I agree that where folk park on road they are unlikely to reliably park by their own cable trench. If charging points are fitted to lamp posts the trenches may have some function.
Approx 17% of homes are detached, 26% semi and 9% bungalows. In total a little over 50% are likely to have off road parking - any not doing so are likely balanced by flats and larger terraces which do have off road parking.
Some other factors to consider:
- car ownership in urban areas with smaller properties tends to be lower than provincial and rural due to the better public transport and local infrastructure
- occupiers of smaller properties may often be lower income and less likely to buy high cost EVs. Existing ICE can be used for probably the next 15-20 years
- EVs will typically need charging 1 or 2 times a week - can readily be done at work, shops, leisure centres, car parks etc etc etc. Living in a terraced house is not a barrier to EV ownership
Home charging only really makes real economic sense if it is via PV - otherwise the electricity used is through the normal household supply.
Aside from the real risk that government will find a way to tax it anyway, home charging requires investment which will take several years to pay back.
I have considered an EV as I could charge off road. Fitting PVs will cost about £6000. Output will be about 3400KWH pa - if all used to charge an EV would give about 10,000 miles of motoring.
This needs to be discounted as (a) longer journeys will require recharging away from home, and (b) in summer output may meet most motoring needs but in winter (low daylight hours, more cloud) much less. Assume that overall I get ~6000 miles of "free" power.
At (say) 50mpg this saves me buying 120 gallons of fuel. At ~£7 per gallon is an annual saving of £840. It will take around 7 years to pay back my investment of £6000 - rather more as I carry the risk of any maintenance and replacement for the PV system.
IMHO this is not all a big conspiracy for Rishi, Boris and their mates to line their own pockets at the expense of the disadvantaged hardworking etc etc. The world is changing and to thrive we all need to adapt, not whinge because it is no longer 1970.
