Last year, China generated 834 terawatt-hours of solar power.
Which is more than the G7 countries generated, and more than the US and EU combined. In fact the only country group that generates more solar power than China is the OECD, all 38 countries of it.

Las Vegas has already achieved 97% storage supply for its needs - a city that barely sleeps at night.

“It’s not all happening right now,” is not even close to a convincing answer. If that was the reason to exclude any technology, there’d be none.
And it’s an especially ironic answer given that it takes up to 20 years to commission a nuclear power plant. And they are down for scheduled maintenance for up to a month a year, etc.
