Explore Geothermal Energy Jobs

Geothermal energy offers something wind and solar cannot: 24/7 baseload power with a capacity factor that routinely exceeds 90%. But it also imposes a constraint the other renewables do not — you cannot build it just anywhere. Your career in geothermal will be shaped less by the technology you work with than by the geology beneath your feet. Iceland, Turkey's Aegean coast, Kenya's Rift Valley, Indonesia's volcanic islands, Italy's Tuscany region — these are not

arbitrary job markets. They are the places where Earth's interior heat is close enough to the surface to extract economically. For anyone considering this sector, the first question is not "What role do I want?" It is "Where am I willing to go?"

Globally, geothermal employed approximately 160,000 people in 2024 across power generation, district heating, and ground-source heat pump installation. That number is modest compared to solar's 7.3 million or wind's 1.9 million, but it is about to change. The IEA projects that geothermal employment could rise sixfold to 1 million jobs by 2030, driven by Enhanced Geothermal Systems (EGS) and closed-loop technologies that are breaking geothermal free from its volcanic cage. The skills shortage is already visible: 24,000 new jobs in Germany alone if the country hits its 2030 target of 10 TWh/year from geothermal. The Netherlands expects 39,000 to 72,000 jobs by 2030 as it scales district heating for greenhouse horticulture.

Where geothermal works — and why it matters for your career

High-temperature geothermal resources cluster along tectonic plate boundaries. Iceland sits on the Mid-Atlantic Ridge, where diverging plates allow magma to reach within a few kilometres of the surface. Indonesia has 127 active volcanoes and holds roughly 40% of the world's geothermal resources. Kenya's Olkaria complex taps heat from the East African Rift. Turkey's Kizildere plants draw from the Aegean volcanic arc. Italy's Larderello field — the world's oldest geothermal power station, operational since 1904 — sits in Tuscany where the African and Eurasian plates create volcanic intrusions.

This is not just geology trivia. It defines the job market. If you want to work on conventional hydrothermal power plants, you will be looking at positions in Indonesia, the Philippines, Turkey, Kenya, New Zealand, Iceland, Italy, or the western United States. For district heating roles, add Germany, the Netherlands, and Denmark. For heat pump installation, the market is broader but still concentrated in northern Europe and parts of North America.

The geographic lock is loosening. Enhanced Geothermal Systems create artificial reservoirs in hot dry rock, enabling deployment in sedimentary basins that lack natural hydrothermal resources. Fervo Energy's Utah project will deliver 320 MW to Southern California Edison starting in 2026, built on oil and gas drilling techniques adapted for geothermal. Eavor's closed-loop system in Bavaria sent its first commercial power to the grid in December 2025, drilling 4.5 kilometres deep without requiring a natural aquifer. These next-generation technologies accounted for 53% of new geothermal power purchase agreements between 2021 and 2024 and have attracted over $1.5 billion in private investment since 2021.

For job seekers, this means two parallel markets are emerging: the established hydrothermal sector concentrated in volcanic regions, and an expanding EGS/closed-loop sector that will create opportunities in places like Germany, France, the UK, and parts of the United States currently underserved by conventional geothermal.

Technology types — what they mean for the work

Geothermal is not one technology. It is at least four, and they create very different workplaces.

Power generation: dry steam, flash steam, and binary cycle plants

Dry steam plants are the oldest and simplest. Larderello and California's Geysers pull steam directly from the ground and route it to turbines. These are rare — you need naturally occurring steam, not just hot water. Working at a dry steam plant means managing turbine operations, steam condensers, and cooling towers, much like a conventional thermal power station but with geothermal brine chemistry to manage.

Flash steam plants are the most common globally. They pump high-pressure hot water (above 182°C) from deep wells and "flash" it into steam by dropping the pressure. Kenya's Olkaria complex, Indonesia's Salak field, and most of the Philippines' geothermal capacity use this technology. Flash plant operators monitor well pressures, separator vessels, turbine-generator sets, and reinjection systems. The work involves troubleshooting corrosion from geothermal brine, managing scaling in pipes, and coordinating with drilling teams when well productivity declines.

