Welcome to the second episode of Stepchange—where we explore the technologies and systems that have transformed human civilization.

In Part II of our coal saga, we witness how this ancient rock evolved from household hearths to the invisible force powering the modern world. The 20th century would see coal take on its most consequential role yet—as the foundation of electrical grids that would light cities, power industry, and ultimately reshape geopolitics.

We journey through coal's central role in America's Gilded Age monopolies, the brutal labor battles that defined generations of miners' lives, and the critical part it played in two world wars. We'll see how coal fueled China and India's economic miracles even as it began to fade in the West, and how these competing trajectories continue to shape our climate future.

Coal remains the single largest source of electricity globally and our greatest contributor to climate-impacting emissions. Its story isn't just history—it's the backdrop against which our energy transition must unfold.

Welcome to the debut episode of Stepchange—a podcast telling the stories of human progress. We unpack the technologies, systems, and infrastructure that shape our world.

Coal is the story of a step change—a transformation so profound that it reshaped the course of human history. The rise of coal reshaped economies, societies, and the very way we live. It became the foundation of the Industrial Revolution and powered a new era of progress, but this leap forward came at a tremendous cost.

Coal’s story begins with ancient plants that captured sunlight and locked away carbon over millennia. These deposits, buried deep in the Earth, would one day drive empires and fuel industries that transformed the world. Yet, behind this transformation lies a complex and often difficult legacy.

Even as coal has faded from the forefront of our energy landscape, its fingerprints remain everywhere. The technologies it spawned, from steam engines and the rail to industrial manufacturing, continue to underpin our modern world. At the same time, coal’s legacy is inseparable from many of the challenges we face today, from labor abuse and environmental degradation to global climate change.

In this debut episode, we explore the first chapter of coal's story, from its early discovery and use through the dawn of the 20th century.
