Calculate the E matrix for embodied energy calculations

Usage

calc_E(
  .iomats = NULL,
  R = "R",
  V = "V",
  U_feed = "U_feed",
  g = "g",
  r = "r",
  E = "E"
)

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.

R

A resources (R) matrix or name of column in .iomats containing same. Default is "R".

V

A make (V) matrix or name of column in .iomats containing same. Default is "V".

U_feed

A feedstock use (U_feed) matrix or name of column in .iomats containing same. Default is "U_feed".

g

A g vector or name of column in .iomats containing same. Default is "g".

r

An r vector or name of column in .iomats containing same. Default is "r".

E

The name for the E matrix on output. E is calculated by W %*% g_hat_inv. Default is "E".

Value

A list or data frame containing E matrices.