Binary cycle plants can use lower-temperature resources (below 180°C) and are becoming the dominant technology for new installations. They run a closed loop: geothermal fluid heats a secondary working fluid (often an organic compound with a low boiling point) via a heat exchanger, the secondary fluid drives the turbine, and the geothermal fluid is reinjected without ever touching the turbine. Most future geothermal plants will be binary. Operating a binary plant requires understanding both sides of the heat exchanger, managing ORC (Organic Rankine Cycle) turbines, and optimizing for lower-temperature resources. Turboden and Exergy International are the leading ORC equipment suppliers, and knowing their systems is valuable.

Enhanced Geothermal Systems (EGS)

EGS uses hydraulic and thermal stimulation to fracture hot rock and create permeability where none exists naturally. It is geothermal's fracking moment — adapting oil and gas techniques for renewable energy. Fervo Energy employs horizontal drilling, distributed fibre optic sensing, and multi-stage well stimulation borrowed directly from shale gas. Their 3.5 MW pilot in Nevada powers Google data centres and achieved a 70% reduction in drilling time using techniques refined in the Permian Basin.

For workers, EGS means exposure to advanced drilling operations, reservoir engineering, and real-time data analytics. If you have worked in unconventional oil and gas, your skills — directional drilling, hydraulic fracturing, downhole instrumentation — transfer almost directly. The equipment is familiar: mud pumps, coiled tubing, blowout preventers. The difference is scale (fewer wells), temperature (300°C+ rather than 150°C), and regulatory environment (renewable energy incentives rather than fossil fuel economics).

Direct use and district heating

Direct use extracts heat for buildings, industry, agriculture, or district heating networks without generating electricity. Iceland provides 97.4% of its heat demand from geothermal, piping hot water from power plants directly to Reykjavik's homes. Innargi is building large geothermal district heating systems in Denmark, including a 39,000-customer network for Greater Copenhagen. Germany's Stadtwerke München is targeting 560,000 households with geothermal heating by 2040.

District heating roles involve managing pipe networks, heat exchangers, and customer connections rather than turbines and generators. You are operating infrastructure similar to municipal water systems but carrying 60-90°C water across kilometres. Maintenance techs inspect pipelines, diagnose leaks, and manage seasonal load variations. The work is less remote than power plant operations — district heating serves cities — but requires deep knowledge of hydraulic systems, heat pump integration, and urban infrastructure.

Ground-source heat pumps: the semantic confusion

Ground-source heat pumps (GSHP) are called "geothermal" in North America but work on a completely different principle. They circulate fluid through shallow loops (1 to 200 metres) to extract low-grade solar heat stored in the ground, then use a heat pump to upgrade it for space heating. This is NOT the same as deep geothermal. A GSHP installer digs trenches, lays pipe, connects heat pumps, and sizes systems for individual buildings. It is closer to HVAC work than to geothermal engineering. Pay is lower — €2,000-€3,500/month in the Netherlands, $78,000/year in the US — but the market is vast and grows with every building electrification mandate.

For this article, when we refer to "geothermal jobs," we mean deep geothermal: power generation, district heating, reservoir engineering, and drilling. Heat pump installers are a separate (and much larger) workforce.

The numbers: a small sector with big growth ahead

IRENA reports 160,000 geothermal jobs globally as of 2024, though the count depends on what you include. Power generation and district heating employ roughly 91,500 people directly, with indirect jobs pushing the total higher.

Indonesia is the largest single employer, with 5,200 direct professional workers and roughly 870,000 indirect jobs across the supply chain — a high multiplier driven by the country's ambition to become the world's largest geothermal producer by 2030. The United States has approximately 8,870 geothermal employees, concentrated in California and Nevada. Iceland's energy sector anticipates 20,000-25,000 new job openings over the next decade, many in geothermal, as the country expands renewable energy exports.

Europe presents the clearest near-term growth signal. Italy could create over 30,000 jobs with further development — Enel plans €3 billion in investment for two new 100 MW plants by 2030. The Netherlands projects 39,000 to 72,000 jobs by 2030 as it scales geothermal for greenhouse heating. Germany needs 24,000 workers if it hits its 10 TWh target.

The job creation multiplier varies by project phase. During construction, each megawatt of installed capacity creates 26-34 jobs (direct construction, equipment manufacturing, and indirect roles). Once operational, a geothermal plant sustains 1.17 to 1.7 permanent jobs per MW for 30 to 50 years — longer than wind or solar. Geothermal's employment density per megawatt is higher than wind (19 jobs/MW) or solar (12 jobs/MW) when you account for the full project lifecycle.

