I would love to get an affordable electric for my local driving, it would suit me perfectly. On the other hand, I gotta keep my F-150 for real driving.
A Nissan Leaf takes about 16amps @ 220 volts for 8 hours. Less than 100 round trip. If you leave the lights off. Do the math for you local power company’s rate for amps.
Remember that as gas cars are pulled off the market the govt will pass new laws to place those lost taxes on the electric car owners. So electric car costs are going to skyrocket.
Yup. Scary.
Actually, I was surprised that it's comparable. I guess the plus side is that auto pollution can be moved away from cities.
On the downside, this calculation doesn't include the environmental damage caused by batteries.
The flow chart is from the Energy Information Administration, part of the Department of Energy. They have one for total energy, electricity, coal, petroleum and Natural Gas.
They are updated every year but now they only make PDFs instead of pic files.

>> Yet there I was, driving the first generation of a car that comfortably hit 85-90% efficiency!
Misleading and dishonest. My guess it, that number is only for the efficiency of conversion of the battery’s stored energy to horsepower at the motor shaft. There’s a whole lot more to it than that.
Yes. Read on down the thread.
Right; I saw the graphic after I posted.
And as usual the entire thread is about private passenger cars.
I still maintain that the real electric potential is in local fleet use such as delivery vehicles or taxis.
What we need is a healthy dose of Free Market Capitalism.
Still too limited by range for a vehicle that needs to run for a full shift. 8 hours of driving is not yet reasonably economic in all electric. Hybrids fit that better with start and stop driving using regen braking.
Batteries work worse in cold weather plus you require more energy to push a vehicle through the snow
LWR nuclear runs cooler than coal fired, so 33% versus 38% for newer coal boiler with superheat steam. Gas turbine combined cycle currently score 59%.
Lose charging the battery, lose drawing from the battery, and have to carry battery weight with the car.
An on-board electrical generation device, a fuel cell as an example, would double to not quite triple fuel economy versus the gasoline power-train.
Ian Wright, a co-founder of Tesla, went his own way and builds hybrid heave truck systems.

It was just a matter of economics, we needed something newer we could afford and this fit the bill.
It's nicely equipped with power windows, power locks, power mirrors, air, heated seat etc.
It's on off lease with only 2,500 miles.
