You don't imagine, how large part of world, which have at least two months year, with near 90% fall of solar energy.

And they have to use traditional energy sources, or buy energy from neighbors.

I only mentioned solar/battery for brevity but clearly wind/battery is already substantial in many parts of the world. In addition, HVDC transmissions line costs are also dropping year by year and these allow solar/wind generated electricity to be inexpensively shifted across long distances.

For example, such a transmission line is currently being built to send solar energy from Northern Australia to Singapore across about 3000km of ocean. Another project is generating wind energy near Iceland and sending it to the UK a distance of 800km.

Ok, and thank You for remember about Australia to Singapore transmission line.

Unfortunately, most of territories I mention, also have low population density, about 1/10 of western Europe, and have low middle income, so it is not right to directly compare them with western Europe or Singapore, in possibilities to achieve same infrastructure power.

There's well under a hundred million people that aren't within easy transmission distance of somewhere with at least 10% capacity factor for a bifacial system in mid winter and don't already have more than enough hydro to go wind/hydro.

If 1% of the world needs to get 30% of their energy from gas while we figure out the hydrogen thing, it's not really a problem.