What the work actually involves: remote, rotational, and physically demanding

Before listing roles and salaries, it is worth stating plainly: many geothermal jobs are hard. Not hard intellectually — though reservoir modelling and drilling engineering require serious technical skill — but hard in the sense of physical discomfort, isolation, and lifestyle disruption.

Geothermal sites sit where geology dictates. Indonesia's 127 active volcanoes are often in mountainous jungle. Kenya's Olkaria is at high altitude in the Rift Valley. Iceland's geothermal fields are in volcanic zones that can be snowed in for months. Turkey's frontier EGS projects are testing wells in remote eastern provinces. These are not commuter jobs.

Field roles typically operate on rotation schedules: 15 days on/5 days off, or 14 on/7 off, with 12-hour shifts during rotations. One job posting for a drilling engineer in Utah required 75-100% travel. Housing is usually provided on-site or nearby, but you are away from home for weeks at a time. Employers attract workers to these locations with competitive salaries, relocation packages, extended vacation policies, and flexible scheduling, but the lifestyle is not for everyone.

The physical environment is demanding. Technicians work outdoors in all weather conditions, exposed to extreme temperatures. Drilling sites involve hazardous conditions: high-pressure wells, caustic geothermal brine, hydrogen sulfide gas, and heavy machinery. Safety equipment is mandatory — helmets, gloves, hearing protection, respirators. Manual labour is routine: digging trenches, lifting equipment up to 60 pounds, operating excavators, crawling through tight spaces.

Office-based roles — reservoir engineers modelling subsurface flow, project developers negotiating land leases, electrical engineers designing grid connections — avoid most of the fieldwork but still require site visits. Even the best-paid engineering positions involve time in remote locations, often under tight project deadlines.

If you want stable, predictable, urban-based work, geothermal may not suit you. If you are comfortable with rotation schedules, frontier conditions, and the kind of problem-solving that happens when equipment fails at 2 AM in a muddy drill yard 200 kilometres from the nearest city, this sector has a place for you — and will pay well for it.

Roles by subsector

Geothermal power generation

Geothermal plant operators run day-to-day operations: monitoring turbines, adjusting well flow rates, recording data, performing routine maintenance. You are watching SCADA screens, inspecting equipment, responding to alarms, and coordinating with maintenance teams. Shifts are typically 12 hours, and schedules can change with production demands. In Iceland, operators earn ISK 12.9 million/year (roughly €85,000). In the US, geothermal production managers average $75,500/year, though California roles reach $160,000-$250,000 for senior positions.

Geothermal engineers design systems, optimise plant performance, and troubleshoot problems. In Germany, they earn €80,600/year. New Zealand pays NZD $102,500 (€59,000). The US market varies widely: ZipRecruiter reports $91,000 nationally, while Glassdoor shows $145,000, reflecting California's premium.

Reservoir engineers model subsurface fluid flow, predict well productivity, and plan drilling campaigns. This is the most analytically intensive role, requiring strong skills in thermodynamics, fluid mechanics, and numerical modelling. The US pays $124,000/year on average, with top earners exceeding $166,000. Germany offers €95,400 for petroleum reservoir engineers — the closest proxy for geothermal. The Netherlands averages €74,000.

Project managers oversee development from permitting through commissioning. They coordinate drilling contractors, equipment suppliers, environmental consultants, and grid operators while managing multi-million-euro budgets over 3-7 year timelines. Iceland pays ISK 856,000/year (general project managers). US geothermal project managers earn $92,000/year on average, with California roles commanding $160,000-$250,000.

Drilling and well services

Drilling engineers plan well trajectories, select drill bits, manage mud programs, and supervise drilling operations. Geothermal wells can exceed 3,000 metres in depth and encounter temperatures above 300°C, requiring specialised equipment and expertise. The work involves long shifts on-site during drilling campaigns, often in remote locations. New Zealand pays NZD $102,500 (geothermal engineer proxy). The US offers $109,400/year. Kenya, where KenGen is expanding Olkaria, pays drilling engineers KES 120,000-180,000/month (€750-1,125), with senior roles reaching KES 210,000.

