Oil: The prehistoric source of fuel that could drive us all into extinction. We need to pivot to renewable sources of energy, like water, wind and solar to save our planet. But is it actually possible to switch ALL energy sources to these renewables? Dan looks at the problems rushing into them can pose, the barriers we currently face, and why we should all have hope for the future.

TED Climate is produced and edited by Sheena Ozaki, mixed by Sam Bair, and hosted by me, Dan Kwartler. This episode adapted two lessons originally produced in animated form by the TED-Ed team. The first, Can 100% renewable energy power the world? was written by Federico Rosei and Renzo Rosei, with support from Emma Bryce and Alex Rosenthal, and fact-check by Francisco Diez. The second, Building the world's largest and most controversial power plant, was written by Alex Gendler with support from me and fact-check by Eden Girma. Special thanks to Alex Rosenthal, Gerta Xhelo, Michelle Quint, Banban Cheng, and Anna Phelan.
