The concept of bunking the traditional engine for a non-gas guzzling counterpart has been here for decades, but creating an ecosystem for battery charging and bringing vehicle costs down was a challenge for decades. The sheer force of Elon Musk’s vision is building the infrastructure needed to sustain millions of electric cars in the United States, Europe, and elsewhere. Most major manufacturers have joined the enthusiasm to ditch old-school engines to construct the international fleet of tomorrow.