Drillers and rig operators run the equipment: operating drawworks, managing casing and cementing, and troubleshooting mechanical failures. This is hands-on, shift-based work with significant physical demands and safety risks. It is also where oil and gas workers transition most easily — the rigs, the procedures, and the language are nearly identical.

Geologists and geophysicists

Exploration geologists identify prospective geothermal resources using surface surveys, geochemical sampling, and geological mapping. Reservoir geologists interpret well data, map fracture networks, and build subsurface models. Iceland pays geologists ISK 14.1 million/year and geophysicists ISK 15.9 million. Italy offers €78,300/year for geophysicists. Turkey pays 1.31 million TRY/year (€42,000) in Istanbul. The US averages $118,500 for geophysicists, though geothermal-specific geologist roles can be closer to $61,400.

District heating and direct use

District heating operators manage pipe networks that carry geothermal water from source wells to end users. They monitor flow rates, temperatures, and pressures; respond to leaks; and coordinate maintenance. In Germany, heating workers earn €51,900/year. The Netherlands pays HVAC technicians (a reasonable proxy) €55,900/year.

District heating project developers secure permits, negotiate with municipalities and property owners, arrange financing, and manage construction of new networks. Companies like Innargi in Denmark and Stadtwerke München in Germany are actively expanding their teams as they scale geothermal district heating.

Heat pump installation

Ground-source heat pump installers dig trenches, lay pipe loops, connect heat pump units, and commission systems. The work is physical and weather-exposed but less remote than drilling or power plant operations. The Netherlands pays €2,000-€3,500/month gross (€24,000-€42,000/year), with experienced technicians and freelancers earning more. Germany offers €3,367/month median (€40,400/year), with master technicians (Meister) reaching €55,000-€70,000. The US averages $78,000/year nationally, with San Jose paying $78,500 — 97% above the US average.

Skills transfer from other industries

The closest adjacent sector is oil and gas drilling. Directional drilling, well construction, cementing, drilling fluids, downhole tools, reservoir management, and rig operations all transfer nearly 1:1. Fervo Energy's leadership includes veterans from Halliburton and BHP. If you have worked on a drilling rig in the Permian Basin or the North Sea, you can work on a geothermal rig in Iceland or Indonesia with minimal retraining — the main differences are higher temperatures, longer well lifetimes, and reinjection rather than production decline curves.

HVAC technicians transition into heat pump installation and binary cycle plant operation. Understanding heat exchangers, fluid loops, and thermodynamics gives you most of what you need. The step from installing residential air conditioning to commissioning a binary cycle ORC turbine is larger, but the fundamentals are shared.

Civil engineers fit naturally into district heating project development, geothermal field infrastructure, and well pad construction. Permitting, environmental compliance, and site planning require the same skill set whether you are building a highway or a geothermal plant.

Mining professionals — especially hard rock drillers — understand the challenges of working underground in difficult conditions. EGS and supercritical geothermal projects drilling to 4-10 km depths in hard crystalline rock overlap significantly with deep mining operations.

Salary snapshot

Salary data from SalaryExpert, Glassdoor, ZipRecruiter, and ERI. Figures represent mid-range estimates; actual pay varies by experience, location, and employer. Kenyan figures in KES (Kenyan Shilling) converted at ~160 KES = €1. US figures show national averages; California premiums can add 40-100%.

Geothermal consistently pays above average for renewable energy roles, reflecting the technical complexity, remote locations, and relatively small talent pool.

Final consideration: the 24/7 constraint and what it means for your life

Geothermal plants do not shut down. Unlike solar farms that go dark at night or wind turbines that idle when the air is still, geothermal delivers baseload power around the clock. That is its commercial advantage — utilities pay premium rates for reliable capacity — but it also defines the work rhythm. Power plants run continuous operations with rotating shifts. Drilling campaigns operate 24/7 once the rig is mobilised. District heating systems must respond to demand spikes on cold mornings regardless of the calendar.

If you want to work Monday to Friday, 9 to 5, from a fixed office, geothermal offers those roles — project developers, permitting specialists, financial analysts, sustainability consultants. But the core of the industry — the roles that pay the most and offer the fastest career progression — involve fieldwork, shift work, and time away from home. That is the trade. The compensation is real, the skills are valuable and transferable, and the sector is about to scale dramatically. But it will ask you to go where the heat is, and to stay there while the work gets done.

The jobs are out there. The question is whether you are willing to meet geothermal on its own terms.
