calc_E_EIOU: Calculate embodied EIOU per industry output

In MatthewHeun/Recca: R Energy Conversion Chain Analysis

Calculate embodied EIOU per industry output

Description

This function calculates the EIOU per industry output given a .iomats data frame input-output matrices for an energy conversion chain. The returned E_EIOU matrix contains the by-product EIOU used by unit of each industry output, while the e_EIOU vector contains the total EIOU by unit of industry output.

Usage

calc_E_EIOU(
  .iomats = NULL,
  g = "g",
  U_EIOU = "U_EIOU",
  E_EIOU = "E_EIOU",
  e_EIOU = "e_EIOU"
)

Arguments

.iomats	a data frame containing matrices that describe the Input-Output structure of an Energy Conversion Chain. .iomats will likely have been obtained from the calc_io_mats() function.
g	name of the g vector on output. Default is "g".
U_EIOU	name of the U_EIOU matrices on output. Default is "U_EIOU".
E_EIOU	name for the E_EIOU matrix on output. Default is "E_EIOU".
e_EIOU	name for the e_EIOU vector on output. Default is "e_EIOU".

Details

The output E_EIOU matrix is calculated as U_EIOU %*% g_hat_inv.

The output e_EIOU vector is sum of E_EIOU columns: transpose(i) %*% E_EIOU.

Value

List or data frame containing the E_EIOU matrix and e_EIOU vector.

Examples

library(IEATools)
UKEnergy2000mats %>%
   dplyr::filter(Last.stage == "Final", Energy.type == "E") %>%
   tidyr::pivot_wider(names_from = "matrix.name", values_from = "matrix") %>%
   calc_io_mats() %>%
   calc_E_EIOU()
