearly two miles underground into superheated rock. Their goal is to tap into steady heat from the Earth to create renewable electricity that’s available all the time. This project is among the most advanced geothermal efforts in the country and could mark a new chapter in how the U.S. produces clean energy that doesn’t depend on weather.
Across the nation, the demand for electricity is growing fast. Data centers, electric vehicles, artificial intelligence, and a strong economy are all increasing the strain on power grids. Traditional renewable sources like solar and wind energy are vital, but they depend on sunshine and wind conditions, which can change daily. To keep electricity flowing 24 hours a day, utilities need power sources that can run constantly.
Geothermal energy offers this kind of reliability. It captures heat from deep inside the Earth and converts it into power. While solar panels rest at night and wind turbines stop on calm days, geothermal plants can keep producing electricity around the clock. The challenge is that natural geothermal systems, where hot water and steam are already close to the surface, exist only in certain regions. Enhanced geothermal systems, like the one being tested at Newberry, aim to overcome this by creating artificial underground reservoirs that store and circulate heat even in dry rock formations.
Building Energy Beneath a Volcano
Newberry Volcano, located in the Cascade Range of Oregon, has fascinated scientists for decades. Its last eruption happened around 1,300 years ago, leaving behind black volcanic glass and wide lava fields. Beneath that surface lies an enormous source of heat. Researchers and companies have studied the area for years, making it an ideal place to test new geothermal technologies.
In recent years, Mazama Energy has used improved drilling tools and high-temperature materials to dig deeper than any previous project there. The team reached depths of about two miles underground, accessing some of the hottest rock ever measured in a U.S. geothermal site. By carefully cracking certain layers of rock, they created small spaces where water can circulate, absorb heat, and return to the surface, forming what is known as an enhanced geothermal system.
If it performs as planned, this underground heat source could produce enough power for thousands of homes. To get there, Mazama will need to drill additional wells, build surface equipment, and connect to the electric grid. One key advantage is that superhot geothermal systems can generate much more energy from each well compared to traditional geothermal plants. This makes them an exciting option for providing steady, dense, and renewable electricity.
Protecting Nature and Local Communities
The Newberry project sits inside Oregon’s Deschutes National Forest, near the well-known Newberry National Volcanic Monument. The area attracts campers, hikers, and scientists who come to see its lakes, lava fields, and forests. Because of this, Mazama Energy has taken steps to reduce the project’s environmental impact by locating all main facilities outside the monument boundaries.
Beyond environmental protection, the project also offers economic and educational benefits. It can create jobs in drilling, engineering, and energy operations, while also supporting local businesses. Schools and universities have joined in to train future geothermal experts, building skills for other clean energy projects in the region.
Still, some challenges remain. Since Newberry is an active volcano, the project must pass strict safety and environmental reviews. Government agencies monitor land use, wildlife, cultural resources, and water quality. Scientists also watch for small earthquakes and check how the drilling affects underground water systems.
Mazama’s system is designed as a closed loop that recycles water instead of consuming large volumes. This means far less water use compared to older geothermal methods. Even so, some residents worry about possible effects on groundwater, seismic activity, and the landscape. The developers have responded by holding community meetings, releasing regular reports, and partnering with universities to study and reduce any potential risks.
A Glimpse of the Future of Clean Energy
Around the world, countries like Iceland, Kenya, and Indonesia have long produced geothermal electricity, but they mainly rely on natural reservoirs filled with steam or water. The work at Newberry is different, it uses technology to engineer an artificial reservoir in hot, dry rock. Only a few sites worldwide have tried this approach, and Newberry is one of the most advanced efforts so far.
Turning this demonstration into a commercial power plant, however, is a big challenge. The team must prove the underground reservoir can stay hot and maintain its flow for years without environmental harm. They also need more wells, testing equipment, power contracts, and government approval before they can deliver energy to the grid.
Even with these hurdles, the success of Newberry could mark a turning point for clean energy. By showing that superhot geothermal systems work, the project may open the door to consistent, weather-independent power on a national scale. If it succeeds, it could reshape the way the United States, and perhaps the world, thinks about renewable electricity.
