Wind and Solar energy assumptions by the warmers greatly exceeds these sources actual capability. Let’s look at how renewable energy plays out as a possible replacement of diesel fuel for container ships. This is discussed in a 27 Feburary 19 IEEE Spectrum posting by Vaclav Smil titled “Electric Container Ships Are Stuck on the Horizon”. It opens up with the following:
Just about everything you wear or use around the house once sat in steel boxes on ships whose diesel engines propel them from Asia, emitting particulates and carbon dioxide. Surely, you would think, we can do better.
When warmers quote emissions from battery powered engines, they always tell us that such engine is “Zero-emissions”. Most batteries charges are provided by fossil fuel power plants. So the real emissions are never zero but rather those emissions from the fossil fuel plant that created the energy to charge the batteries. And more from the posting:
Containers come in different sizes, but most are the standard twenty-foot equivalent units (TEU)—rectangular prisms 6.1 meters (20 feet) long and 2.4 meters wide.. Maersk’s Triple-E class ships load 18,000 TEUs. At the “super slow steaming,” fuel-saving speed of 16 knots, these ships can make the journey from Hong Kong to Hamburg in 31 days.
The author makes a comparison with a hypothetical battery powered container ship and an actual diesel-powered container ship:
That’s a tall order indeed: In the past 70 years the energy density of the best commercial batteries hasn’t even quadrupled.
I have read accounts of “fuel anxiety” that electric car drivers get as they wonder if they can make the next recharging station before the batteries are totally discharged. Can you imagine the anxiety the ship’s captain might have knowing there are no recharging stations in mid ocean.
If the container ships were equipped with a nuclear reactor as in our navy’s submarines, we could probably match the performance of the diesel container ships and actually have a no carbon emissions ship.
