Conversation with Mark Raine, CEO at Mercedes Benz South Africa, Martina Biene, CEO at Volkswagen South Africa and Renai Moothilal, CEO at Naacam. Compared to traditional vehicles, which work by burning gasoline or diesel fuel, EVs are powered by electricity stored in a rechargeable battery. This means they have fewer moving parts and fluids than gas-powered vehicles. The overall climate benefit of electric cars improves based on the source of electricity used to charge them, with clean energy sources like solar or wind, powering the greatest savings.
