In CfSOtago/gridCarbon: Code to analyse the carbon footprint of NZ electricity generation over time

nzCalculateCO2e calculates the CO2e emissions (in kg) per fuel per half-hour.

Description

Uses the EA grid generation data to sum yearly kWh by fuel and combines with the NZ efficiency and emission factors published at https://www.mbie.govt.nz/building-and-energy/energy-and-natural-resources/energy-statistics-and-modelling/energy-statistics/new-zealand-energy-sector-greenhouse-gas-emissions/

Usage

nzCalculateCO2e(dt, ef)

Arguments

dt	the data table with the half-hourly kWh values per fuel (do not include incomplete years)
ef	the MBIE emission factors file

Details

Returns a data.table of carbon intensity (gCO2-e/kWh) per fuel per year for further use

Notes:

* we estimate the factors each year by dividing the MBIE per-year totals (kt CO2-e) by the total per fuel per-year kWh in the data.table and then converting to g/kWh. If MBIE published the conversion factors this would not be necessary. But if they do, we have not been able to find them.

* the geothermal conversion _may not_ include fugitive emissions (?)
