Get ready for a bold statement: the world is witnessing the end of an era, and it's not just any era - it's the age of coal. But here's the twist: even as we bid farewell to coal, a new era is upon us, and it's all about electricity.
The International Energy Agency (IEA), based in Paris, has some intriguing insights. Despite an expected surge in global power demand, they believe we've already hit 'peak coal'. How is this possible? Well, it's all thanks to the 'Age of Electricity', a term that sums up the increasing demand for electricity across various sectors.
A recent IEA report, 'Electricity 2026', paints a clear picture. It predicts a 3.6% annual increase in electricity demand over the next decade, driven by industries, electric vehicles, air conditioning, and data centers. This trend is a continuation of the recent past, with electricity demand growing by 3% in 2025 and a whopping 4.4% in 2024.
Keisuke Sadamori, IEA's director of energy markets and security, puts it plainly: "Global electricity demand is growing much more strongly than it did over the past decade."
And here's where it gets controversial: the IEA predicts that by 2030, half of the world's electricity will come from renewables and nuclear energy, surpassing coal. This shift is largely driven by emerging economies, which account for nearly 80% of the additional electricity consumption through 2030. But advanced economies aren't sitting idle; they're also experiencing an acceleration in electricity demand growth after a period of stagnation.
The report's most striking feature is a graph that shows coal's recent increase, particularly due to massive investments in China and India, but it also predicts a downward trend for the rest of the decade. The peak, according to the IEA, was in 2024, and the new generation is dominated by solar, followed by wind and gas. Nuclear energy, while significant, accounts for a smaller portion.
Renewable energy generation is on the rise, increasing by 9% in 2025, slightly lower than the 9.6% increase in 2024, but still significantly higher than the 6.4% average over the past decade. This trend is expected to continue, with the IEA predicting a growth of around 1,000 terawatt-hours (TWh) annually through 2030, led by solar PV, which is projected to contribute 600 TWh on its own.
Coal generation, on the other hand, has seen a 1.4% increase in 2024, but remained relatively flat in 2025, with declines in China and India being offset by gains in the United States, Eurasia, and other Asian markets. The IEA forecasts a 0.9% annual decline in coal-fired output through the remainder of the decade, although it will still be the largest single source of electricity through 2030.
The decline of coal's relevance is largely attributed to the plateauing in China, which produces over half of the world's coal-fired generation. India's similar decline in coal use, partly driven by renewable energy generation, further highlights the shift away from coal.
The impact of China and India on global coal generation is evident; even as coal-fired generation rose in the United States due to various factors, including federal policy support, global levels remained relatively stable.
The IEA predicts a continued decline in coal's position in China's energy mix through 2030, with increases in renewable and nuclear power generation. Similarly, coal is expected to decline in both the European Union and the United States over the next decade.
However, the IEA forecasts a temporary decline in coal in India, with coal-fired output projected to rise again over the next five years.
So, what do you think? Is the world ready to embrace the 'Age of Electricity' and leave coal behind? Share your thoughts in the comments; we'd love to hear your perspective on this energy transition!
