That assumes that every car in Denmark will consume 50kwh per day. The 64kw Kona Electric will do 300 miles according to the WLTP [1]. So, that assumes every car does 234 miles every day, or over 85k miles per year.

I can't find any solid data, but I'd assume its closer to 10k miles per year, or an eighth of what you're suggesting. That is still a lot, but it is achievable especially with more offshore wind.

Just look how much gasoline and diesel was sold. Anything else will give you tremendously wrong result.
