They get dirty, they are not as accurate as an optical mouse, and like anything with a moving part they will wear out.

Optical mouse: Most desktop computer users today have some type of optical mouse, which uses devices that emit and sense light to detect the mouse's movement.

The movement of a mouse refers to the physical action of the device as it is moved across a surface, which translates into cursor movement on a computer screen. This is achieved through various technologies, such as optical sensors or ball-based mechanisms, that detect the motion and direction of the mouse. The movement can be used for a range of tasks, including navigation, selection, and interaction with software applications. Overall, mouse movement is a crucial aspect of user interface navigation in computing.
Optical...If im not mistaken.
The energy is mechanical energy from the physical movement of the mouse running on the wheel.

A floating toolbar that remains in a fixed position on the screen as the user scrolls can minimize mouse movement. Additionally, grouping related functions together on the toolbar can further reduce the need for excessive mouse movement. Keyboard shortcuts for frequently used functions can also help minimize reliance on the mouse.

A track ball mouse is a mouse that uses an internal ball to track movement, instead of a laser. These have been outdated by optical mice.
I use the mouse for directional, with WASD mapped for actual movement. Some player use the arrow keys for more independent movement and targeting.
Just move the mouse around, the cursor (mouse pointer) should follow your movement on the screen.
