I think the elephant has been well acknowledged by all parties but thanks for the reminder. I will stick to the approved list of talking points in the future... :roll:
If by 'approved' you mean pertinent and relevant to the context then YES. E.g., I could mention out of the blue that the progressive vote was fragmented but that would be useless spin. The pertinent information would be the ~ 90% majority.

Likewise, I could say that it is false to call the Repuke electorate AGW denialists. That is correct since ~ 15% of that group realize that climate change is anthropogenic. However, the tone, politicians and laws reflect the denialism of the supermajority 85% of that group so my original statement is just spin.
And round and round we go...

I hope you are incorrect. We (and our descendants) might manage to avoid all potential future disasters, or at least survive them.

If that is what you are suggesting, I agree it probably will not work. Perhaps you might want to rethink the problem.

I have not read through all 17 pages of this thread, so maybe this has been discussed ....

The thing that's stopping us right now is that, as long as we have gear on the roof that can generate 5kw when the sun is shining, we'd like to be able use that power when the grid is down; this is not uncommon where we live. Unfortunately, the PV installers are not interested in doing this without using expensive lithium-ion battery systems like the PowerWall; this would more than double the cost of the system we're thinking of installing. We prefer a more modest solution that involves single-digit kilowatt-hours of AGM (or maybe lead-acid) storage; that's still enough to run the fridge & cable modem a day or two and run the well pump enough for drinking and a little washing. I don't know if the installers don't want to bother unless it's as expensive as PowerWall etc, or if the PowerWall deals with a lot of the complication for them.

But a lot of complication there is. I've been debating how to do it with some smart people at stackexchange (and I'm an EE) and the answer is not clear to us. A lot of the complication has to do with the stricter "rapid shutdown" requirement of the 2017 NEC.

So that's gonna stop us, at least until I can figure out how to do it. I just can't see having all that power generation on the roof and not being able to use it when the grid goes down.

Check out the sunny island or StorEdge inverters. I think StorEdge only works with Powerwall and LG Chem batteries, but Sunny Island works with a variety of battery packs. It still likely won't be cheap, though...

The biden administration want to reduce solar install cost by 60%.
If you delete any associated taxes , permits fees, inspection costs, make the panels and inverter free you can just about get there.

What is the average install cost now?

The biggest cost is the installer isn't it?

In my area it was running 3 to $4 per DC watt installed, before tax credit. I did it myself and the cost ended up almost exactly at $1 per watt after tax credit, or about $1.5 per watt before the tax credit. I'm sure costs very wildly. Tesla solar appears dirt cheap.

But at $1 per watt installed with my expected output over twenty years, I'm looking at 4 cents per kWh. That's seems good to me.

Check out Outback power inverters, they are adaptable to any batteries so you coukd start with a couple of lead-acid deep cycle batteries and go to L-ion later. The Outback also complies with all necessary shutdown protocols and will sell back once your battery bank is charged. We have had a system like this for years - high-line power went out last night here and we only know it because we get a text from the power company, then we know not to be using heavy electric loads such as the coffee machine 'till it comes back on.
