Global electricity market - statistics & facts
The global electricity market is undergoing a major transformation, driven by rising demand, clean energy expansion, and infrastructure challenges. As the demand of power for electric vehicles, data centers, and global industries fuels electricity use, countries like China, the U.S., and India lead global growth. Electricity consumption worldwide rose from around 7,300 terawatt-hours in 1980 to over 27,000 terawatt-hours in 2024.
What drives the biggest consumers?
The world's three largest electricity consumers, China, the United States, and India, are also the three most populous nations, and population size goes a long way in explaining aggregate demand. Beyond sheer scale, China's electricity-intensive manufacturing base, the high per-capita usage in the United States fueled by large homes and widespread air conditioning, and India's accelerating urbanization all shape national totals.
On a per-capita basis, however, the picture shifts sharply: Iceland topped European per-capita rankings at nearly 52 megawatt-hours per person in 2024, a figure underpinned by low-cost renewable power, cold-climate heating needs, and energy-intensive aluminum smelting, with Norway following at around 25 megawatt-hours per person.
Data centers emerge as a major demand driver
One of the fastest-growing sources of electricity demand has been the data center sector, fueled by the rapid expansion of artificial intelligence (AI) and cloud computing globally. Data centers consumed 415 terawatt-hours in 2024, representing 1.5 percent of total global electricity use, and that figure is forecast to more than double to 945 terawatt-hours by 2030, the equivalent of three percent of projected global consumption. The United States and China together account for the bulk of this growth.
Clean power gains ground, but fossil fuels persist
To keep up with the growing demand, global electricity generation reached a high of over 30,000 terawatt-hours in 2024, almost triple the annual output in the early 1990s. As countries seek to reduce their carbon footprint, clean electricity generation has seen an increase in the past decade, accounting for almost 40 percent of the total generation in 2024.
Renewable power production, particularly from solar and wind, now accounts for over 30 percent of the global power supply, marking a major shift away from fossil fuels. Use of renewables has been growing year-on-year, with an increase of over 10 percent between 2010 and 2024.
However, fossil fuels are still the main source of electricity generation worldwide. Coal, the highest greenhouse gas emitter of the group, accounted for around 34 percent of the global power mix. That same year, the global installed electricity capacity from fossil fuels reached roughly 4.8 terawatts, still larger than the installed renewable capacity of 4.4 terawatts. As the world's top consuming regions continue to expand their grids and renewables capacity, managing the intersection of digital power demand and the clean energy transition will remain the defining challenge for the global electricity sector in the coming decade.
