> Also doesn't gas cost a lot in Germany? Wouldn't that make the total cost of ownership even more compelling for EVs?

Electricity also costs a lot in Germany (for consumers at least), which offsets the savings on gas. Currently I'm paying about 30ct/kWh (Euro, so about 33.5ct/kWh in $) plus a 15€ monthly base fee. Gas is at 1.45€/l (or ~$6.14 per Gallon) right now. Last time I ran the numbers I ended up with a slightly higher cost per km with an EV compared to a normal car - before even factoring in the purchase price.

If you want to charge at a public charging prices sometimes go up 55ct/kwH, due to them having rather significant fixed costs for measuring power (each station needs to have a certified meter). This gets even more significant if you consider the fact that most people in urban environments won't have a house with a garage, which forces them to use public chargers.

Model 3 does about 4.1 mi/kWh. So that's 8.1c/mi (your prices). To pick one example, the A3 TDi does 42 mpg highway. That's 14c/mi. It's more like 19c/mi city. I just picked the most efficient car at the first German company I thought of. Perhaps there are other companies that make more efficient vehicles.

Also, at least in the US, most power companies have some kind of incentive pricing for people who own electric vehicles, if they charge at night. For example, during the summer, ConEdison has a plan under which you pay about 1/5th as much for power from midnight to 8AM. Assuming Germany's electric infrastructure is as advanced as that in the US (I hope!), then that reduces the Tesla's cost to about 2c/mi.

(Not factoring the reduced maintenance cost of a Tesla. Of course if you're really trying to save dough you buy a used Nissan Leaf or something sensible like that.)

While not German I need to highlight the fact that in Germany power generation relies much less to fossil and nuclear than in the US, roughly 1/3 less (~30% compared to ~82%, see links below) That makes Germany a bit more advanced on the generation part but also more expensive - without going into the nuclear debate here. So it is not apples to apples comparison at the end of the day

But Germany appears to rely on Coal more than the USA for power generation.

Coal is the largest source of electricity in Germany. As of 2016, around 40% of the electricity in the country is generated from coal. Germany has been opening new coal power plants until recently, following a 2007 plan to build 26 new coal plants

Compare the energy pie chart for Germany vs USA. (Add brown coal and hard coal percentages)

> As of 2016, around 40% of the electricity in the country is generated from coal.

As of 2019 this is 28%.

> Germany has been opening new coal power plants until recently

While closing many older ones.

Which it didn't.

That's fine, but I used the German parent poster's energy prices in my calculations, and the Tesla was still cheaper per mile.
I should have clarified probably that I was referring to this part of your post: >Assuming Germany's electric infrastructure is as advanced as that in the US (I hope!), then that reduces the Tesla's cost to about 2c/mi.
