As AI reshapes the economy, energy isn’t just infrastructure—it’s the constraint, the catalyst, and the investment opportunity.
The world runs on electricity, now more than ever.
As artificial intelligence accelerates across every sector of the economy, a fundamental truth is becoming impossible to ignore: the digital revolution is constrained by something decidedly physical. You cannot build the future without the power to run it.
“Electricity is the new oil.”

“Electricity is the new oil,” says Rob Thummel, Senior Portfolio Manager at Tortoise Capital Advisors. This observation captures a profound shift in how we must think about energy’s role in the modern economy. What was once background infrastructure has become the defining resource—and the primary constraint—of our era.
This article examines four critical dynamics that are repositioning electricity at the center of investment strategy:
- AI’s Industrial-Scale Power Requirements
- The Relentless March of Energy Demand
- Economy-Wide Electrification
- Energy as Geopolitical Leverage
#1 AI’s Industrial-Scale Power Requirements
Behind every generative AI query, every machine learning model training session, every real-time inference operation, there exists a data center consuming electricity at industrial scale. The computational infrastructure powering today’s AI revolution operates continuously, creating base-load demand that differs fundamentally from previous technology cycles.
“It’s becoming increasingly apparent that the data centers are very power hungry,” notes Brian Kessens, Portfolio Manager at Tortoise. The scale is substantial: U.S. data center electricity demand is projected to double over the next five years, with some forecasts suggesting these facilities could consume as much as 8-10% of global electricity within the decade.
This represents a category shift in electricity consumption patterns. AI workloads don’t follow traditional usage curves. They run 24/7/365 and demand reliable base-load power at unprecedented scales. Training a single large language model can consume as much electricity as several hundred homes use in a year. As these models proliferate and grow more sophisticated, the electricity requirement becomes exponential, not linear.
“Data centers are very power hungry.”

