Status Of Geothermal In USA , 2025

Abstract

By:Robert Buluma

Geothermal energy, a renewable and sustainable resource, plays a modest yet significant role in the United States' energy landscape. As of 2023, the U.S. leads globally with an installed geothermal capacity of approximately 3,900 megawatts (MW), accounting for about 25% of the world's total geothermal capacity.  This article provides a state-by-state overview of geothermal energy production, highlighting the contributions of key states and recent advancements in the sector.

Introduction

Geothermal energy harnesses heat from the Earth's interior to generate electricity and provide heating solutions. Its consistent output and low environmental impact make it a valuable component of the renewable energy mix. In the United States, geothermal resources are predominantly located in the western states and Hawaii, where geological conditions are favorable.

The Billion-Dollar Gamble Beneath Our Feet: Why Geothermal Exploration Is the Industry’s Greatest Risk

Exploration Risk: The Billion-Dollar Gamble Beneath Our Feet By:  Robert Buluma Image credit: Kane Watikson on LinkedIn  Geothermal energy is often described as the sleeping giant of the clean energy transition  constant, weather-independent, capable of delivering 24/7 baseload power without the intermittency that defines solar and wind. Yet despite this extraordinary promise, geothermal remains underdeveloped in most parts of the world. The reason is not lack of heat. It is not lack of demand. It is not even lack of technology and not even  FINANCE ,  Whilst many will throw that policy card, but Alphaxioms is already future proofing that .  The real barrier lies several kilometers beneath our feet  in uncertainty. Exploration risk is the defining challenge of geothermal energy. Unlike wind turbines that can measure wind speeds before construction, or solar farms that can predict output from sunlight data, geothermal developers must make multimillion-d...

7,000 Feet Deep, 338°F: The Game-Changing Sensor Revolutionizing Enhanced Geothermal Systems

Breakthrough in Geothermal Monitoring: Berkeley Lab's High-Temperature Seismometer Powers the Future of Enhanced Geothermal Systems By: Robert Buluma Image: Cape Station, Fervo Owned Geothermal Station  Geothermal energy has long been valued as a reliable, clean, and renewable source of power. It draws heat from deep within the Earth to generate electricity with virtually no greenhouse gas emissions during operation. Traditional geothermal plants rely on naturally occurring hot water or steam reservoirs, which restricts development to specific volcanic or tectonically active regions. Enhanced Geothermal Systems (EGS), however, represent a game-changing evolution. EGS engineers artificial reservoirs in hot, otherwise impermeable rock formations found almost anywhere with sufficient subsurface heat. By injecting fluid under pressure to create and propagate fractures, EGS dramatically expands the geographic reach and scalability of geothermal power, offering the potential for 24/7, c...
