[Tagging] Feature Proposal - RFC - electricity=*

[Lukas Richert]

Hi François,

the combination of electricity:grid=yes with either electricity:origin=* 
or electricity:grid:origin=* would point to the origin being only about 
financial flows as advertised on-the-ground.

For the purpose of filtering out amenities, e.g. charging stations, that 
only use 'green' electricity it is still useful to tag 
electricity:origin=* or electricity:generator:origin=* in combination 
with electricity:generator=yes. Alternatively, there would need to be a 
tagged relation to the specific generator and the end users it supplies 
which would be considerably harder to query and many OSM editers seem to 
find relations confusing. Therefore, I think the slight bit of 
redundancy is useful to explicitly tag this on the amenity. Furthermore, 
the word 'origin' is used, not only to avoid two tags with very similar 
meanings that can be easily distinguished by combination with the 
infrastructure tag, but also since 'electricity:source' would then have 
a double meaning with 'the survey/map/place where the knowledge of the 
electricity was obtained', which is apparently a problem for some other 
tags using source as a keyword.

Cheers,

Lukas
