    AI is bringing an unprecedented surge in energy consumption, whether policymakers understand the energy implications or not.

    In the realm of artificial intelligence (AI), where data crunching and machine-learning algorithms reign supreme, the demand for energy has
    emerged as a critical concern. Mark P. Mills, the executive director of
    the National Center for Energy Analytics (an initiative I oversee at the
    Texas Public Policy Foundation), argues that the energy requirements for
    AI systems are far more substantial than most of us know. His insights
    paint a sobering picture of the energy landscape that awaits us as AI
    continues its relentless advance into every facet of modern life.

    Mills contends that the computational intensity of AI applications, such
    as deep learning and real-time data processing, is driving an
    unprecedented surge in energy consumption. According to the International Energy Agency, the global electricity consumption by AI alone could reach
    1,000 terawatt-hours (TWh) annually by 2026, slightly more than the total electricity consumption of Japan. The appetite will be formidable as it
    becomes integral to industries ranging from health care to finance, and transportation to agriculture.

    At the heart of the debate lies a fundamental question: Can renewable
    energy sources adequately power the AI revolution? Silicon Valley, home to
    tech giants like Google, Facebook, and Tesla, has been a vocal advocate
    for renewable energy solutions. Many of these companies have committed to ambitious sustainability goals, including achieving carbon neutrality or
    even operating entirely on renewable energy. Most of these promises are
    hollow, at best, in that they rely on periodic renewable energy contracts
    to make the claim that they’re 100 percent renewable while connected to a
    grid stabilized and made reliable largely by traditional dispatchable
    thermal power — nuclear, natural gas, and even coal.

    California is the nation’s test case for renewables. It’s the state with
    the most aggressive greenhouse gas reduction agenda. I voted against AB
    32, the “California Global Warming Solutions Act of 2006,” which kicked
    off this effort. Back then, California’s electricity prices were the
    eighth most expensive in the nation and 44 percent above the national
    average. Today, after installing all that “cheap” solar and wind energy, California’s electricity prices are the second most expensive in the
    United States, trailing only Hawaii, with consumers paying almost double
    the national average.

    Yet, while a grid dominated by renewables isn’t affordable, it’s also not reliable. Mills argues that though renewable sources like solar and wind
    have made significant strides, they face inherent limitations in meeting
    the continuous and predictable energy demands of AI systems.

    The reality is stark: AI operations require uninterrupted power to
    function optimally. Unlike conventional electricity generation, where
    output can be adjusted to meet fluctuating demand, renewable sources
    depend on weather conditions and geographic location. This intermittency
    poses challenges for maintaining the stability and reliability of the
    power supply necessary for AI’s computational tasks, which often operate
    around the clock. The same can be said of chip fabrication as well as
    other industrial processes.

    Moreover, the infrastructure needed to support AI’s energy demands goes
    beyond generating capacity. Mills points out that the transmission and
    storage of electricity — key components in ensuring a reliable energy
    supply — are critical bottlenecks that must be addressed to accommodate
    AI’s voracious appetite for power. Without substantial advancements in
    grid technology and energy storage solutions, the scalability of renewable energy in meeting AI’s needs remains a mirage — an expensive mirage.

    A promising solution lies in the adoption of modular nuclear reactors and nuclear power in general. These technologies offer the continuous and
    reliable energy necessary for AI operations, providing a stable base load
    that complements intermittent renewable sources. Nuclear power, with its
    low carbon emissions and high energy density, is uniquely positioned to
    support the energy-intensive demands of AI.

    Unfortunately, the regulatory process for permitting new nuclear power
    plants resembles a plate of spaghetti, with environmental lawsuits as the
    sauce on top. Only two new nuclear reactors have come online in the United States in the past three decades — Vogtle Units 3 and 4, which connected
    to the grid in July 2023 and April 2024 and “produce enough electricity to power 1 million homes.” China, on the other hand, has 55 nuclear reactors
    with 23 under construction, while India has more than 20 with seven more
    under construction. Rather than reduce the red tape, Congress has sought
    to pour subsidies on the problem — meaning that if nuclear power does get
    built here, it will take too long and cost too much.

    Silicon Valley’s techno-optimism — and business plans — must be fueled by reliable power. But green tech advocates remain steadfast in their belief
    that renewables can and should power the AI future. However, the gap
    between aspiration and practicality is widening, sparking interesting
    political frictions in what used to be a close alliance.

    The political and policy implications of this debate are profound. Germany
    is a cautionary example of a nation that grappled with decarbonization
    goals and commitments under the Paris Agreement, voluntarily starting the process of deindustrialization in service of green goals — something
    envisioned by the Morgenthau Plan in the aftermath of World War II as a punishment and a means of preventing the Germans from having the capacity
    to start another world war. Now Germany is faced with making a costly volte-face on energy if it is to avoid being entirely dependent on China,
    much less even try to participate in the AI space.

    Furthermore, the economic dimensions of AI’s energy demands cannot be overlooked. Mills warns that overlooking the scale of energy consumption
    by AI could lead to supply constraints and price volatility in global
    energy markets. For industries reliant on AI technologies — from
    autonomous vehicles to smart grids — ensuring stable and affordable energy sources is essential for long-term viability and growth.

    AI is coming, whether policymakers understand the energy implications or
    not. Since politicians aren’t likely to move fast enough, the fascinating
    thing to watch will be the necessity-driven transformation of Silicon
    Valley into a major energy-producing powerhouse.
