On a gray March afternoon at the Port of Los Angeles, the largest in the U.S., powerful electric top-handlers whir, beep and grind as they motor back and forth, grabbing trailers from truck beds and stacking them as they move on or off the mighty container ships that ferry goods across the Pacific. Some of the ships, rather than burning diesel to sustain operations as they sit in harbor, plug into electricity instead.
The shift to electricity is part of efforts to clean up the air around America's ports, which have long struggled with pollution that chokes nearby neighborhoods and jeopardizes the health of people living there. The landmark climate law championed by former President Joe Biden earmarked $3 billion to boost those efforts.
