In the field of electricity generation, sure. Technology is there, apart from storage technology.

But, given still higher costs and range anxiety, it will be very difficult to convince most consumers to buy electric cars. It will be most probably only generational shift: people born before ~1990 will still buy petrol cars till they die out, and younger generations will progressively shift, having different habits. It will take whole century to fully switch to electric vehicles in developed countries - and lack of reliable electric grid will make it in places like Africa even slower.

An even harder, and even larger part of the story is industrial heat (needs to be very reliable and cheap), and residential heating (needs to be very, very cheap and available in large volumes). No good non-fossil solutions here exist.

In Norway more than 50% of all new cars are electric. They are heavily subsidised, but it proves that it is only an economic question. I was born in the seventies. My next car will be electric. The only reason I’m holding of is that there’s no model that fit our needs yet (except an very expensive Tesla), but I expect that to change within two years.

For industrial heat they will use hydrogen produced from renewable electricity. See for example [0] where it will be used for large scale steel production.

All the technical and economical components for the shift are already in place. The only thing lacking is political will (and apparently knowledge).

> "industrial heat, and residential heating "

For decades Russia has used distruct heating using waste heat from nuclear powerplants, its the chealest heatsource known to man.

More modern approach is probably hydrogen and heat pumps, but either works.

Range anxiety is a brain bug for folks that have never driven electric.

Yeah right, and those are simply older folks. Most of them will never switch. Those who will be only buying their first car in 2030 will probably buy electric, sure, but it will be another 20 years before these people will become the majority of buyers. These people are in the middle school now.

Your belief that older people won't buy electric is completely baseless and untrue.

I'm almost fifty and looking for buying an electric car. My parents just bought a plug in hybrid, but would have bought a fully electric if any suitable was available to a reasonable price.

There is a HN article about using iron for industrial heat. The only downside is that transportation is expensive. If it can be electrolyzed on site it's going to be a game changer.

Range anxiety is only an issue for long journeys.

Cities went from horse-drawn carriages to automobiles because the incentives made it attractive to do it. The same can be done for for electric vehicles, it’s just a matter of putting the horse in front of the cart.

And the incentives are there. Electric cars are quiet, clean, and much cheaper to drive and to maintain.

But apparently not enough for most people, otherwise no one would want an ICE car anymore.

Teslas are too expensive, and the other car manufacturers are behind on getting a full range of models out. I expect that to change the next two years or so.

It happened because Ford T cost 4x cheaper per mile than a horse-drawn carriage, in a city (less difference in the countryside). It was a no-brainer to switch. When your horse died, it would be stupid to buy another when you had an option to buy a Model T.

Same can't be said about electric cars. So far, it's almost at the contrary.

In Europe where the fuel is properly taxed for it CO2 emissions, the lifetime mile cost of an electric car is already lower than corresponding gasoline car.

Except that supply is unreliable...
