A particle physicist reveals that energy is not just a quantity in a textbook — it is the hidden story of everything: the universe’s birth, civilization’s rise and fall, the climate crisis, and the one number that could save us.

There is one concept that explains everything — the birth of the universe, the fall of civilizations, the warming of a planet, the life flickering inside a single cell. That concept is energy. And yet, as Richard Feynman once admitted, “we have no idea what energy actually is.” Energia begins precisely there, and takes the reader on a journey that is nothing less than a complete rethinking of reality.

Written with the scope of a manifesto and the precision of a theorem, the book unfolds in four acts:

The first explores the scientific and philosophical meaning of energy, moving from Joule’s experiments and Einstein’s insights to the quantum vacuum, presenting the laws of thermodynamics not as abstract formulas but as the fundamental grammar of reality.

The second traces energy as the hidden force behind every major transition in human history, from fire and the steam engine to the digital age, with a compelling reflection on entropy and on life itself as a temporary act of resistance against universal disorder.

The third turns to the politics of energy, revealing how control over resources has long shaped power, inequality, and conflict — and how it remains the invisible architecture of today’s climate injustice.

The fourth builds on a striking paradox: humanity is not running out of energy, but out of intelligence in how to use it.

The epilogue widens the lens from the universe’s low-entropy beginnings to its distant thermal end, reminding us that we inhabit a rare and still-young cosmos, one capable of generating order, beauty, and consciousness.

Battiston’s scientific authority and non-partisan voice make the book both credible and accessible. Its cosmic perspective — from the Big Bang to the future of civilization — offers readers not just knowledge, but a new way of seeing their place in time.
