Quiet giant: The electric excavator is still a rarity

Like cars and bicycles, construction machines can be powered by batteries. Although they are much quieter and more climate-friendly, they have hardly been used in Switzerland. Other countries are trying to help electricity companies with regulation: in Norway, for example, public construction sites can no longer be operated with fossil fuels. In Holland, a court had ordered a halt to construction of construction sites that violate emissions guidelines.
