Coal, oil and gas provide four-fifths of the energy that powers our modern world. But continuing to burn them will mean wrecking the only planet we have. Is there a way out?

In The Future of Energy, journalist and analyst Richard Black argues that there is, and that the transition to a clean energy world is already underway. He shows that with just five key technologies we can replace the burning of fossil fuels almost entirely, as quickly as society decides.

Doing so will do much more than halt climate change. The transition will bring cheaper energy, cleaner air, and more jobs. It will remove some of the factors behind oppression, injustice, and conflict. And it is supported by an overwhelming majority of the world's population. This may not be the story of energy that you hear most about from politicians, business leaders and journalists, but it is the one that matters.
