Firstly solar is mathematically positive whilst everything from Earth is mathematically negative.
Secondly, no bulk storage batteries are needed with hydrogen backup.
Thirdly Fusion is an investor dream which is only slightly closer now than it was sixty years ago, despite having swallowed an awfult lot of investor funds (Which itself equates to energy wasted btw), the problem of replicating the gravity of the sun to get more power out, than goes into the equipment artificially simulating the gravity, is the modern version of pursuing a perpetual motion machine, practically impossible.
Energy polarity has to be taken into account in the case of the energy that supplies humanity in the same way as in any machine we build.
We are not doing that, when we bundle together all kinds of energy from Earth with the energy from the sun.
There is actually no such thing as Renewables, that is a profit driven confusion machine, which could not have been better designed to confuse, to allow millions of bullshit profit driven business ideas (Businesses employing people in bullshit jobs, as identified by the late David Graeber), to hide within the confusion, pretending to help fix the problem, when actually it all makes it worse, all are wasting energy making business from destruction, just as big pharma makes profit from illness.
But it is all becoming clear now.
I hope you see this too, soon enough.
I disagree with you on what we are seeing flattening out, this is wishful thinking on the part of profit driven business, it is the oppposite, tending towards vertical, like the walls of a plughole.
I also disagree that other countries will not see the same, there is plenty of data around, indicating we are all similarly advanced, UK is actually nowhere near the front. Check Vietnam, and even Germany, if you have doubts.
Just watch the inflation, that will convince everyone soon enough, I hope, for all our sakes.
