EVs are now increasingly beating gasoline cars on cost of ownership and these often have batteries large enough to store the power required for 4 days of a regular western household.
I doubt you will be entirely without sunshine for 4 days straight.
Come to Russia, some place like Yekaterinburg. Or Saint-Petersburg, where the sun can be unseen for months.
In fact Denmark gets about 65% of their power from wind. The UK also gets a lot of their power form wind. For many norther countries, wind power has quite a lot of potential.
Not true. Just 47% [1], and Denmark is a country with the most favorable conditions for wind generation. Statistics are easy to manipulate if you allow yourself to add 15 percent here, subtract 15% there..
Also, Denmark relies on Sweden (who utilize nuclear power a lot) and Norway to provide power when renewables are not providing enough power

You refer to 2019 when renewables gave 50% of Danish power.

Yes, but the capacity for import and export is limited. Despite these limitations Denmark has managed to run on 65% wind power in 2020 without breaking the grid.
Thanks to COVID19 we get a look at the future in terms of how much of electricity production renewables can handle.
Also, how would an average western country power itself at nights, if all it has is 50m2 solar on every roof top?
