Question

What are the amounts of energy produced, consumed, imported, and exported in Stuttgart in 2025?

Answer

⇤--#: . Rcode for using the ovariable is needed. --Jouni 23:03, 26 February 2013 (EET) (type: truth; paradigms: science: attack)

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 Stuttgart 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.
