The pencil uses Thermal energy
Mechanical pencils themselves do not need any energy in the forms of battery or electricity. However, mechanical pencils do need human energy to work. We need to add lead and push lead out; they do not do this on their own.
Mechanical pencils, like the regular kind of pencils, use graphite.
The "lead" in pencils is actually graphite, not the toxic metal lead. The confusion originates from the historical use of actual lead in pencils, but modern pencils use graphite because it is non-toxic and writes smoothly. Referring to pencil material as "lead" can be misleading and potentially harmful due to the toxicity of real lead.

The pencil sharpener was invented to help maintain the sharpness of pencils for writing and drawing purposes. It made the process of sharpening pencils quicker and more convenient compared to older methods like using a knife. It enhanced the efficiency and accuracy of pencil use.

No, LED (Light Emitting Diode) is not used in pencils. Pencils are traditionally made with graphite or a mixture of graphite and clay for the writing core. LED refers to a type of electronic light source, not suitable for writing instruments like pencils.
