I do about 20k a year. I average about 4 miles per Kw so thats 5,000 Kw a year. I pay approx 14p per kw so that’d be £700 per year for my fuel.
Some electricity tariffs are as low as 5p per Kw so that’d be £125 per year for 10k or about £12 per month. I also have solar panels and work shifts so can occasionally charge for free through the day.
To put that into a context that is easier to understand… I get the equivalent of 180 mpg
