[Tagging] Feature Proposal - RFC - electricity=*

While the original proposal did specify that generators are usually 
diesel, broadening the definition would only lead to a loss of detail, 
but the tagging would still be correct. I'm hesitant to use *offgrid* as 
a building that has, for example, a grid connection with solar panels on 
the roof would then be tagged as *electricity=grid;offgrid* instead of 
*electricity=grid;generator*. The former is illogical.

However, I don't have any experience in developing countries: is it 
easier to verify if something is off-grid compared to if it is connected 
to a generator? And, would it be necessary to differentiate between 
local grids (i.e. 2-3 generators, no substations, transfromers, etc.) 
and national grids? Perhaps then a network tag would be useful, i.e. 
network=national, local, regional similar to the way cycle networks are 

A further suggestion was to change the tagging 
to***electricity:grid=yes/no/backup* and/or 
*electricity:generator=yes/no/backup*. This might be less ambiguous for 
tagging amenities or buildings that get electricity from both sources 
and would then be more consistent with tagging such as 
*electricity:generator:origin=diesel* when, e.g. a building has a backup 
diesel generator but is connected to the grid. Unfortunately, it would 
then not be consistent with the use by the Healthsites Mapping Project, 
although this already has the inconsistent *electricity=none* tag which 
should probably be changed directly to *electricity=no.*

Cheers, Lukas
