Erik Saelens discusses risks facing energy brands from "space invaders" like tech companies entering the energy market. He notes that consumers, especially younger consumers, increasingly trust brands like Apple and Samsung more than their energy suppliers. Many consumers would be willing to switch to their preferred tech brands for energy if offered. This poses major risks to traditional energy brand values as deep-pocketed tech companies could leverage lower prices and superior online services to attract customers. Saelens believes this collision of factors has potential to cause massive disruption in the industry through a loss of customers and brand value for existing energy companies.
