The Energy Institute’s Statistical Review of World Energy 2026 reveals a complex narrative about the energy transition. While some observers interpret the data as indicative of a rapid shift towards renewable energy, others argue that the continued dominance of fossil fuels signifies a failure in the transition process.
This divergence in opinion stems from the emphasis placed on different components of the energy system. Much of the analysis centres on electricity, where renewable sources have indeed made significant strides. The expansion of solar power and battery storage highlights the progress in this sector, with electricity’s share of the total energy supply rising from 17.1% in 2020 to 19.3% in 2025.
Energy transition: Renewable Energy Growth Amidst Fossil Fuel Dominance
Despite the positive trends for electricity, the broader picture reveals that fossil fuels continue to account for a substantial portion of the global energy mix. In 2025, fossil fuels represented 86.3% of global energy, only a modest decline from 87.5% five years earlier. This reality underscores the ongoing reliance on oil, natural gas, and coal, even as renewable sources increase their presence.
Electricity’s Role in the Energy Landscape
Electricity is becoming increasingly vital in the global energy landscape. The growth in its share reflects the electrification of various sectors, including transport, buildings, and industry, alongside rising demand from digital technologies and artificial intelligence. The rapid expansion of renewable energy—growing from 3.9% to 5.9% of total energy supply in five years—demonstrates that these technologies can achieve remarkable rates of growth, despite the overarching prevalence of fossil fuels.
Understanding Energy Demand Dynamics
The complexity of the energy transition is further illustrated by the dynamics of global energy demand. As economies develop and populations grow, energy consumption continues to rise, averaging an annual growth rate of 1.4%. This increasing demand means that even with significant investments in renewable technologies, fossil fuel consumption can persist, as new energy sources primarily meet burgeoning needs rather than displacing existing fossil fuel use.
Policy Shifts: Energy Security and Decarbonisation
Recent geopolitical events, notably the disruption of Russian gas supplies, have prompted a shift in energy policy focus. While decarbonisation remains a critical aim, energy security has become equally important. Governments now view renewables not only as tools for reducing carbon emissions but also as strategic assets that enhance energy independence and resilience.
This evolving perspective indicates that the energy transition is driven by a broader array of objectives beyond climate policy alone. The Statistical Review illustrates that electricity, while expanding rapidly, still constitutes less than one-fifth of the total energy system. The remaining majority continues to rely heavily on fossil fuels, which complicates the narrative around the energy transition.
A Complex Yet Clear Path Forward
The findings of the Energy Institute’s Statistical Review do not suggest that the energy transition is failing; rather, they highlight a more intricate phase of change. The simultaneous growth of renewable energy, electricity, and fossil fuels illustrates that the world is experiencing an addition of energy supply while gradually shifting its composition. The pace of this transition is influenced not only by technological advancements but also by the persistent rise in global energy demand.
