General   (General discussion, talk about anything.)

Retired now, but spent all my working life since leaving school supervising / planning / designing the replacement of old cast iron gas mains with new plastic ones around the North West. Just about finished, & they now demonise gas !!!!

Anyway, As to electric cars, ponder these points. Values are approximate.

Most houses have a 80 amp main fuse (some up to 100)
Car rapid charges at 45 Amps
Shower 45 Amps
Cooker 30 Amps
Have all three at full belt, TV, lights, etc etc and your main fuse blows. You can't replace it yourself.
Lots of houses have two or more cars - go figure
Your house electrical feed is sized at nominaly just over the fuse rating also, so a bigger main fuse won't help.

This design philosophy (load diversity) also goes way up the electrical supply chain, your house supply cable, street cable, feed to your local LV substation, up to your area HV substation, up to the Grid, Generating plant etc etc.

Car parks with lots of chargers ? - Think Tesco Asda - they will require a MAJOR umpteen KV electrical feed, new substations and HV feeder cables - VERY VERY COSTLY INDEED.

Also we have very doubtful spare generation capacity EVEN THROUGH THIS WINTER, add more and more EV's, year on year the whole network will require MASSIVE upgrades and modifications - who will pay ? - why US of course.

Lastly - the cost of EV's. A LOT more than petrol /diesel, and secondhand EV's are a great unknown, especially battery replacements - you're talking £thousands.

Most ordinary folk will be priced off the roads by 2030, and the powers that be know it and want that to happen.
