The issue of supplying cruise ships with shore power has been a topic in the opinion section for some time. Ports like Juneau, Alaska, and Seattle, Washington, have heavily invested in their infrastructure to accommodate Princess Cruise ships and have been quite vocal about how “green” they’re becoming.

To properly supply ships the size of the Carnival Fantasy would require voltages of 6,000 to 12,000; much more than the industry standard of 440-480 volts commonly supplied to ships in repair yards or drydocks. Also the power required would run in the neighborhood of 100,000 to 200,000 kilowatts per day.

The average American household uses less than 900 kilowatts per month. This brings me to the point I’d like to make.

The people grabbing the “green” flag and charging up the hill need to recognize that electricity has to come from somewhere, and the amount needed to power cruise ships will need to come from some very large electrical generating plants that use — you guessed it — non-renewable fossil fuels to run their boilers, engines, turbines etc.

The “green” crowd should just come right out and say it: Not In My Back Yard. They think that requiring cruise ships to use shore power will keep the air clean. Well, at least around the harbor it will.

Meanwhile, folks who live near or around or work in the big electrical generating plants will pick up what the folk on High Battery aren’t seeing. Socioeconomics and politics is driving this. Is anyone surprised?

I, for one, am not.
