And still globally the fraction of renewables in electricity gen, and even primary energy consumption (counting renewable elec gen as “primary”), remains pretty steadfast at the levels of the 1990s
I think this might be out of date info, renewables (thanks mainly to china tbh) are now the cheapest form of power and surging with installations:

Savings are not totally pointless, but reducing prices of something does tend to increase consumption
Good old Jevons
Adding new generation capacity has some similarity to adding a new lane to a busy highway. Induced demand.
I don't agree with this, yes there is an increase in energy usage, I am technically using more electricity than ever from thanks to cheap solar because I fill up my car with 40kw worth of electricity every few weeks, but at the same time I now use 0L of petrol and no gas at all so it's not exactly adding a lane to the highway if I've reduced my energy use elsewhere and added it on to renewables, it's the same number of lanes but now I'm 100% renewable
We also have visible signs it's eating into fossil fuels:

The Australian Energy Market Operator is predicting that the country’s remaining coal fired generators are likely to close much quicker than expected, saying they are becoming less reliable, more difficult to maintain and less able to compete with the growing share of renewables.
AEMO’s draft 2024 Integrated System Plan, the latest version of its 30-year planning blueprint, suggests coal fired generation will be gone from Queensland and Victoria within a decade – by 2033/34 – and that the last coal unit will close in NSW by 2038.
Same will be with transport, if you don’t ban petrol, and just subsidise electric transport, there’ll be more trips you wont reduce petrol consumption
This doesn't make sense to me, if you were talking about cheaper petrol then sure, but if I replace my petrol car with an EV, even if I do more trips it's still electricity, petrol usage has dropped to 0 despite an increase in trips
And we're still in the very early years with EV's, we have only just started pushing out electric trucks and buses, speaking of: Brisbane just got our first electric buses earlier in the year!

They are so quiet it's crazy!
tldr: I think your premise is that electricity usage is increasing and renewables are supplying it but not eating into fossil fuels and I don't think this is true, the last few years solar, EV and battery innovation has been leaps and bounds
As an example I bought this in Jan 2023 for 14k: https://sonnen.com.au/sonnenbatterie-evo/
10kw
Today for 5.5k I can get 40kw:
