The categorization of classical works is done according to opus and movement. The opus number is a way of organizing a composer's works in chronological order, with each opus containing a collection of compositions.

Each movement is typically numbered and has its own distinct musical character and structure. By organizing classical works according to opus and movement, it becomes easier for musicians, scholars, and enthusiasts to reference and study these pieces within the broader context of a composer's body of work. **

Some energy cost meters also provide additional features such as tracking historical usage, setting energy usage goals, and identifying energy-wasting appliances. **
