As Green As The Grid: The Biggest Myth About Electric Cars

Electric vehicles are often dismissed as being only ‘as green as the grid.’ But this argument misses the bigger picture. Even on fossil-heavy electricity systems, EVs still outperform petrol cars thanks to their unmatched efficiency. A petrol engine wastes most of its energy as heat, while EVs convert over 85% into motion. That efficiency translates into up to 73% fewer emissions over a vehicle’s lifetime, even when accounting for battery manufacturing. In this blog, we break down why EVs remain a fundamental step forward, what challenges remain, and why the ‘as green as the grid’ myth doesn’t hold up.
