Agree with that.
electricity:grid:origin isn't part of the proposal, will we have to approve

Don't agree with that :)
This filtering won't be accurate at all and will encourage people to think
claimed origin through a power grid is equivalent to certainty of locally
obtained electricity (which isn't)
I'm clearly against any association between a generator device and 'origin'
word. electricity:origin should relate to grid/market only and remain a
claim with no physical reality.

Understood, that would enable to check consistency as well.

I respectfully disagree, they don't have a similar meaning in many
Merging both in a single key will only be accurate when the claim is
equivalent to local production which isn't necessary: you buy solar energy
and backup with diesel more often than backup with solar.

i'm currently thinking about refine generator:* subkeys and it's sure this
discussion will be really inspiring.
Indeed source should be avoided and I keep that in mind.
In power context "source" refers to inputs and as we already have
generator:output, why shouldn't we have generator:input?
input:wind=X kW
output:electricity= Y kW

All the best
