Even the people who understand the scale don't understand the purpose.

The Chinese grid isn't renewable or non-renewable. It's built to keep the lights on for anything short of a thousand year catastrophe.

Their 2060 plan has enough non intermittent base load that they can run the whole country off it for a decade.

That half of your grid capacity is there 'just in case' is something no one in the west can wrap their head around. China building out massive solar and wind farms isn't because wind and solar are the future. It's because they can tick off their 30 year plan 25 years ahead of schedule and focus on the hard parts next.

I think a major factor is politics - when China's leadership sets out to do something, they go out and get it done. Look at China's high speed rail (now more than the combined rest of the world), renewable energy growth, and their recent investment in chips. They commit to it, and make incredible progress - far outpacing everyone else. China's leadership seems to plan for the long term in infrastructure.

Compare that to something like the California High Speed Rail, or our every 4 year tug of war for elections (and mid term elections). Everything is short sighted "wins" for the next reelection, of one party vs another party, instead of making actual progress.

Its almost like when there is a good benevolent leadership in charge, for a long term, then progress comes much faster. (Singapore, China, ?)