The implications extend beyond simple capacity. Data center operators increasingly negotiate directly with utilities and energy providers, effectively functioning as major industrial customers. In some regions, data center demand is outpacing grid expansion capability, creating genuine supply constraints that will take years to resolve. Some data centers have had to become their own power companies, developing full “behind the meter” (BTM) power generation capabilities on site.
#2 The Relentless March of Energy Demand
Context matters in energy markets, and the long-term context tells a definitive story: global energy demand has increased in 40 of the past 42 years. The only interruptions came during the 2008 Global Financial Crisis and the COVID-19 pandemic—both temporary demand shocks followed by resumed growth.
This consistency reveals something essential about energy demand: despite decades of efficiency improvements, despite technological advances that reduce consumption per unit of economic output, aggregate demand continues to rise. The reason is straightforward: economic growth, population expansion, and rising living standards in developing economies consistently outpace efficiency gains.
We are currently experiencing more than typical demand growth. Multiple structural forces—artificial intelligence, industrial reshoring, transportation electrification—are converging simultaneously. Historical data suggests these inflection points are rare and consequential for long-term investment positioning.
The pattern is unmistakable. Energy demand is not cyclical in any meaningful sense. It is structural, persistent, and increasingly tied to the core drivers of economic development in the 21st century.
#3 Economy-Wide Electrification
While AI captures headlines, it represents only one driver in a broader electrification trend reshaping the U.S. (and world) economies. Consider the multitude of convergent forces at work beyond AI:
Industrial Reshoring – Manufacturing capacity returning to the U.S. brings substantial new electrical load. Semiconductor fabrication plants, battery manufacturing facilities, and advanced materials production all require reliable, high-capacity power infrastructure.
Transportation Electrification – The shift from internal combustion to electric vehicles transfers energy demand from refined petroleum to the electrical grid. This transition is only beginning, with significant runway ahead as EV adoption accelerates.
LNG Export Infrastructure – The U.S. has become the world’s largest exporter of Liquefied Natural Gas (LNG). LNG production for global export represents one of the most energy-intensive industrial processes, requiring enormous compression and cooling capacity.
Grid Modernization – The replacement of fossil fuel-based heating and cooling systems with electric alternatives, coupled with the integration of renewable sources, is fundamentally reconfiguring electricity demand profiles.
As Tortoise research observes, every major macroeconomic theme currently in play has an embedded energy demand component. This is not a technology story playing out in isolation. The digital economy, the reshoring imperative, the decarbonization effort, the infrastructure buildout—all of these depend on abundant, reliable electricity.
The investment implications are significant. Energy demand is not coming from a single source that might plateau or reverse. Multiple, independent drivers are creating compounding effects that point toward sustained growth in electricity consumption for years to come.
#4 Energy as Geopolitical Leverage
“It’s a new arms race… and energy is central to who wins.”
— Mark Marifian, Head of Product, Tortoise Capital
Energy has always carried geopolitical weight, but the nature of that leverage is evolving. During the Cold War, nations competed primarily through military capabilities. Today’s competition increasingly centers on technological supremacy, particularly in artificial intelligence—and AI development is fundamentally constrained by energy availability.
“It’s a new arms race… and energy is central to who wins,” says Mark Marifian, Head of Product at Tortoise. The observation is apt. Nations pursuing AI leadership must secure not just computational expertise and semiconductor capacity, but the underlying electricity infrastructure to power continuous, large-scale operations.
This dynamic is reshaping national security calculations. AI capabilities influence defense systems, intelligence operations, cybersecurity, logistics, and economic competitiveness. Countries with reliable access to abundant electricity possess a structural advantage in developing these capabilities. Those without face meaningful constraints.
The competition between the United States and China for AI dominance occurs against this backdrop. Both nations recognize that energy infrastructure—its capacity, reliability, and independence—directly affects their ability to maintain technological leadership. Energy policy is increasingly inseparable from technology policy, which is increasingly inseparable from national security strategy.
For investors, this creates an unusual opportunity set. Energy companies that provide reliable, scalable electricity are no longer simply commodity plays subject to price volatility. They are infrastructure providers enabling strategic capabilities that governments view as essential to national interests.
All of this shifts both the risk profile and the opportunity set in meaningful ways.
Where Will the Power Come From?
The supply question looms large. Renewable energy sources have expanded substantially over time, contributing meaningfully to overall capacity, though their growth trajectory has been shaped by public policy alternating between providing tailwinds or headwinds. Advances in battery storage technology have been critical in making renewables a more complementary part of the energy portfolio, allowing solar and wind generation to extend beyond their natural production windows.
Despite substantial investment in renewable capacity, fossil fuels still provide approximately 80% of global energy—essentially unchanged from five years ago. This persistence reflects not policy failure but physical reality.
“Energy transition? In reality it’s about energy addition,” according to Tortoise Senior Portfolio Manager, James Mick, CFA. Meeting massive, continuous electrical loads at the scale required for modern industrial operations, data centers, and grid stability demands sources that can operate regardless of weather, season, or time of day.

“We think the future supply sources will be natural gas and nuclear,” notes Rob Thummel. Both offer critical characteristics:
- Scalability – Capacity to meet enormous loads as demand grows
- Reliability – Ability to provide 24/7 base-load power without interruption
- Infrastructure Integration – Existing integration with transmission and distribution networks
Natural gas provides flexible capacity that can ramp up or down to meet variable demand. Nuclear offers energy density and zero emissions from continuous operations. Small Modular Reactors (SMR) offer a new approach to localized deployment of nuclear power. Both natural gas and nuclear will be essential components of meeting the electricity demand curve ahead.

This is engineering pragmatism, not ideological positioning. The question is not which energy sources we might prefer in theory, but which ones can actually deliver the power volumes and reliability characteristics that modern economies require in practice.
Investment Implications
Electricity has shifted from a utility function to a strategic constraint. This transition creates investment opportunities that extend well beyond traditional energy sector boundaries.
Energy companies focused on natural gas production, pipeline infrastructure, and utility-scale power generation are no longer simply commodity businesses. They are enablers of digital infrastructure, AI development, industrial reshoring, and national competitiveness. This repositioning affects both valuation frameworks and risk assessment.
For investors seeking exposure to the defining trends of the next decade—AI, industrial policy, geopolitical competition, infrastructure investment—energy companies warrant renewed attention. The sector has transformed its capital discipline and cash flow generation while simultaneously becoming indispensable to the technologies and industries shaping the future.
