IEA released its Global Energy Review, noting that global electricity demand grew 3% in 2025, a rate that outpaced overall energy consumption growth of 1.3%. While total energy demand slowed to 1.3% in 2025, electricity demand continued to rise sharply at 3%, easing from 4.4% in 2024 when heat waves in India and Southeast Asia boosted consumption. The 2025 growth rate remained above the 2.8% annual average between 2014 and 2024 and more than twice the overall energy growth rate. In the United States, power usage increased 2% last year, slower than the 2.8% growth seen in 2024 but more than three times the decade average. The buildings sector accounted for 80% of U.S. power demand growth, driven largely by rapidly‑increasing data center loads. Data center power demand alone contributed about half of the entire increase in electricity consumption in the U.S. A nearly 10% rise in heating degree days during a cold winter also supported power demand by boosting space heating needs. Solar PV accounted for over a quarter of all global energy demand growth, followed by natural gas. Fatih Birol, IEA Executive Director, said that "Electricity consumption is growing much faster than overall energy demand – and one energy source is growing much faster than any other." He added that solar PV had become the fastest‑growing energy source for the first time, with natural gas following closely.
