How Renewables Met All Global Electricity Demand Growth for the First Time

In 2025, the world crossed a threshold that energy analysts have anticipated for decades. According to the 75th edition of the Statistical Review of World Energy, renewable energy sources met the entirety of global electricity demand growth for the first time outside of a major economic recession. This marks a structural break from six decades of fossil-led supply growth, signaling that the global grid has entered a new era.[1]

The data behind the shift reveals the sheer velocity of the transition. The report, co-authored by the Energy Institute, KPMG, Kearney, and Ember, shows that low-carbon power generation increased by 887 terawatt-hours globally. This massive influx of clean electrons outpaced the 849 terawatt-hour rise in overall electricity demand, meaning that the net increase in human electricity consumption was absorbed entirely without the need for new fossil fuel capacity.[1][2]

The primary engine of this transition was solar power, which saw its global generation expand by a staggering 30 percent in a single year. Solar's modular nature—allowing it to be deployed both at massive utility scale and behind the meter on residential rooftops—has made it the fastest-scaling energy technology in history. Wind generation followed with a solid 8.2 percent growth rate.[2]

However, deploying weather-dependent renewables only solves half the equation. The critical mechanism enabling solar to meet continuous demand growth is the parallel explosion in battery storage, which grew by 66 percent globally. This surge in storage capacity allows grid operators to capture excess solar power generated at noon and dispatch it during the evening peak, fundamentally altering the economics of renewable reliability.[1][5]

The combination of rapid renewable deployment and flatlining fossil generation resulted in a historic crossover. For the first time since the dawn of the modern power grid, renewables accounted for a larger share of global electricity generation—33.8 percent—than coal, which dropped to 33.0 percent. This milestone officially dethroned coal as the world's primary source of electricity.[2][3]

Yet, understanding the global energy system requires distinguishing between electricity and total primary energy. While the power sector is rapidly greening, electricity only accounts for a fraction of how the world consumes power. When factoring in transportation, heavy industry, heating, and agriculture, the picture becomes significantly more complex.[3][4]

Total global energy demand rose by 1.7 percent to a record 600 exajoules in 2025. Because sectors like aviation, shipping, and steelmaking remain difficult to electrify, fossil fuels still provided roughly 86 percent of the world's total primary energy supply. This paradox—a greening grid alongside record fossil fuel consumption—defines the current, disorderly phase of the energy transition.[4]

Energy analysts note that this 86 percent figure can be slightly misleading due to the "primary energy fallacy." Thermal power plants burning coal or gas waste more than half their energy as ambient heat, whereas wind and solar are treated as 100 percent efficient. As the world electrifies, the total amount of primary energy required will actually shrink because electric motors and heat pumps are vastly more efficient than combustion engines.[3]

The global averages also mask a deeply fractured, regionalized transition. China remains the undisputed center of gravity for both the old and new energy economies. In 2025, China was responsible for more than half of all new global renewable additions, pushing the share of solar and wind in its generation mix to 22 percent.[1][2]

Yet, because its overall energy appetite is so vast, China also continues to consume more than half of the world's coal. The country is simultaneously building the world's largest clean energy infrastructure and maintaining a massive fleet of coal plants to ensure energy security, illustrating the dual-track nature of the global transition.[4]

In the West, the dynamics differ. The European Union crossed a major threshold, with wind and solar generating more power than fossil fuels for the first time. The United States saw a complex picture where solar met the majority of new electricity demand, but overall emissions still rose slightly due to a localized surge in coal-fired power to meet peak loads in specific regions.[1]

The 3 percent growth in global electricity demand is being fueled by a new era of electrification. The transition of transportation to electric vehicles and the shift from gas boilers to electric heat pumps are fundamentally reshaping the grid, moving energy consumption away from direct fossil fuel combustion and onto the electrical network.[3][5]

Additionally, the rise of artificial intelligence has introduced a new, highly concentrated source of demand. For the first time, the Statistical Review quantified the impact of data centers, which consumed 788 terawatt-hours globally in 2025. While this represents only about 2 percent of total global electricity use, its rapid growth rate is forcing utilities to rethink their capacity planning.[3][5]

The ultimate uncertainty in this transition is no longer the cost of generating clean electrons, but the logistics of moving them. Analysts warn that the next phase of the energy transition will be defined by system-wide execution—building high-voltage transmission lines, streamlining permitting processes, and scaling long-duration energy storage.[4][5]

The global energy system is currently operating in a state of profound contradiction. It is simultaneously achieving unprecedented breakthroughs in clean technology while continuing to rely heavily on fossil fuels for non-electric needs. However, the fact that renewables can now absorb all new electricity demand proves that the hardest part of the grid transition—scaling supply to match growth—has finally been achieved.[1][4]
