 ## Effects
 
 Flixopt introduces a freely definable system of evaluation metrics called *Effects* such as costs, emissions, primary energy demand, or any user-defined indicators. Any structural entity can contribute shares to any *Effect* and *Effects* can contribute to each other. This abstraction through *Effects* has the following advantages over a traditional rigid objective, as it generically integrates the following features:
+
 * Switch the objective to another *Effect* easily, once *Effects* and a flow-system are defined.
 * Include as many evaluation metrics as needed to simplify the evaluation of the solution.
   * Example: Instead of a global objective ’costs’, you could divide it into ’energy costs’, ’labor costs’, ’funding’, ’revenues’ and more, which all have a share to the ’net total’. This way it is possible to access these metrics individually after the optimization.
