Christopher Karatsonyi (Car Maniac) on Electric Mobility
At Intersolar Europe in Munich, Kai Zimmermann met with the well-known electric mobility expert and YouTuber Christopher Karatsonyi (Car Maniac). Together, they discussed current developments in electric mobility and ideas for the future.
We are particularly pleased that Christopher’s guest article, “Electric Mobility: Which Came First, the Chicken or the Egg?” enriches the book “Beyon Green – Sustainability without sacrifice”
„Electric cars are efficient, cost-effective, and available in all vehicle classes with fast charging speeds and long ranges—and what’s more: driving an electric car is fun!“
