For decades, one overlooked domestic energy source remained largely outside the investment conversation. As AI infrastructure, hyperscale data centers, and U.S. electricity demand continue accelerating, investors are beginning to revisit technologies and resources that were previously ignored.
This report explains why that shift may already be underway.

The Drilling Rig That Just Entered the AI Trade

The AI trade was supposed to be about chips. The grid just made it about kilowatts. Data center electricity demand is set to triple by 2030. The U.S. has 3.97 gigawatts of geothermal capacity, and 150 gigawatts of untapped potential sitting under the rock. Oil-field drilling techniques are being repurposed to reach it. The capital is already moving underground.
The Breakdown
Today’s disagreement: the market priced AI compute at 40 times earnings. It priced the power infrastructure to run it at a fraction. One side of that equation has to close.
01
The Demand Spike
Global data-center electricity consumption is projected to surge more than 300 percent by the end of the decade, per the IEA. In the U.S. alone, hyperscalers have announced over $700 billion in data-center capital expenditures. The grid was not built for this. Something has to fill the gap.
02
The Capital Moves Underground
Fervo Energy raised $2.2 billion in May in the largest primary energy IPO in recent memory. Google signed a 3-gigawatt geothermal framework agreement. Meta contracted 150 megawatts of waterless geothermal in New Mexico. The money is moving from chip fabs to drill sites.
03
The Oil-Field Connection
Enhanced geothermal systems use the same horizontal drilling, directional steering, and hydraulic stimulation that built the shale revolution. The toolkit exists. The market just has not priced the connection between a drill rig in Utah and a GPU rack in Virginia.
By the Numbers
Fervo IPO (May 14)$2.2B raised
Google Geothermal Framework3 GW through 2033
U.S. Geothermal Capacity (2024)3.97 GW — 0.4% of generation
EGS National Potential (USGS)150+ GW
Cape Station (Fervo, Utah)100 MW → 4.3 GW potential

The Power Source That Used to Be a Punchline

The Gap Nobody Budgeted For

The AI capital expenditure cycle is measured in hundreds of billions. Microsoft, Google, Amazon, and Meta have collectively committed over $700 billion to data-center buildouts through 2030. Each new facility requires 50 to 200 megawatts of firm, around-the-clock power. The grid was not designed to deliver that on the timeline the hyperscalers need it. Natural gas plants take four to six years to permit and build. Nuclear takes a decade. Solar and wind are intermittent. The firms building the AI infrastructure cannot wait for the grid to catch up.

The Shale Playbook, Applied Underground

In this tape, the capital rotation is not theoretical. Enhanced geothermal systems pump cold water into hot rock miles below the surface, heat it, and return it as steam to drive turbines. The technology uses horizontal drilling, directional steering, and hydraulic stimulation — the exact techniques that built the shale revolution. The DOE’s FORGE project in Utah proved the concept. Drilling rates improved more than 500 percent between 2017 and 2024. Fervo Energy commercialized it, achieving 30 meters per hour, nearly four times what FORGE demonstrated in its early wells.

Fervo’s May 14 IPO on Nasdaq raised $2.2 billion after upsizing the offering three times — the largest primary energy and power IPO in recent memory. The company has 658 megawatts in binding power purchase agreements worth $7.2 billion in contracted revenue. Its Cape Station in Utah, the world’s largest enhanced geothermal project, is commissioning its first 100-megawatt phase this quarter with 4.3 gigawatts of total resource potential at the site.

Where the Hyperscaler Money Is Going

Our view: the market is pricing AI as a semiconductor trade. The hyperscalers are pricing it as an energy trade. Google signed a 3-gigawatt geothermal framework agreement with Fervo, enough to power roughly 2.4 million homes. Ormat Technologies and NV Energy signed a 150-megawatt PPA in February specifically for Google data centers in Nevada. Meta contracted 150 megawatts of waterless geothermal with XGS Energy in New Mexico. These are not pilot programs. These are long-duration, binding infrastructure commitments from the same firms spending hundreds of billions on GPU clusters.

The cost curve supports the thesis. Wood Mackenzie estimated Fervo’s Cape Station can produce electricity at $79 per megawatt-hour without subsidies. New nuclear runs $142 to $222 per MWh. The U.S. Geological Survey estimates 150-plus gigawatts of EGS resource potential nationally. Current installed geothermal capacity is 3.97 gigawatts. The ratio between what exists and what is possible is 38 to 1.

What to Watch This Week

Worth watching: JOLTS data lands tomorrow. Jobs Friday closes the week. Both readings feed the macro environment that either supports or compresses the AI capex cycle. If hiring decelerates in construction and manufacturing, the buildout timeline stretches and the power gap widens. If it holds, the infrastructure trade accelerates. Either way, the capital allocation decision has already been made at the hyperscaler level. The question for the portfolio is whether the market prices the power side at the same conviction it priced the compute side — or whether the gap stays open long enough to become the trade.

The oil industry spent a century learning how to drill. The AI industry just learned it needs every rig.
