Question

What are the typical energy processes in different Urgenche cities? Processes are events where energy if converted from one form to another or one use to another.

Answer

This code gets the ovariable of this page and calculates some basic results.

+ Show code- Hide code library(OpasnetUtils) # A package with Opasnet functionalities library(xtable) # A package with table formats library(ggplot2) # A package with fancy graph formats objects.latest("Op_en5472", "calculations") # Get the latest ovariables from code calculations on page Op_en5472. energyTransformations <- EvalOutput(energyTransformations) print(xtable(energyTransformations@output), type = 'html') # Show a result table ggplot(energyTransformations@output, # Show a bar chart aes(x = Energysource, y = emissionfactorresults, fill = Year)) + geom_bar(position="dodge") + theme_grey(base_size = 24)

Rationale

Energy transformations describe energy flows between cells in an energy balance sheet. For example, see op_fi:Energiatase/Kuopio.

Numbers are just rough placeholders at the moment.
