The dump truck, at 45 tons, ascends the 13-percent grade and takes on 65 tons of ore. With more than double the weight going back down the hill, the beast's regenerative braking system recaptures more than enough energy to refill the charge the eDumper used going up.
Marking that trip around 20 times a day, Kuhn Schweitz says the eDumper produces 200 kwh of surplus energy every day, or 77 megawatt-hours a year. A typical dump truck uses between 11,000 and 22,000 gallons of diesel fuel a year. That saves up to 196 metric tons of global-warming carbon-dioxide gas a year.
The world is starting to think differently about energy. This would not have been a reality 10 or 20 years ago. Just ironic that the 1970's or so many cities had started ripping out their electric trams and buses, and the now the "wheel" has turned and electric is coming back strongly.

The eDumper makes a good case for going fully electric with heavy-duty construction, mining, and industrial equipment.
