#247 Could EVs + Demand Response Solve Grid Flexibility? | Joseph Vellone (ChargeScape)

We’ve put in thousands of hours to create this project — won’t you spare 5 min to help us make the show even better?What’s up, everyone!Today, we have a great episode with Grace Penders and Adam Chadroff from Equal Ventures. If you're not familiar with Equal, I recommend checking out episode 116 where we had on Rick Zullo, the Founder of Equal.Today, we’re continuing the conversation about the climate tech vibe shift. However, our conversation with Equal is a little bit different. Equal has, from the very beginning, had a thesis broader than just climate. One of those other areas is insurance. This is an area that is increasingly intersecting with climate. This is becoming especially acute given the rise in natural disasters and the catastrophic financial impacts that follow.Our conversation today focuses on these themes as well as what the insurance industry’s role is in helping solve the climate investing challenge. There are plenty of ways. This is playing into how governments engage.Overall, it's an amazing episode and we're really excited to share this with you.Sidenote, we recorded this in person in the equal offices during my recent visit to New York.
