Calculate aggregate (total) efficiencies

Source: R/efficiency.R
calc_eta_pfd.Rd

Calculates aggregate (total) primary-to-final demand (gross and net) efficiencies across the energy conversion chain. .aggregate_df is probably formed by joining the results from primary_aggregates() and finaldemand_aggregates() or by calling footprint_aggregates(). See examples.

Usage

calc_eta_pfd(
  .aggregate_df = NULL,
  efficiency_name_suffix = Recca::efficiency_cols$efficiency_name_suffix,
  aggregate_primary_colname = Recca::aggregate_cols$aggregate_primary,
  gross_aggregate_demand_colname = Recca::aggregate_cols$gross_aggregate_demand,
  net_aggregate_demand_colname = Recca::aggregate_cols$net_aggregate_demand,
  energy_type = Recca::psut_cols$energy_type,
  last_stage = Recca::psut_cols$last_stage,
  eta_pfd_gross = Recca::efficiency_cols$eta_pfd_gross,
  eta_pfd_net = Recca::efficiency_cols$eta_pfd_net,
  eta_pfd_gross_colname = paste0(eta_pfd_gross, efficiency_name_suffix),
  eta_pfd_net_colname = paste0(eta_pfd_net, efficiency_name_suffix)
)

Arguments

.aggregate_df

A data frame or list containing columns aggregate_primary_colname, net_aggregate_demand_colname, gross_aggregate_demand_colname, probably the result of calling footprint_aggregates().

efficiency_name_suffix

The suffix for efficiency names. Default is Recca::efficiency_cols$efficiency_name_suffix.

aggregate_primary_colname

The name of the column in p_aggregates that contains primary energy or exergy aggregates. Default is Recca::aggregate_cols$aggregate_primary.

gross_aggregate_demand_colname

The name of the column in finaldemand_aggregates that contains gross final demand aggregates. Default is Recca::aggregate_cols$gross_aggregate_demand.

net_aggregate_demand_colname

The name of the column in finaldemand_aggregates that contains net final demand aggregates. Default is Recca::aggregate_cols$net_aggregate_demand.

energy_type

The name of the energy type column. Default is Recca::psut_cols$energy_type.

last_stage

The name of the last stage column. Default is Recca::psut_cols$last_stage.

eta_pfd_gross

The name of the output column containing efficiencies of converting primary energy into gross final demand energy. Default is Recca::efficiency_cols$eta_pfd_gross.

eta_pfd_net

The name of the output column containing efficiencies of converting primary energy into net final demand energy. Default is Recca::efficiency_cols$eta_pfd_net.

eta_pfd_gross_colname

The name of the output column containing names of gross efficiency parameters. Default is paste0(eta_pfd_gross, efficiency_name_suffix).

eta_pfd_net_colname

The name of the output column containing names of net efficiency parameters. Default is paste0(eta_pfd_net, efficiency_name_suffix).

Value

A data frame of aggregate efficiencies.
