There's a lot wrong with this video as most videos on EVs from 2016. The data is sources for electricity production is actually over a decade old now (Sep 2013) and it rationalizes that the electric cars will break down before the grid ever moves towards greener sources. This is a very silly notion considering solar is straining the grid with too much power at times, times where EVs could charge. They can also charge over night encouraging nuclear power to be more financially feasible as nuclear relies on a base load as they don't like to turn off.

They're not a silver bullet and in some cases like the Hummer EV they are worse than an old car but if you have to drive a lot it is completely less carbon intensive than an ICE for most EVs.

Here's a still pretty old but more nuanced video: https://piped.video/watch?v=6RhtiPefVzM

The greenest car is a train car.
