Question

What are the amounts of energy produced, consumed, imported, and exported in Suzhou?

Answer

Rationale

There are several energy transformations that each describe a specific process of energy production or use. Per unit activity, there is a constant amount of different inputs and outputs into and from this process, respectively. These unit processes are used for Suzhou in such a way that one critical input or output from each relevant energy transformation is listed here; all other inputs and outputs logically follow from the nature of the transformation process.

A data table on an Opasnet page is used to enter the matrix data. This is rather user friendly. As a side effect, the table does not look like a matrix so it might be confusing in the beginning. The matrix is created by using the "Equation" as information about the row of the matrix and "Col" as information about the column of the matrix. "Result" is the actual value, and Description is anything useful for a reader (it is not used in calculations).

The model first creates the matrix and shows it to the user, 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, and the default values are based on the Kuopio data.
