1.740 × 10^17 W ≈ total power received by Earth from the Sun
1.91 × 10^13 ≈ average total power consumption of the human world in 2019
> If we are quick
I don't know about the growth of batteries other than "factories are being made as fast as they can be, and car companies are investing in mines now", the growth of PV is still approximately exponential. Also, if PV production switches from growth to fixed output at the end of this year, given how long the stuff lasts, it would end up in a steady state of about 8 TW nameplate capacity; given what the capacity factor is like, in practice that would be enough to make all electricity green but not enough to electrify everything else.
I'm not expecting the exponential to come to a sudden stop at the end of this year.
> most small succeed...
Do they, though? I think you're just not hearing about most of the small failures because they're boring.
About projects, in any field, big, complex projects normally never get done well, smaller normally succeed. That's is. Since it's valid from IT to A&D why it should be different for something else?
Off topic, but why do you consistently spell "which" as "witch"? I sympathise if it's ESL, but if so: the latter refers to pointy hats and pentagrams, not a determiner.
I'm a bit skeptical, but in any case consider a thing: we need to count an initial construction BUT also a regular substitution of old modules, managing their disposal (witch actually is just shred and bury in most cases) and in doing so we need to count the life cycle: if we construct something slowly things reach EOL in small batches so we can keep a regular production since the initial demand is not hyper-big and the future substitution rate start BEFORE the initial demand finished and keep a slow rate. If we are quick:
- we need a monster production to satisfy the demand
- then the demand drops equally sharply and you get hyper-big factories who do almost nothing
- the the demand skyrocket again
If you think it's theoretical see actual Italy: a gazillion of CA infra was built quickly in few years after WWII, now are en equal batch EOL... There is a reason, more than one, why almost any big project end up badly while most small succeed...
