Still, the exorbitant cost of underground construction leaves much of the U.S. power grid’s 8.8 million kilometers of distribution lines and 180 million utility poles exposed to tree strikes ...

Earthworms move by contracting body segments in a wave-like motion, which is ideal for tight spaces. Interestingly, this robotic version could be used to install power lines underground efficiently.

More than 10,000 solar, wind, and battery projects are waiting to connect to the U.S. electric grid—but they're stuck in limbo because of the grid's limited capacity.

Ameren Illinois announced last week it is using new technology that will help it test sub-transmission power lines to ...
