Diesel / petrol banned by 2040 what do we do then

Something will turn up, it always does. Necessity is the mother of invention!

You are assuming that this government will have any time to do anything other than drag us through brexit for the next decade or two. 

Surely you mean lead us to the sunlight uplands of full sovereignty.  Rather than "drag us through Brexit"?

Looking on the bright side the amount of money poured into battery research.  Is surely going to results in more powerful, lighter and cheaper batteries.   Great for off grid and of course the power cuts when demand for electricity exceeds supply when everyone is charging up their cars.  

It seems our law court has now forced our government to take action; by "take action" I mean make an announcement of intention to stop the production of diesels after 2040. Looks like the survivors will need bigger batteries for their motor-movers. 

The court found that the Government had acted unlawfully, by not publishing plans on how the legal requirements for air quality are going to be met.  This needs to be published in draft form by the end of this month. Reports are this draft will only address plans for NOx emissions and not much else.  There is no court banning internal combustion engines.

PS Legislation for air quality is not that new.   The first law was passed in 1306 by Edward l.   I am sure there are some on here who remember how much better in life was in 1305 and it's been down hill all the way since then.

I wonder what will happen to the petro-chemical industries in general and oil producing countries? Surely big changes ahead although I will be too old or not even around by then.

edit Oh, I see I might be around when the switch to electric cars starts in the 2020s 

How long has the caravan industry got to rethink and reform?

I was at a customers site, a large multinational and they have just installed electric charging point in their staff car park. The change will be disruptive but it will come.  Just as the car replaced the horse and cart.  

There are 31 million cars in the UK. How many street side charging points is it going to need? One outside every house?  And what about people who live in flats?
