Wars in future will be along the lines of Afghanistan, Iraq and the Falklands or governments taken over by stealth. Or even gradually flooded by so called 'Migrants' until there are sufficient numbers to make a difference.
Or alternatively, just cut off a countries supply chain, being as most of our stuff comes from abroad. In the event of a war with France, they would just cut off our electricity....

When it comes to electricity this leads to a site that shows a great deal about the real-time use of electricity across the UK.https://gridwatch.co.uk/

Modern cruise ships are electric vehicles, all their propellers are driven by several 10MW electric motors in a pod, the elecricity is generated by a diesel but any engine will do.
One of my sons' ships uses the same pods but powered directly by a diesel engine, because of the complex mechanical arrangements the damn things are always breaking down, if they were electric motors and the diesel powered a generator there would be less problems.
Who knows what will replace diesel? the steam powered Titanic only sank a few years before petrol engined tanks were in action in WWI. Many of us here will remember travelling on holiday in a train pulled by a steam engine. Nothing stays the same

Re: Electric Vehicles
According to the news this evening less than 1% of new car sales are electric cars. They are really only practical in major cities with short commuter journeys (ie Melbourne and Sydney).The NSW government thas partnered with the NRMA (like your AA) to add 24 new quick charging stations to the 32 the state already has - might be other way round. They are hoping that building the network will encourage people to buy electric cars.

I can't ever see electricity ever replacing diesels, not in my lifetime anyway. Diesels are far superior in pulling power, range and economy. The most powerful locomotives in the world are Diesel electrics, and you should know Bruce, you've got most of them down under.

Because of the inefficiencies introduced the pollution per mile is actually increased.

However, engine technology has come a long way since those early days and has long since put the poor old horse into retirement and now is just used by 'Horsey' people and jockeys....
Perhaps the electric motor (which certainly has its uses besides golf trolleys and fork lift trucks) will progress to eventually replace conventional engines, but I can't see that happening in my lifetime, and for me it will always be the poor alternative to a proper engine...I've a feeling, based on what we know now, that 'Magnetics' might be the direction that electric transport might take. With some kind of track built into new motorways providing drive. Could this possibly be already happening with 'Smart Motorways'......
