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.

• CHP = Combined heat and power
• CO2e = CO2 equivalents. This is the official number which assumes that bioenergy CO2 is absorbed and the net emission is thus 0.
• CO2a = CO2 additional emission. This does not assume absorption but estimates the direct CO2 emission, additional to CO2e.

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.
