Capacity for EVs
"Electric cars by 2030 will massively increase generating capacity needed"
Total car and van miles in the UK is around 275 billion pa, which needs ~70TWh of energy.
That's about 20 of current total production, but given the cyclical nature of energy consumption, the increase to peak capacity will be much smaller, as long as the peak time for charging EVs doesn't coincide with the existing peaks.
Looked at the from the other end, an average car covers 20 miles a day [Per gov.uk figures], equating to ~5kWh. Recharging in the low demand period from 11pm to 6am gives an average load of ~850 watts per vehicle; 1.7kW for a 2-car household. I don't buy the argument that EVs mean that we have to increase local or national grid capacities because 850 watts is the sort of power the lights my kids leave on used to use before the move to LED.
