⇤--#: . What are other energy sources,i wish it should be specific,how about air transport,does it included in the energy balance calculation? --Sam0911 16:29, 10 February 2013 (EET) (type: truth; paradigms: science: attack)

Use a table where different fuel types are columns and different stocks, energy production processes, or consumption types are rows called Energy accounts (Ene.account for short). See also an example File:Energy supply in Europe.xls. All Ene.accounts and fuel types used are listed on Energy consumption classes.

A part of a full energy balance sheet (ktoe/a).
Coal and peat Crude oil Petrochemical products Electricity Heat
Production and supply of primary energy
Production 129
Import 28 63
Export
Conversion of primary energy to use
Transfers
Electricity plants
CHP plants -129 -28 61 96
Final energy consumption
Industry
Road transport 54
Heating 10 96
Other energy use 9 51

Energy balance can be considered as double-entry bookkeeping. The production and conversion are typically credit (i.e., where the energy comes from), while consumption is debit (i.e., where the energy is used). In a typical case, both credit and debit are marked positive on the energy balance sheet. However, there are activities that convert one fuel to another, so that the energy is moved from one column to another. In this case, credit (the source) is marked negative and debit (the target) is marked positive. This is because the production and conversion rows together should reflect how much energy is actually available for final consumption. In other words, the sum of production and conversion rows should equal the sum of the consumption rows in every column.

Because production + conversion = consumption, also production = consumption - conversion. These equations are used to derive the supply that is needed to fulfil the demand.

----#: . it seems the formula is ok,the code also runs --Sam0911 16:33, 10 February 2013 (EET) (type: truth; paradigms: science: comment)=== Formula ===

Consumption of electricity by industry:

Consumption of electricity by commerce:

Consumption of electricity by municipality:

Consumption of district heat by households:

+ Show code

The model first creates the matrix (and shows it to the user if the user has defined intermediates = TRUE), and then it fills all empty cells with 0 and solves it by using the input values the user has given via the user interface. (The user interface can later be replaced by another model.) All the current input values are final consumptions. The example interface and values are based on the Kuopio data, but they are not stored as a part of the ovariable.

----#: . good to have a reference to compare --Sam0911 16:12, 10 February 2013 (EET) (type: truth; paradigms: science: comment)==See also==
