A total ban is nonsensical. If you’re concerned about noise regulate the sound level. If you’re concerned about energy use, tax it and put the money raised into a solar subsidy. But the idea you can have a heat pump and can’t have an AC is absurd because a heat pump literally is an AC flipped around.
Domestic connections in the UK are built with an average peak consumption of about 1.5 to 2kW, you can draw ten times that, but its unlikely every house will do that at the same time, so it's just like a contention ratio on a network.
Now imagine everyone charges their car, even if it's only for an hour, but when they get home at 7pm, same time as putting on the kettle and the oven, that's way higher than the substation can provide.
One study put a fully electric car/heatpump/cooking about 4 times the peak demand of an ice/gas heating house, even if total usage is only twice as much, and total energy use is far less than with ICE/gas. Throw in solar and it reduces the total power drawn from the grid, but not the peak amount. Drawing 20kW for one hour is far more expensive to service than drawing 1kW for 24 hours, but uses less energy.
Easily solved with various time-of-use pricing schemes. Have people put their cars on a timer to charge in the middle of the night, or during the day in countries with solar. I already have this for my hot water heating - the water heater only runs during solar hours when there is a cheaper rate.
> Drawing 20kW for one hour
Why would you fast charge if your car is going to be parked at home overnight anyway
Charging one car at 7kW, put the oven on, jump in the electric shower, and you're there before the heat pump even kicks in.
20kW is the about the maximum input to a typical UK home (80A or 100A breaker single phase 216-253V). You can draw that fairly easily.
But a street of 100 houses is not drawing 20kW to each house at the same time, or 2MW to the street. Standard models put it around 200kW. The substation can be overspecced to 300kW and there's no problem.
Convert everyone to electric and that substation needs to be upped far higher.
I live on a new build site still under construction. Until a month ago the site was fed from a long cable from a separate substation. The houses have solar and electric car points.
The voltage varied dramatically and electric chargers would frequently trip (they do that when voltage goes over I think 247V for safety purposes).
And no fast charger i've ever used had a gas generator next to it. Even if it were true (and in the EU it is definitely not) DC fast charging is only small percentage of EV charging.
https://x.com/WallStreetApes/status/2035921843757216158?s=20 This is just one example. EVgo and many other very large charging networks use generators also. Even if you charge at home or anywhere else which you don't see the generator, that electricity has to be made from using coal gas or other stuff, renewables are not a big share in most of them. Those cables transferring electricity loses a lot of energy and gives off lots of heat but you won't see that.
Rare exceptions exist (the other is chargers out in the middle of nowhere, or during construction that impacts the grid connection), if they all used gas generators that cost for a fast charge would be 4x what it is, it's obvious it's not normal.
> that electricity has to be made from using coal gas or other stuff, renewables are not a big share in most of them
If we're talking about Europe as this thread was, fossil fuels are 35% of the grid and dwindling (it was over 50% 20 years ago). Coal is only 11%.
> Those cables transferring electricity loses a lot of energy and gives off lots of heat but you won't see that
Transmission losses are 5%. Transporting oil (be it by ship, truck or pipeline) isn't free either.
Totally understand thanks for the explanation. still it doesnt make sense and answer why are they so strict about using cooling devices. If theyre using renewables and stuff it only makes sense cooling would be more okay that using that same energy to heat houses, yet cooling is just political and restricted. Im in US and i could care less it just reading comments even on here how hard can be installing AC and stuff really doesn't make sense.
