Page down the chart – prices range from 1 cent to 41 cents per kilowatt hour.
The U.S. has an average price of 15 c/KWH. Where I live its about 10 c/KWH but there is a separate monthly charge for the power company’s infrastructure including distribution networks. That makes sense because when you have solar PV net metering (like us), we pay for the distribution network in the fixed part of the monthly fee, and they pay us for excess power production and we pay them when we do not produce enough.
Lower costs, presumably, make access to electric vehicles more compelling.
