Electric Cars are Not the Solution


20 million cars are on the road and doing a 60 miles round commute every day.  The average engine size produces 25kW of power and on the round-trip commute of about 1 hour 30 minutes they each use about 37.5kWh of energy.  So, the total energy provided by petrol and diesel is 750GWh.

If every car was electric, 750GW is the amount of energy required to recharge the electric vehicles each day in the evening.  From spring to autumn there is usually 5 to 10GW of available headroom in the national grid.  Charging over a 5 hour period this is enough to charge 667,000 cars only.  Presumably the 667,000 vehicle owners would be Government Ministers, Civil Servants, and Senior NHS Managers.

This means the owners of those 19,333,000 petrol and diesel cars would have to give up their vehicles by being taxed off the road.

The electric car costs more than a petrol or diesel car because the typical cost of the lithium-ion battery for a small distance vehicle is about £7000, and despite claims to the contrary this price is not going down any time soon. 

The battery life is quite well known and can fail within a short time of being charged fully for the first time, but the liability of failure increases significantly as the best before date approaches 5 years, with it failing for certain soon after that.

This means that an electric car will have no worthwhile second-hand value.  They use reactive braking on the rear wheel to return the kinetic energy of the vehicle back into electricity to charge the battery.  This means that even with a hint of ice the rear wheels lose grip, and the car goes into a skid. 

You cannot really use the heater in winter, or it severely reduces the range.  There will never be enough of them to justify charging points all around the country. 

Don’t buy one!
