LEDs were supposed to be one of the great environmental success stories: a revolutionary technology that uses a fraction of the energy of traditional light bulbs. But have they really saved the world?

In our new podcast Stuff Matters, economics and data editor Ed Conway takes an object, cracks it open and reveals the world shaping forces hidden inside.

Each episode follows a trail of ideas that stretches beyond the object itself, uncovering far reaching economic powers that shape how we live.

Along the way, Ed meets fascinating characters, from brilliant inventors to Latin American revolutionaries. He dives into their personal stories and reveals how they’ve changed the course of industries and economies.

Because when you look closely enough, even the simplest things turn out to matter more than you think.
