> Where?

Almost the entire world? The sun is up for less than 9.5 hours in winter unless you are very close to the equator.[1][2][3][4]

And that's assuming 0% cloud coverage. In reality, places like Germany only get an hour or two of real sunshine a day in the winter[5].

The middle of winter in Europe, North America, and Asia is the middle of summer in South America, Southern Africa and Australia. Yes, global transmission of electricity is a problem. But the problem is not a global lack of sunshine.

Land - and thus population - is not evenly distributed across the globe, there is far more of both in the northern hemisphere.

Global transmission of electricity isn't a "problem," it's non-existant.

Long distance power transport is tricky for security reasons and also transmission losses (1% per 100 miles or so?).

Europe tried a very global approach to energy with Russia, went swimmingly for them.

Which is why it's so important to make Russia pay dearly. They didn't just attack Ukraine, they attacked civilization.

Russia must be confronted with economic, political, and yes, military incentives to behave very differently in the future.

Transmission losses seem like a huge impediment to a global approach.
