Macroscien said...One of the first modern GM electric cars EV1 used 11 kwh per 100km.
at 8 cents per kw that mean that 100 km cost you $0.88
versus modern petrol car 7l/ 100 km $9.8 ( my use 11-13L/100km
)
Now with solar on the roof or your home you just need 3kW solar panel that provide all this daily needed juice for your EV for free to the end of your life.
At $1 per 1W of solar panel that mean for $3000 quits you ride to free 100km everyday as long as our SUN exist.
As you can expect solar panel prices are going to drop even further.
What more - for solar panel charging car you don't need expensive inverter and grid connection too.
If there is any need for coal at all ??
I think you also need to put twice as much in to a battery than what you take out
