Will electric vehicles really put an end to gas cars?

Electric vehicles seem to be on a roll.

Several countries, including Britain, France and India, have said they want to end sales of gasoline and diesel cars and light trucks in less than 25 years. Auto makers are following along—Ford F, +0.25% General Motors GM, -0.65% and VolvoVOLVB, +1.70% all have ambitious plans for electric vehicles.

Yet electric models accounted for less than 1% of cars sold in the U.S. last year and only a bit more than 1% of those on the road world-wide.

The Wall Street Journal asked three experts for their predictions on the future of electric vehicles: Tony Seba, an author and entrepreneur; Kate Gordon, senior adviser at the Paulson Institute, a think tank focused on U.S.-China relations and sustainable economic growth; and Nawar Alsaadi, an author and principal at investment-advisory firm Semper Augustus Capital.
