A good article here on the ABC website looking at EV pros and cons: https://www.abc.net.au/news/science/2018-12-08/electric-cars-revolution-environment/10589270
IC engines will remain in use for decades to come in ships and trains. There will be some transition to electric power for much of this though.
Air travel with their oil-hungry turbines of the jet and turboprop variety will soldier on for many more decades. There really isn't an alternative apart from perhaps bio-fuels. High Speed Rail will be it's main competitor.
Agree, if you look at all the forecasts, EV's won't hit 50% of the global market until mid 2030's. The big part of the problem is the lack of range or choice for buyers, so wanabe EV owners are still buying ICE because they don't have an option yet, especially in Right Hand Drive. Then of course you have the brand loyals, like my boss Porsche Panarama lover who won't replace her current model until the Porsche EV is available.
Tesla can only afford to add one new model every 2.5 to 3 years and they are too small a company to risk getting one wrong and cannot afford another Model 3 fiasco, so growth there is limited with Model Y due in 2020 and a Ute type car around 2022. The traditional American car markers have now jumped on the band wagon but there mass roll out is not due until 2022 or there about and beyond.
The Germans, the argument being did they just completely miss the boat and now in a panic trying to catch up, but expect they will and again mass roll out or at least choice of range for consumers wil not be in the show rooms until 2022 to 2025. To speed things up they are no longer introducing solely new EV models, rather providing as an option EV. Some industry insiders the disadvantage in doing this is you have the constraints of a ICE car design in an EV car thus not taking advantage of what an EV traction system can offer in the car shape and layout. https://phys.org/news/2018-09-late-party-german-carmakers-tesla.htmlhttps://www.ft.com/content/782d053c-76be-11e7-90c0-90a9d1bc9691https://insideevs.com/tesla-ev-transition-surprises-german-automakers/https://www.latimes.com/business/autos/la-fi-hy-0419-tesla-germany-20160419-story.html
Another interesting fun fact, the current growth in Year On Year EV sales is reported to be almost identical to that of cars when first invented. However the biggest industry challenge is the consumer "Range Phobia". People wanting cars that have range they in general don't use. If you woke up every morning to a car fully charged, range of 450 - 500km, how often would you need to recharge/refuel during the day? My wife and I in UAE worked out its once per 18 to 24mths when we drove into Oman and last week when we went camping on KSA border. When we lived back home in Gladstone Qld, it was once every 6mth or so, ie usually a drive to Brisbane or distant camping. For Brisbane, recharge while emptying the bladder and stretching the legs, getting a snack would have worked fine. Camping in most cases would have also worked provided fuel stations had recharge stations.
