The source for the podcast, an article from Transport Security International Magazine, discusses the issue of air pollution in ports caused by large ships using diesel generators. The podcast advocates for the widespread adoption of shore power, a system that allows ships to plug into an electrical grid at port, reducing emissions. The podcast highlights the critical need for standardization of shore power connectors to ensure global compatibility and facilitate the transition to cleaner air in ports. The podcast goes on to specify several relevant international standards established by the International Electrotechnical Commission (IEC) that govern the design and implementation of shore power systems.
