What is "undergrounding"?

Here's the text you can use to answer:
The costs of the corresponding outages are immense. Numerous analyses show even a one hour power outage can cost commercial and industrial facilities tens of thousands of dollars—and outages often last much longer. In specialized industries like museums, a power outage can mean the difference between a safe, stable climate for art and an environment that starts to quickly degrade priceless artifacts. And as we’ve witnessed in the aftermath of Hurricane Maria in Puerto Rico, damaged grids can claim human lives.

That’s why many people argue for “undergrounding,” the process by which existing utility poles are moved from their current spot above the tree canopy to a protected tunnel below the earth. Proponents, who seem to grow more vocal over the summer as hurricane season picks up speed, say this move would ensure the grid’s resiliency, even in hurricane-prone places like south Florida. But Ted Kury, the director of energy studies at the University of Florida’s Public Utility Research Center, says not so fast. Undergrounding could reduce the number of hurricane-related outages in some places. But these buried lines bring with them their own problems—and price tag.
