Just Stop Oil ....
A cry we hear daily.... but without viable, effective and instant alternatives, how can we 'just stop oil'?
... but if we 'just stop oil' what do we replace it with? I did hear a suggestion that we return to sailing ships but is that really a viable way forward? Imagine the millions of tons of freight being transported worldwide under sail - not to mention the effect it would have upon all the passenger ships and ferries across the globe. Just pondering here.
All suggestions welcome.

(it's being trialled in Germany and Sweden and if successful will see off railway freight forever).
the biggest transport problem, though, rests with international shipping, which accounts for 3% of all global emissions. again at this time there's no credible alternative to diesel powered ships, other than possibly to run them on LPG, which isn't much less polluting.

The key point is ‘at the moment’. Alternative fuel sources have to be developed. What is impossible today, what is impractical next year May be everyday by middle of the century. This is why energy companies need to develop brand new thinking (as evidenced by the link I posted earlier).
There are so many things we take for granted today that we couldn’t have even *imagined* in the 70s - I’m sure human ingenuity will win out.

The future is what is happening in Chile with Porsche, Siemens and ENAP et al in having just opened a plant to make 650 mln litres of petrol and diesel from CO2 in the air. I have written about this several times before.
Take CO2 in, react it with green or white H2 with lots of hydro-electricity and create a methanol molecule and then synthesise the hydrocarbon you want - at $0.74/litre cost - when refined products come in at about $0.65/litre.....and before subsidies and real scale-up though the project is already a healthy size.
Ideal for places like scotland, Wales, Norway, the Alps etc....and the CO2 becomes a huge sink once it is sucked into the system and emerges from the car tail-pipe, and keeping the existing car park, garages and jobs - and given all the gas and pollutants it took to make them.
No wonder the Germans have had the EEC step back from the 2030 cliff for hydrocarbon cars but what do our dithering idiots in the HoP do, efffing nothing.
By the way, this is an old process called Fisher-Tropsch that I studied for my chemistry O-level and the Germans and South Africans used in WW2 and Apartheid respectively - using coal gas to synthesise up into hydrocarbon fuels.
Spead the news!

Electrify the motorways.
Now stop for a minute and remember where you live and how massive infrastructure projects are mismanaged on a daily basis.
There are some countries in which this might be a goer, the UK is not one of them. We like to think long, hard and small, have a half-hearted go at it then scrap the whole thing.

Strange. Maybe this is the reason:

The article has a paywall but you can read enough to glean that Japanese car makers have been slow to embrace the EV market. Maybe they don’t want to miss the hydrogen ‘bandwagon’ as well?

The whole idea of just stop oil is unworkable. If the world stops using oil today there would be no - vehicles, engines, machines, airplanes,trains, ships, anything with moving parts that needs a lubricant, and countless thing in our lives made from petrochemicals. We would instantly turn the clock back two hundred years. The only alternatives are new green energies and newly developed energies which are still in their infancy.
