The world is witnessing a pivotal moment in the energy transition, as clean electricity sources take center stage. In a remarkable development, low-emissions energy met all new global electricity demand in 2025, leaving fossil fuels in the dust. Solar power, the star of the show, accounted for three-quarters of this new demand, with wind power picking up the rest. This shift is not just a blip but a turning point, according to energy think tank Ember.
The Rise of Clean Energy
Clean energy sources, including biofuels, hydropower, and nuclear power, provided a record-breaking 42.6% of the world's electricity in 2025. While fossil fuels still dominate, Ember believes this year marks the beginning of their decline. By 2035, they predict a significant drop of 10-20% in fossil fuel's share of the electricity market, with clean energy taking the lead.
A Turning Point or a Temporary Trend?
Not everyone shares Ember's optimism. Some experts argue that meeting average demand with clean resources doesn't guarantee a permanent shift, especially during extreme weather conditions. They believe the true test lies in meeting peak demand consistently. However, Ember highlights that 2025 saw average demand growth, not extreme conditions, and the world has exceeded expectations in responding to energy challenges.
Global Impact and Regional Shifts
The global tipping point was reached due to significant changes in two major emitters, China and India, who scaled back fossil-generated electricity for the first time this century. This shift, along with Europe's increased renewable energy rollout post-Ukraine invasion, has led to a significant increase in clean energy production. The International Energy Agency also reports a slowdown in oil and gas demand, not just in electricity generation but across the entire energy mix.
The Future of Fossil Fuels
While some hydrocarbon analysts argue that fossil fuels remain essential for stability, especially in regions like Europe, Japan, and Korea, others believe that repeated shocks in the fossil fuel market could lead to a permanent change in energy policy. The current war in the Gulf, and the potential for governments to shield vulnerable households from price rises, may further accelerate the decline of fossil fuels.
Is It Enough for Climate Goals?
Despite the impressive progress, the march of clean energy is not yet sufficient to meet the Paris Agreement's goal of limiting global warming to 1.5 degrees Celsius. The International Energy Agency suggests that fossil-generated electricity needs to drop by 25% by 2030, a more ambitious target than Ember's current prediction. However, the reduction in emissions per kilowatt-hour is encouraging, with the IEA predicting a further drop in the coming years.
Conclusion
The energy landscape is evolving rapidly, and the rise of clean electricity is a significant step towards a more sustainable future. While challenges remain, the world is making strides in decoupling economic growth from CO2 emissions. As we move forward, it's crucial to continue supporting and investing in clean energy sources to ensure a stable and environmentally conscious energy future.
