peak hours and off peak hours should be easy, as the addition of unit cost for each and subscription part.

For the CO2, at least an average should be known, but to be more precise, the averages for :
  • seasons : renewable energies are more used in summer (*)
  • and use of the electricity : the constant consumption is feeded by hydro () and nuclear () which generate less CO2, while heating is feeded by coal which generate more CO2.
(*) my provider broadcasts their monthly CO2 generation per kWh regularly.
All that to say that CO2 support may be complicated.

On my spreadsheet I record for each month :
  • Average off Peak kWh per day
  • Average peak kWh per day
  • Average cost per day (without subscription)
  • Average cost per kWh (without subscription)
  • and % of in/de-crease for these 4 with last month.

Denis.
