What are the realistic pathways off of fossil fuels and towards a world of abundant clean energy? TED Countdown asked leaders around the world to take on this core question of the climate crisis, including tension between the necessity to extricate ourselves from fossil fuels, which endanger our collective future, and the equally paramount necessity of a stable and secure supply of energy for everyone.

This preview is part of a longer documentary based on TED Countdown’s Dilemma Series — events that bring together credible people who disagree on a critical climate issue in order to share diverse perspectives and identify solutions. Watch the full documentary here:
