CO2e

[mathgim]

Hi,
I got an idea to addon to your component. A sensor to tell the CO2e emission.
In France (as I guess it is the case for most users of this component), it is approximatively 200g of CO2 per kWh.

What do you think to have a sensor to provide this value per day and per month? So that we can make people realize their consumption. And we could compare it easily to the COP21 quota per habitation.
