[ENHANCEMENT] Handling countries very low carbon energy grid

[mrchrisadams]

Is your feature request related to a problem? Please describe.

Some regions of some countries have extremely low carbon grids, which means that the energy is essentially green by default, at least in terms of average carbon intensity.

Quebec is the canonical example as outlined below - with very very clean electricty - almost 100x lower then the national average for Canada.

I'm not aware of these regions selling off the "greenness" of their generation on the market the way other countries do so that generation elsewhere can be marked as green, like some Nordic states do, so it would be good to recognise this.

Electricity map data uses open data and exposes a commercial API. We don't need that level of resolution for what we do/
Ember's data works at a natinoal level, is free, and we use it at present.

Wattime is a commercial API that provides higher temporal res than we need, and is marginal data. Not the same.
The UNFCCC annual marginal data, works at a national level.
