But as the mood toward AI starts to sour, the tides have started turning against data centers as well. 1 IEA analysis based on Masanet et al. (2020), Malmodin (2020), Hintemann & Hinterholzer (2022) and reported energy use data from large data centre operators. Pew Research Center has not surveyed Americans about the potential effects of data centers specifically.

• In 2023, U.S. data centers alone consumed 176 terawatt-hours (TWh) of electricity—equivalent to powering 16 million homes for an entire year.
• His work has taken him as far away as Texas and Louisiana to report on the petrochemical industry and as close to home as Greene County, Pennsylvania to cover the shale gas boom.
• This drives investment in redundant power systems, backup generators, and UPS systems, all of which consume additional electricity.
• “Natural gas supply is critical as we forecast that U.S. liquefied natural gas exports expand and electricity demand rises through 2027, driven largely by increasing demand from large computing facilities, including data centers.”
• But public backlash could also prompt regulators to impose new rules on hyperscalers, Einstein added, “which is really not what they want.”

Data center computing is significantly more energy intensive than computing in general. By 2050, as much as 7% of all U.S. commercial floorspace requires additional energy to meet data center demand across most building types. As noted in a science paper on smart grid technology, maintaining grid parameters within a desirable range even under high-demand circumstances is a core function of modern energy systems.

What is a data centre?

In Ireland, data centers now consume 22% of the country’s total electricity—a stark example of how concentrated development can strain local power grids. Renewable energy does provide electricity for nearly a quarter of the more than 4,200 data centers in the US, especially in sunny areas in the south and southwest. AI models consume enormous amounts of fossil-fuel-based electricity, significantly contributing to greenhouse gas emissions. The need for advanced cooling systems in AI data centers also leads to excessive water consumption, which can have serious environmental consequences in regions experiencing water scarcity. Currently, fossil fuels, including natural gas, provide nearly 60% of global data center electricity, with coal as the single largest source, driven by numerous facilities in China.

Cooling Systems: The Necessary Overhead

Understanding where energy flows within a data center helps identify optimization opportunities and informs infrastructure investment decisions. Compared to the industry average of 1.56, a facility achieving a PUE of 1.09 uses approximately 84% less overhead energy per unit of IT equipment energy. Modern AI processors are 99% more efficient than 2008 models, and this trend may continue.

CBRE expects preleasing rates to remain in the mid-70% range in 2026, well above the historical norm of 40% to 50%. Even with a 43% year-over-year expansion in primary-market inventory, demand shows little sign of cooling. The industry’s pivot toward 500-MW-plus AI campuses has pushed construction schedules into multi-year territory, driven by the need for multiple on-site substations and, in many cases, new high-voltage transmission infrastructure.

Natural gas plants and other generators in the electricity sector supporting U.S. data centers consumed approximately 211 billion gallons of water in 2023. According to the Lawrence Berkeley National Laboratory’s 2024 report on data center energy usage, American data centers consumed approximately 176 TWh of electricity in 2023, representing 4.4% of total national energy usage. IEA estimates suggest that by 2024, electricity demand will reach 183 TWh, representing slightly more than 4% of overall U.S. electricity consumption.

Forecast electricity sales to the residential sector, which largely depend on year-to-year temperature fluctuations, grow on average 0.7% between 2020 and 2026. Finally, while not a natural gas exploration, transportation, or refining company, GE Vernova (GEV 3.08%) supports the infrastructure of natural gas plants through its turbines. As one example, GE Vernova announced that Crusoe ordered 29 gas turbine units to meet its data center needs. If inference workloads scale into more latency-sensitive, distributed architectures, edge data centers could see renewed relevance.

• Vincent is a frequent moderator, interviewer, and keynote speaker at industry events including the HPC Forum, where he delivers forward-looking analysis on how AI and high-performance computing are reshaping digital infrastructure.
• Additionally, the study highlighted differences and technology efficiency challenges amongst the leading cryptocurrency platforms—Bitcoin and Ethereum.
• Neocloud providers, GPU-as-a-service platforms and AI startups, many backed by aggressive capital deployment strategies, are actively competing for full-building and campus-scale capacity.
• Since data centers are often geographically concentrated, they can significantly strain the power grids.
• Each training session can take weeks or months, consuming massive amounts of electricity.

In September 2022, Ethereum transitioned from a proof-of-work consensus mechanism to proof-of-stake, which is expected to slash energy use by 99.95%. As blockchain applications become more widespread, understanding and managing their energy use implications may become increasingly important for energy analysts and policy makers. Understanding data center electricity consumption requires looking at both current usage and projected growth trends that paint a dramatic picture of our digital future. As of 2024, natural gas supplied over 40% of electricity for U.S. data centers, according to the IEA. Renewables such as wind and solar supplied about 24% of electricity at data centers, while nuclear power supplied around 20% and coal around 15%. Global data center capacity demand is projected to grow by three and a half times between 2025 and 2030, driven by the rapid rise of AI workloads.

Looking into how AI and cryptocurrencies, hosted inside data centers, are raising energy consumption, the IEA said that taken together, both technologies will double facilities’ electricity usage by 2026. In 2022, 460 terawatt-hours (TWh) was consumed https://angliannews.com/ukraine-s-energy-sector-investment-opportunities-in-renewable-energy.html by data centers, representing two percent of all global electricity usage. “It is misleading to assert that the capacity market results are simply just a reflection of supply and demand,” the watchdog said, describing the rapid load growth from data centers as “unprecedented.” PJM’s watchdog said the grid may have seen tight power supplies without data centers, but the demand growth would have been slower and allowed more time for the market to address it.

But with “astronomical” data center demand, switching them off didn’t make sense to him. The 2020 rules that the company cited as a reason to retire the plants early pertained to bottom ash transport water, and flue gas desulfurization wastewater. These rules put limits on levels of toxic metals like arsenic, mercury and selenium in wastewater that can be discharged from coal-fired power plants into waterways.
