President Joe Biden travels on Thursday to Philadelphia to pitch the promise of a green economy to union workers skeptical that the solar, wind and electric vehicle industries can deliver the same economic punch for organized labor as fossil fuel-powered refineries and power plants. Biden is trying to reshape the U.S. economy by investing billions of taxpayer dollars in green technology, while forcing companies that want lucrative subsidies being offered to help the push do more of their manufacturing in the U.S. He will visit the Philadelphia Shipyard to attend the steel-cutting ceremony for the Acadia, a union-built vessel that will be used to help build offshore wind farms.
