This book tackles the critical question of how to revolutionize our energy supply without destroying the planet, a central debate for today and the future.

Humanity's existence is entirely dependent on energy, powering everything from our daily lives to advanced AI. However, fossil fuels – coal, oil, and gas – supply three-quarters of our energy, causing climate change, energy poverty, and conflict, while their reserves are finite. An urgent energy revolution is essential, but its form and cost are critical questions, as today's decisions will shape future generations.

Physicist Bjørn H. Samset guides readers through alternatives like wind, solar, nuclear, and geothermal power, explaining their function, potential, and large-scale implications. The book also highlights past energy revolutions, offering a deeper understanding of this complex concept.
