Coal’s Long Shadow Fades: The Unstoppable Rise of Renewable Energy

The world has finally broken free from its century-long addiction to coal, a milestone marked by a significant shift in global energy production. For over 100 years, coal reigned supreme as the primary source of electricity, leaving an unmistakable soot-stained legacy behind. However, the latest data shows that renewable sources have surpassed coal’s dominance, marking a seismic shift in the global energy landscape.

The turning point came last year when renewables produced 33.8% of the world’s electricity, surpassing coal for the first time since 1919. This remarkable achievement is largely attributed to the exponential growth of solar power, which has become the fastest-growing source of electricity globally. Solar production doubled in just three years and now accounts for over 75% of the rise in global electricity demand.

The numbers are striking: in 2025, solar produced 2,778 TWh, a feat that would have been unimaginable two decades ago. This achievement is not only a testament to the rapid decline of coal but also a direct result of advancements in technology and economies of scale. The cost of solar panels has plummeted by 75% over the past four decades, making it an increasingly attractive option for countries seeking to transition away from fossil fuels.

China, the world’s manufacturing powerhouse, has played a pivotal role in this shift. Chinese factories now produce around 80% of the world’s solar panels and a significant portion of the polysilicon, wafers, and cells that feed into them. This dominance has driven down costs and made clean power a geopolitical story. As tensions rise over tariffs and trade disputes, it is clear that cheap panels built anywhere cut emissions everywhere.

The demand side has also undergone significant changes. In 2025, China’s fossil fuel generation fell for the first time since 2015, while its electricity demand rose by 5%. India followed suit with a 3.3% decline in fossil fuel generation and a 24% increase in renewables. This trend is not limited to these two countries; globally, new clean energy capacity has outrun new demand.

While this momentous shift towards renewable energy offers cause for celebration, it would be premature to declare victory. Coal’s share of global generation may have shrunk from 41% in 2013 to 33% today, but the fleet itself is not disappearing anytime soon. China, for instance, approved over 40 gigawatts of new coal capacity in just the first three quarters of 2025.

As the world transitions towards a cleaner energy mix, it’s essential to recognize that this shift is not without its challenges. The era of clean growth marks the beginning of real decarbonization rather than its end state. Power-sector emissions in 2025 were still alarmingly close to record highs, and coal’s legacy continues to cast a long shadow over our energy landscape.

The question on everyone’s mind is: what comes next? As countries continue to invest in clean energy technologies, it’s crucial to recognize that the transition will not be smooth. Existing infrastructure, like fossil fuel plants, will take time to decommission, and new capacity will need to be built to meet growing demand. The geopolitics of clean power are complex, with trade disputes and tariffs threatening to disrupt the flow of cheap panels.

One thing is certain: the unstoppable rise of renewable energy has changed the game forever. As we look towards a future powered by solar, wind, and other clean sources, it’s essential to acknowledge that this shift is not just about reducing emissions but also about creating new economic opportunities and driving growth.

The coal era may finally be coming to an end, but its legacy will linger for years to come. As the world hurtles towards a cleaner energy mix, we must be vigilant in our pursuit of sustainability and mindful of the challenges that lie ahead.
