Yesterday, the show focused on how the growing market for electric vehicles is affecting the supply chain for batteries. Today, how about where to charge all those batteries? Many people have electric cars, and a lot more will by 2025. Global sales will triple by 2025, according to IHS Markit. But it’s not just about the number of cars, it’s also about the number of available chargers. Marketplace’s Meghan McCarty Carino speaks with Jessika Trancik, a professor at MIT who recently co-wrote an article on charger placement for Nature Energy. Trancik says for the EV market to grow, we’re going to need more chargers in the right places, especially at home.
