While electric propulsion is more efficient, but it generates far less thrust, which is why electric planes tend to be slow. Airbus’ two-seat electric plane could only go a maximum speed of about 136 miles per hour. A solar-powered plane that completed an around-the-world journey this summer had an average …

As we increasingly rely on computers for daily tasks, the energy needed to run these systems is becoming substantial. The total amount of energy the U.S. dedicates to computing has risen dramatically over the last decade and is quickly approaching that of other major sectors, like transportation. Studies show that the …
