Why now exactly? There are still a gazillion oilfields left to suck dry for many many many years to come.we need stuff like this to start developing now
What the car and petrol industry should do imo is start to develop less resourceful engines as they can easily produce them but that's not in the best interest of the oil industry .
Electrical engines might look clean but your striking image is right. The amount of CO2 produced by coal plants to produce electric energy are the real polluters. Not to mention the airplanes flying through the sky or heavy industries.
But lets force the little man to hop into an electrical car eh Unless the electricity comes from a nuclear power plant or is produced by a solar system I will never ever drive a single inch in an electrical "green" car.
