I doubt Exxon agrees that electric cars will replace the internal combustion engine.
I can give you many reasons why electric cars will not “replace” ICE vehicles:
1) Weather. In Arizona car batteries need to be replaced about every year because they literally cook. In colder states the charge does not last as long and Lord help you if you are running a heater or air conditioner while driving over hills.
2) Range. This is self explanatory and the issue will not go away.
3) Power. There is no working battery powered equivalent of an F150 towing a trailer.
4. Electrical infrastructure. The US power grid is unable to handle the power requirements of charging all of the electric cars if even 1/2 of the fleet was electric. It’s not just a matter of energy production, it is a matter of electrical transmission.
But if you believe everything you read on the internet, such as your article, here’s one you might find interesting: http://satireworld.com/us-news-headlines/201305090532/500-lb-bigfoot-baby-spots-elvis-in-ufo/
They say that world gasoline usage will peak in 2030 and begin to fall, and by 2040, 40% of cars and light duty trucks worldwide will be electric.
Exxon has to publish that report for their stockholders.
Exxon acknowledges that they can't predict technology advances or future govt policies and that others predict a shift to electrics both sooner and later
