Until recently, data centers received little public attention despite their widespread use. That changed with the surge of artificial intelligence (AI), which triggered an unprecedented demand for electricity. Now, just a year into this energy-intensive boom, data centers are raising concerns about the viability of the global shift to renewable energy.
According to a Reuters report, power utilities, regulators, and climate activists are increasingly alarmed by the rapid rise in electricity demand driven by data centers. The unexpected spike has revealed the limits of scaling up renewable energy sources like wind and solar. Experts acknowledge that no amount of renewable capacity—given its intermittent nature—could meet this sudden, round-the-clock demand.
Renewables Struggle to Meet the Demand
The situation is worrying climate advocates. A Washington Post article highlights how the expansion of data centers threatens decades of progress in reducing greenhouse gas emissions. Utilities, in response to soaring energy needs, are planning new gas-fired power plants, raising concerns about increased reliance on fossil fuels.
The main challenge lies in data centers’ need for reliable, continuous electricity. Neither wind nor solar energy, even with battery storage, can guarantee the consistency these centers require. This has pushed many operators to turn to more dependable sources like natural gas, coal, and even nuclear energy, further complicating the global energy transition.
The Role of Natural Gas
For natural gas producers, the surge in demand is a welcome opportunity after years of low prices. Data centers, especially those supporting AI development, require significantly more power, making natural gas the most accessible and immediate solution.
An S&P Global report estimates that data center growth could add between 3 billion and 6 billion cubic feet of daily natural gas demand in the U.S. by 2030. Analysts at the agency predict electricity demand from data centers will rise at an annual rate of 12% over the next six years. From the perspective of natural gas producers, this represents a significant market opportunity.
Pressure to “Green-Up”
Despite the growing dependence on natural gas, data center operators are under increasing pressure to adopt more renewable energy. Speaking to Reuters, Meta spokesperson Jim Cullinan said, “Everyone agrees that we need more and more renewable energy to keep up with a growing demand.” However, Cullinan shifted responsibility to utilities, noting it was up to them to ensure adequate supply.
This response reflects the broader challenge: renewables can supplement energy needs during certain times, but they cannot replace the consistent, 24/7 power provided by baseload generation facilities like gas, coal, or nuclear plants.
A Preview of the Energy Transition
The issues surrounding data centers offer a glimpse into the challenges of the broader energy transition, which relies on total electrification. Experts warn that if initial responses to rising demand involve building more gas and nuclear plants, the transition could create an energy system that may not align with net-zero goals.
“Data centers are just a warm-up act compared to the level of electrification we’re going to need,” the CEO of energy advocacy group RMI told Reuters. “If we default to gas and nuclear, we risk building an energy system we cannot sustain.”
A Reality Check for Renewable Energy
The surge in electricity demand underscores the limitations of wind and solar energy. It challenges the belief that these sources can entirely replace fossil fuels. While Big Tech companies emphasize their commitment to renewable energy, the reality is that their operations rely on consistent power that renewables alone cannot provide.
This situation forces a stark choice: prioritize reliability or green energy. Acknowledging this trade-off is essential for advancing realistic energy transition strategies. Without this recognition, achieving net-zero goals could remain out of reach—potentially affecting not just industries but the planet itself.
