It is typical that the "concerned scientists" that authored the article weren't concerned about overloading the electrical grid with all of the additional power draw from charging electric cars.

Why is every article that proclaims the value and benefits of electric vehicles ignoring the three factors that will give them a black-eye in public opinion?

1. Where does all of the power come from to generate electricity to charge the electric car?

2. How do we put out the fires when the electric vehicles' batteries catch fire on a daily basis?

3. Where does the additional infrastructure come from to charge all of the Electric Vehicles?

The basic math won't add up at the rate the government is promoting EV adoption. Run the numbers.
