Standardize Units For SCI

[will-iamalpine]

Propose we standardize around units for reporting & methodology (e.g Joules/kWh/ (gCO2eq/kWh))

The carbon intensity of electricity is a measure of how much carbon (CO2eq) emissions are produced per kilowatt-hour (kWh) of electricity consumed, for a standard unit of gCO2eq/kWh.

Let's use a good metric measurement if possible!

Some immediate thoughts:

• Energy (Joules? kWh?)
• Location-based carbon intensity MOER (I)
• Embodied carbon (kg? g? lbs?)

@Henry-WattTime last time I dug into WattTime's documentation, it was really hard to find units within WattTime's documentation around carbon. I think I did't find a clear delineation between kg and lbs. Is this something you can add to WattTime's documentation help surface?

Thanks for bringing this up @buchananwp - I think the more international units we use the better, i.e. avoiding the use of lbs and other non-metric units would be preferable to gain global traction.

Also, @buchananwp can you make a separate issue for defining MOER for the GSF Dictionary? Thanks!

g CO2/kWh seems to be the most comfortable unit for everyone, and Will points out that we can use scientific notation as we need larger numbers.
