How much additional wind + solar + storage would you need to eliminate coal+ gas from this grid? (Not to mention the additional future loads from the electrification of heating & transport)

What's your point? It obviously isn't that it's a major task because everyone knows that. Just as it's been a major task to create the grid we have now.

The point is that it's an impossible task. Even Germany doesn't have enough money to do that.

Is there a way to ban all those unconstructive clowns who use cherry-picked hours to try to make points about systems that run 8760h a year?
Yes, there is a lot of work to do. And sunless winter-morning weekdays are probably the hardest to decarbonize, thanks Mr Obvious.

Nick Touran has done a “do the math”, graphical explanation for a 100% all energy replacement via a solar+storage case for CA. Method applies anywhere. Ex: Increase solar generation 20X, install 700 GWh of storage, for a daily case only.

It's mostly a storage problem. There's large gaps with little output

You're asking the wrong question.
Like how many cyclists with dynamos on their bikes would it take for Germany to eliminate coal and gas?
Try this question:
How much renewables does Europe need to eliminate coal and gas? And how much interconnect does Germany need?

I understand heating is being addressed using more direct methods, storing heat and distributing to communities is already well established in many places. Thus the daytime excess can be timeshifted

"Eliminate" is the common strawman. The last 10% is hardest. 90% gone by 2050 or earlier will do the job. Doable with today's tech, never mind what will be coming along.

In Germany we constantly hear how cheap renewables are. Yet our utilities bills tell a different story. In few countries people pay more. When you factor in backup power for when renewables are not producing, the total cost is high. And it isn't even working in the end.

You need to look at an interconnected grid, across a continent with plenty of cables running over wide space.

Burning FF is finite so renewables have to be used at some point. A balanced grid is needed or smaller populations of humans and less stuff is needed.
