‘The Troubled Energy Transition’ is the title of a recent essay in Foreign Affairs, the influential foreign-policy magazine. Although some important progress is being made in the transition to renewables, fossil fuels are still dominating the energy system.

Rather than replacing conventional energy sources, the growth of renewables is coming on top of that of the conventional ones. What has been unfolding is not so much an ‘energy transition’ as an ‘energy addition’, the authors write.

So how can the world move forward? How should we move forward? And what about Europe? To answer these questions, I'm joined by someone the New York Times calls 'America's most influential energy expert'.

He is a leading authority on energy, geopolitics and the global economy, a best-selling author, Pulitzer Prize-winner for his book The Prize: The Epic Quest For Oil, Money & Power. His latest book is called The New Map: Energy, Climate and the Clash of Nations.

My guest In Search of Europe's Energy Future is Daniel Yergin, Vice Chairman of S&P Global.
