Sweden takes lead in cutting carbon tracks of shipping
Something unusual is happening in Swedish waters. Crews docking at the Port of Goteborg are turning off their engines and plugging into the local power grid rather than burning diesel oil or sulfurous bunker fuel, which is a thick, black residue left over from refining oil.
"I always knew these extremely dirty bunker fuels were helping produce acid rain that falls so heavily over this part of Sweden," said Per Lindeberg, the port's electrical manager and an avid fisherman. "I was very happy when we could switch off the ships."
Similar high-voltage technologies have been introduced at ports including Zeebrugge, Belgium, and Los Angeles and Long Beach, California. But as at Goteborg, only a small fraction of ships are equipped with plugs, so the benefits from shore-side electricity so far have been limited.
