Summary: Just sitting in port, ships use 10-11 megawatts of electricity—enough to service 10,000 homes. When they’re running, they use 40-95 MW of electricity. New technologies allow cruise lines, ferries and others to cut ships’ energy use by 8-15%, and in some cases, by as much as 20%. Bob Fesmire, media relations manager for ABB Inc. explains how. He also talks about energy efficiency trends in general.
