UK to ban sale of new petrol and diesel cars from 2030: FT

All new street lights (as of a couple of years ago) have to have charging points built-in, (or perhaps it's every alternate one or whatever) which I think is good, and also a good way of ensuring a gradual increase rather than trying to set arbitrary targets each year and do random disconnected things to meet them.

If anyone wants to see an example of light pole charging, the Fully Charged YT channel had an episode of one example:

See also pop-up chargers for streets without poles:

Do you have a reference for this because it seems unlikely to be true. The difference in wiring guage between a 100w light and a 3kw is very significant.

Edit: this article talks about one street in London being the first to have car chargers built in an is from March this year.

It is true. Have an example load of pictures: https://duckduckgo.com/?q=street+light+electric+car+charging.... My city (not London!) has had them for >3 years that I remember.

The main difference is that (a) each street light is actually ~ 10W, and (b) the wiring is massively over-specified. Quoting from a local authority source for street lights, [1], the minimum conductor area allowed (for the 220-270 VAC supply) is 6 mm^2, for a total thermal current limit of around ~55A. If you have, say, 100 lamps on a single "ring main", you still only have a power draw of ~1 kW, where the cable is rated to 55 V x 220 A ≈12.1 kW minimum.

Tesla's new fast chargers support 250kw peak per car. So even 12kw is nothing to write home about. How many poles is that shared between? If it's more than 4 then it's not really enough. I suspect the reason the conductor is over specified though is to avoid voltage dropping outside of the 10% range it's allowed.

What's the carbon footprint of all the extra copper needed for the heavy gauge wiring?

I was under the impression that you're not guaranteed 3Kw from everywhere, probaby just a trickle charge overnight...

3kw is a trickle charge. Even the previous generation leaf had a 24kwh battery. From flat to fully charged would be overnight. 60kwh is more like what you need for similar range to a petrol car.
