As I’m sure many of you’ve heard, the U.K. wants to ban the sale of petrol and diesel vehicles by the year 2040. According to the British government, the proposed ban is supposed to lower air pollution and save the penguins or something. I’m sorry, but this is total nonsense. The fact of the matter is, switching from diesel and petrol-fueled vehicles will, at best, do nothing. It is true that electric cars are more efficient than petrol and diesel-fueled vehicles, and they produce fewer emissions post-production. But by switching from petrol and diesel cars to electric cars, you are relying more on the nation’s power grid.
