I don't know for sure whether expanding hydropower would be economically feasible or not, but BC gets about 85+% of its power from hydro. Tidal power in Alaska is also viable, due to their extreme tides. Link to comment Share on other sites More sharing options...

We are using the word gig differently. 1 GIG is ONE BILLION KWH but to uk trained energy brokers using the phrase GIG every day in conversation they are talking about 1 million kwh for one gig. They don't use the word megawatt when perhaps we should. Link to comment Share on other sites More sharing options...

Alaska is far more likely to implement shore power for cruise ships than a total ban. And, who would shut the Caribbean down, given that the term "the Caribbean" encompasses many different nations? Would they all need to agree to ban cruise ships? I agree with you . Given the fuss that Alaska made getting the Passenger Vessel Services Act modified when cruising restarted they are hardly like to be considering a total ban anytime soon.

Rare WantedOnVoyage Posted November 3, 2023 #31 Share Posted November 3, 2023 I favour a ban on "greenhouse gas" produced by those hectoring and harping about it. But more to the point, this repositioning makes sense and returns Cunard to its core markets. I shouldn't but I blame the Australian deployment for "The Polo Shirt" even being mentioned in these pages. It will be interesting to see what itineraries they come up with... I'd love some "no fly" ones from New York to the Caribbean. Now I need to find some great shots of LUSITANIA laying down a blanket of thick coal smoke c. 1907. Those were the days. 1 Link to comment Share on other sites More sharing options...

Rare NE John Posted November 3, 2023 #34 Share Posted November 3, 2023 Considering also the positive and significant economic impacts of cruise ships docking in the Caribbean; there would be mini-revolutions in certain island countries if “ they” banned cruise ships in that region. Plus, also many workers from South and Southeast Asia would be out of jobs. These hard working crew, and their families back home, depend cruise ship business. The industry will work its way towards a less polluting future. 1 Link to comment Share on other sites More sharing options...

Those regarding biofouling of the hull Once again, ace, you have your facts wrong. World wide TOTAL shipping (tankers, bulkers, container ships, ferries, cruise ships) amounts to 3% of total greenhouse gas production (so your number is wrong), and cruise ships account for less than 5% of total world shipping (so you are about an order of magnitude out). The rest of the global transportation system (buses, trucks, cars, trains, airplanes) account for 17% of GHG emissions, yet 80% of the world's economy moves by sea. And, finally, ships, including cruise ships are working to reduce GHG emissions, as witnessed by Viking Cruises working to install hydrogen fuel cells on all their newbuild ocean ships, and Royal Caribbean already having small scale hydrogen fuel cells on some of their ships. Not to say these projects have hurdles to overcome, and years of development for safety standards, but the change is coming. Might want to get out and read a bit before quoting figures. Havila is another line which seems to be making considerable strides with reducing emissions and fuel economy. 1 Link to comment Share on other sites More sharing options...

Was this common behaviour or a one off? Since she was a steamship (hence the SS designation), that was most likely lighting off a boiler, which almost invariably involved incomplete combustion. One of many reasons there are very few steam ships around anymore (mainly just LNG tankers). 1 Link to comment Share on other sites More sharing options...

Does that make sense? There are two types of tidal power generators. "Tidal barrage" type plants use a hydro-dam to retain high water on one side or the other of the dam, and then use that "potential energy" from the height difference to generate power in the turbine. This tends to extend the tidal periods behind the dam to much longer into the 12 hour tidal cycle. "Tidal turbines" are similar to wind turbines, but the blades are underwater, and use the "kinetic energy" of the water flowing with the tides to generate power. While the water flow does slow during the ends of the tidal cycle, it almost never truly stops. Tidal turbines can be used in places that don't have extreme tides (like Anchorage), such as rivers. Due to water's relative density to air, tidal turbines can generate many more times the power per square foot as wind. The problem with tidal power is the initial cost. 1 2 Link to comment Share on other sites More sharing options...
chengkp75 Posted November 3, 2023 #40 Share Posted November 3, 2023 Another factor against "closing down" Alaska, is that it is within the North American ECA, which mandates use of 0.1% sulfur diesel fuel, and not the 0.5% sulfur residual fuel that can be used outside the ECA (200 nm from coast of North America), so that is a 80% reduction in emissions right there, let alone the worldwide reduction in fuel sulfur content from 3.5% to 0.5% in 2020 (an 86% reduction in emissions worldwide).

Rare foodsvcmgr Posted November 3, 2023 #43 Share Posted November 3, 2023 Ex Londoner - this ship was originally Costa’s “Federico C.” built in 1958, so she was around 27 years old at the time. As I recall this was not typical of the entire cruise but nonetheless an example of something we don’t see anymore. 1 Link to comment Share on other sites More sharing options...
bluemarble Posted November 3, 2023 #44 Share Posted November 3, 2023 For the record concerning where QE will be positioned for her Caribbean season, several media reports have mentioned she will be sailing out of Florida as we might expect. I share others' questions about how that might impact QM2's usual Caribbean schedule sailing out of New York in the future. 1 Link to comment Share on other sites More sharing options...

Rare Megabear2 Posted November 3, 2023 #46 Share Posted November 3, 2023 (edited) As Japan is going too how long will the Alaska season be?

Poole Boy Posted November 3, 2023 #47 Share Posted November 3, 2023 Interesting decision, I would have thought that the Caribbean being almost at saturation point from a cruise ship perspective Cunard would have a hard time selling QE at premium prices for 6 months of the year. 1 Link to comment Share on other sites More sharing options...
Rare WantedOnVoyage Posted November 3, 2023 #48 Share Posted November 3, 2023 Having dumbed down Holland America Line to near Carnival standards over the past decade, there really are no vaguely traditional cruise options to the Caribbean anymore so QUEEN ELIZABETH would fill a void of Carnival's own making. Of course, the real saturation point is that reached and exceeded in so many of these ports... four or mega ships, and they are simply overwhelmed. And there is no "aren't cruises horrible and destroy the planet" nonsenses from the locals, either... tourism is THE industry so the ships will keep coming and before long fighting for quay space. Looking for quiet solitudes when cruising? Cross the North Atlantic in QM2... that's about the last unspoilt bit left! 2 Link to comment Share on other sites More sharing options...
