How Solar Became Cheap

Energy vs Climate

Send us a text

The cost of solar power has decreased by a factor of 1,000 over the last fifty years, and by a factor of 10,000 since it was first used to power a satellite in the mid-1950s. According to the International Energy Agency, in some sunny regions solar is now the cheapest energy available – cheaper than coal, gas and wind. What have we learned from solar's multi-decade cost curve decline? How did it benefit from a free flow of ideas, equipment and people across national borders? What lessons can we apply to other forms of climatetech, such as energy storage and carbon capture?
David, Sara, Ed, and special guest Greg Nemet break down solar’s trajectory on Episode 29 of Energy vs Climate.
