I crossed the United States in an electric car with writer @craigwelch to try to understand the future of energy for our story "The Road to 2070." Please have a look at the April 2020 issue of National Geographic, which marks the 50th anniversary of Earth Day. Check out Nat Geo's link in bio for more on this story.」4月21日 21時07分
