[Episode #280] – Statistical Review of World Energy 2026
The Energy Transition Show with Chris NelderShow Notes
The Statistical Review of World Energy 2026 is out, offering the first complete look at global energy data for 2025. The report's 75th edition, now presented in partnership with the energy think tank Ember, reveals a year in which demand for every form of energy hit a new record high.
But growing overall demand, even for fossil fuels, doesn't mean the energy transition isn't happening. Renewables grew more than any other form of energy for the first time outside of a recession, with solar power accounting for 72% of the increase. And global electrification reached a tipping point, with electricity demand growing 3%, faster than energy supply overall. China alone added the equivalent of Germany's entire annual electricity consumption in a single year. These are just a few of the indications that the future of global energy use is increasingly electric, even as regional paths differ.
In 2025, rising electricity demand was met entirely by low-carbon sources, with renewables and hydro overtaking coal as the largest source of generation. Fossil generation fell overall, demonstrating that fossil fuels are being substituted rather than supplemented.
Solar and storage are clearly taking the lead in the global energy system, and they're not looking back, as global battery storage capacity grew 66% last year alone. Solar already produces more electricity than gas in major parts of the world, and its lead in power generation will only grow.
In this episode, we are joined by Aditya Lolla, Interim Managing Director at Ember, and Euan Graham, Senior Electricity and Data Analyst at Ember and a lead author of the report, to share the key findings from this new update on all the energy data that matters.
We'll dig into the report's new total energy supply measure, which we explored in Episode #259. We'll hear how China's road fuel demand is now falling, redefining the assumed long tai

Over the summer, the IEA projected that carbon emissions from the world's power sector are on track for a new record in 2026. Electricity demand is expected to grow 20% faster than it did a year ago, and this year's gas shock has pushed some countries to use more coal.
When we first created the Energy Transition Show in 2015, solar generated about 250 terawatt hours worldwide. That was roughly as much electricity as California used the same year. A decade later, as the energy transition moved ahead, solar generates more than ten times as much, matching the European Union's total electricity demand.
Transportation continues to electrify, as a quarter of the world's new car market in 2025 was electric, both battery and plug-in hybrids. And this area of the energy transition is already showing up in metrics that matter for the climate. Recent data shows that running a battery electric car on Europe's grid cuts lifetime emissions by more than 70% against a comparable combustion car.
The energy transition calls for more electrification. As transportation, heating, industry, and now power demand from data centers all crowd the interconnection queues, the US needs more transmission than it has built in generations. Even energy transition skeptics can agree on the wires.
Millions of Americans are sweltering under heat domes this summer, with temperatures soaring to record highs when weather systems stall. The grid feels the strain of these events too.
