One of the splashier announcements at the Bonn climate talks this week has been the rollout of the Powering Past Coal Alliance — a pledge by roughly 20 countries (so far) to phase out use of coal in power generation by 2030. The countries include Canada, the U.K., several other European nations, New Zealand and more.
In a typically showy ceremony in Southern California last night, Tesla CEO Elon Musk unveiled a sleek prototype electric semi-truck that he said will travel 500 miles on a charge, go zero to 60 mph in 20 seconds fully loaded, and charge most of the way in 30 minutes while a driver rests and eats. He appeared to say that the vehicle will be able to operate semi-autonomously in convoy, which would be the first step to self-driving trucks.
Why it matters: Musk did not say how much the truck will cost, but that it will be cheaper to operate than a standard diesel. If he is able to deliver the semi-truck as described, it seems likely to shake up the freight market just as he has the car business. Experts expect semi-truck traffic to surge in the coming decades as the global population grows to 9 billion people.
