According to Fast Company, Volvo is planning a move to 100% hybrid and electric cars.

Between 2019 and 2021, Volvo will launch five 100% electric cars–three Volvo models and two under Polestar, its premium brand. The rest of its new models will be either hybrid plug-ins or hybrids that generate power from braking.

The company is moving towards electrification more quickly than it initially thought was possible. In 2015, when Volvo first announced a plan for electrification, the company’s senior vice president of research and development said that the Volvo would focus on hybrids and that it would take time for fully electric cars to be viable.

But battery costs have plunged, falling almost 80% between 2010 and 2016, and are likely to fall further. Charging infrastructure is spreading. New regulations, like an EU law that limits CO2 emissions for cars, and France’s newly announced phase-out of internal combustion engines by 2040, mean that traditional technology has to change. And customer demand is increasing.

Electric cars don’t solve all the problems cars cause of course, such as urban sprawl, pedestrian deaths, obesity, and wasted time. But they solve the air pollution problem (locally, at least, and regionally if there is also a shift to cleaner power plants) and the problem of producing, refining, transporting and storing large quantities of toxic and carcinogenic gasoline and diesel fuel.
