Take your pick of estimates about the pace of change, but we know we are heading for an electric vehicle, or EV, future. As an aside, yes, we need to persuade more people out of cars altogether. Cleaner, greener public transport, alongside active travel, has to be the subject of heavy investment. But the car will be with us for some time yet. What won't be with us is the internal combustion engine. 

Now, UBS bank reckons 14 per cent of car sales will be EVs by 2025. That's growing from pretty much a standing start of not much more than 1 per cent now. In Wales, we count EV car sales in the few hundreds, but even here the growth has been large—35 per cent growth between 2016 and 2017. But, two decades from now, the job will be complete. The question is: when will Wales decide to genuinely get on board?

We need to overcome a number of barriers. Some are beyond our control: the development of battery technology, better range, faster charging, growth in the choices of models available—that's global. We can hope to cash in through research in our universities, through trying to ensure that our car components sector keeps up with or, better still, keeps ahead of changes. We've even got Aston Martin planning to build a flagship EV here, but what I'm talking about today is the application of that new technology for you and me—in other words, getting people to actually buy and drive the cars and to feel that to do so will be as convenient as their current petrol or diesel.

One of the biggest barriers is where to charge. This is very much in our own hands. What I'd like to investigate is using legislation to overcome this. I'm proposing that all new developments—housing, factories, public buildings, offices, tourist attractions, car parks, whatever it might be—must include charging infrastructure by law. The vast majority of EV users will charge at home overnight. If you're lucky enough to have somewhere to park your car with an EV point, that's what you'd be doing mostly. If we want more people to opt for EVs, though, we need new homes to have those EV charging points pre-installed. If you don't have a parking place, plentiful charge points everywhere and elsewhere will be important to you. We need to invest in retrofitting a wide range of parking areas, for example, but what I'm suggesting today is that, whenever there's a new development, there should, by law, be new charge points. [Interruption.] Yes.
